Warning
torch.export and its related features are in prototype status and are subject to backwards compatibility
breaking changes. This tutorial provides a snapshot of torch.export usage as of PyTorch 2.5.
torch.export() is the PyTorch 2.X way to export PyTorch models into
standardized model representations, intended
to be run on different (i.e. Python-less) environments. The official
documentation can be found here.
In this tutorial, you will learn how to use torch.export() to extract
ExportedProgram’s (i.e. single-graph representations) from PyTorch programs.
We also detail some considerations/modifications that you may need
to make in order to make your model compatible with torch.export.
Contents
Basic Usage#
torch.export extracts single-graph representations from PyTorch programs
by tracing the target function, given example inputs.
torch.export.export() is the main entry point for torch.export.
In this tutorial, torch.export and torch.export.export() are practically synonymous,
though torch.export generally refers to the PyTorch 2.X export process, and torch.export.export()
generally refers to the actual function call.
The signature of torch.export.export() is:
export(
mod: torch.nn.Module,
args: Tuple[Any, ...],
kwargs: Optional[Dict[str, Any]] = None,
*,
dynamic_shapes: Optional[Dict[str, Dict[int, Dim]]] = None
) -> ExportedProgram
torch.export.export() traces the tensor computation graph from calling mod(*args, **kwargs)
and wraps it in an ExportedProgram, which can be serialized or executed later with
different inputs. To execute the ExportedProgram we can call .module()
on it to return a torch.nn.Module which is callable, just like the
original program.
We will detail the dynamic_shapes argument later in the tutorial.

Let’s review some attributes of ExportedProgram that are of interest.
The graph attribute is an FX graph
traced from the function we exported, that is, the computation graph of all PyTorch operations.
The FX graph is in “ATen IR” meaning that it contains only “ATen-level” operations.
The graph_signature attribute gives a more detailed description of the
input and output nodes in the exported graph, describing which ones are
parameters, buffers, user inputs, or user outputs.
The range_constraints attributes will be covered later.

See the torch.export documentation
for more details.
Graph Breaks#
Although torch.export shares components with torch.compile,
the key limitation of torch.export, especially when compared to
torch.compile, is that it does not support graph breaks. This is because
handling graph breaks involves interpreting the unsupported operation with
default Python evaluation, which is incompatible with the export use case.
Therefore, in order to make your model code compatible with torch.export,
you will need to modify your code to remove graph breaks.
A graph break is necessary in cases such as:

Non-Strict Export#
To trace the program, torch.export uses TorchDynamo by default, a byte
code analysis engine, to symbolically analyze the Python code and build a
graph based on the results. This analysis allows torch.export to provide
stronger guarantees about safety, but not all Python code is supported,
causing these graph breaks.
To address this issue, in PyTorch 2.3, we introduced a new mode of
exporting called non-strict mode, where we trace through the program using the
Python interpreter executing it exactly as it would in eager mode, allowing us
to skip over unsupported Python features. This is done through adding a
strict=False flag.
Looking at some of the previous examples which resulted in graph breaks:
Calling unsupported functions (such as many built-in functions) traces
through, but in this case, id(x) gets specialized as a constant integer in
the graph. This is because id(x) is not a tensor operation, so the
operation is not recorded in the graph.
class Bad3(torch.nn.Module):
def forward(self, x):
x = x + 1
return x + id(x)
bad3_nonstrict = export(Bad3(), (torch.randn(3, 3),), strict=False)

However, there are still some features that require rewrites to the original module:
Control Flow Ops#
torch.export actually does support data-dependent control flow.
But these need to be expressed using control flow ops. For example,
we can fix the control flow example above using the cond op, like so:
class Bad1Fixed(torch.nn.Module):
def forward(self, x):
def true_fn(x):
return torch.sin(x)
def false_fn(x):
return torch.cos(x)
return torch.cond(x.sum() > 0, true_fn, false_fn, [x])

[0.5403, 0.5403, 0.5403]])
There are limitations to cond that one should be aware of:
The predicate (i.e.
x.sum() > 0) must result in a boolean or a single-element tensor.The operands (i.e.
[x]) must be tensors.The branch function (i.e.
true_fnandfalse_fn) signature must match with the operands and they must both return a single tensor with the same metadata (for example,dtype,shape, etc.).Branch functions cannot mutate input or global variables.
Branch functions cannot access closure variables, except for
selfif the function is defined in the scope of a method.
For more details about cond, check out the cond documentation.
We can also use map, which applies a function across the first dimension
of the first tensor argument.

Constraints/Dynamic Shapes#
This section covers dynamic behavior and representation of exported programs. Dynamic behavior is subjective to the particular model being exported, so for the most part of this tutorial, we’ll focus on this particular toy model (with the resulting tensor shapes annotated):
class DynamicModel(torch.nn.Module):
def __init__(self):
super().__init__()
self.l = torch.nn.Linear(5, 3)
def forward(
self,
w: torch.Tensor, # [6, 5]
x: torch.Tensor, # [4]
y: torch.Tensor, # [8, 4]
z: torch.Tensor, # [32]
):
x0 = x + y # [8, 4]
x1 = self.l(w) # [6, 3]
x2 = x0.flatten() # [32]
x3 = x2 + z # [32]
return x1, x3
By default, torch.export produces a static program. One consequence of this is that at runtime,
the program won’t work on inputs with different shapes, even if they’re valid in eager mode.
w = torch.randn(6, 5)
x = torch.randn(4)
y = torch.randn(8, 4)
z = torch.randn(32)
model = DynamicModel()
ep = export(model, (w, x, y, z))
model(w, x, torch.randn(3, 4), torch.randn(12))
try:
ep.module()(w, x, torch.randn(3, 4), torch.randn(12))

raise RuntimeError(
RuntimeError: Expected input at *args[2].shape[0] to be equal to 8, but got 3. If you meant for this dimension to be dynamic, please re-export and specify dynamic_shapes (e.g. with Dim.DYNAMIC)
Basic concepts: symbols and guards#
To enable dynamism, export() provides a dynamic_shapes argument. The easiest way to work with
dynamic shapes is using Dim.AUTO and looking at the program that’s returned. Dynamic behavior is specified
at a input dimension-level; for each input we can specify a tuple of values:
Before we look at the program that’s produced, let’s understand what specifying dynamic_shapes entails,
and how that interacts with export. For every input dimension where a Dim object is specified, a symbol is
allocated,
taking on a range of [2, inf] (why not [0, inf] or [1, inf]? we’ll explain later in the
0/1 specialization section).
Export then runs model tracing, looking at each operation that’s performed by the model. Each individual operation can emit
what’s called “guards”; basically boolean condition that are required to be true for the program to be valid.
When guards involve symbols allocated for input dimensions, the program contains restrictions on what input shapes are valid;
i.e. the program’s dynamic behavior. The symbolic shapes subsystem is the part responsible for taking in all the emitted guards
and producing a final program representation that adheres to all of these guards. Before we see this “final representation” in
an ExportedProgram, let’s look at the guards emitted by the toy model we’re tracing.
Here, each forward input tensor is annotated with the symbol allocated at the start of tracing:
class DynamicModel(torch.nn.Module):
def __init__(self):
super().__init__()
self.l = torch.nn.Linear(5, 3)
def forward(
self,
w: torch.Tensor, # [s0, s1]
x: torch.Tensor, # [s2]
y: torch.Tensor, # [s3, s4]
z: torch.Tensor, # [s5]
):
x0 = x + y # guard: s2 == s4
x1 = self.l(w) # guard: s1 == 5
x2 = x0.flatten() # no guard added here
x3 = x2 + z # guard: s3 * s4 == s5
return x1, x3
Let’s understand each of the operations and the emitted guards:
x0 = x + y: This is an element-wise add with broadcasting, sincexis a 1-d tensor andya 2-d tensor.xis broadcasted along the last dimension ofy, emitting the guards2 == s4.x1 = self.l(w): Callingnn.Linear()performs a matrix multiplication with model parameters. In export, parameters, buffers, and constants are considered program state, which is considered static, and so this is a matmul between a dynamic input (w: [s0, s1]), and a statically-shaped tensor. This emits the guards1 == 5.x2 = x0.flatten(): This call actually doesn’t emit any guards! (at least none relevant to input shapes)x3 = x2 + z:x2has shape[s3*s4]after flattening, and this element-wise add emitss3 * s4 == s5.
Writing all of these guards down and summarizing is almost like a mathematical proof, which is what the symbolic shapes subsystem tries to do! In summary, we can conclude that the program must have the following input shapes to be valid:
w: [s0, 5]x: [s2]y: [s3, s2]z: [s2*s3]
And when we do finally print out the exported program to see our result, those shapes are what we see annotated on the corresponding inputs:

Another feature to notice is the range_constraints field above, which contains a valid range for each symbol. This isn’t so interesting currently, since this export call doesn’t emit any guards related to symbol bounds and each base symbol has a generic bound, but this will come up later.
So far, because we’ve been exporting this toy model, this experience has not been representative of how hard it typically is to debug dynamic shapes guards & issues. In most cases it isn’t obvious what guards are being emitted, and which operations and parts of user code are responsible. For this toy model we pinpoint the exact lines, and the guards are rather intuitive.
In more complicated cases, a helpful first step is always to enable verbose logging. This can be done either with the environment
variable TORCH_LOGS="+dynamic", or interactively with torch._logging.set_logs(dynamic=10):

Next to the [guard added] messages, we also see the responsible user lines of code - luckily here the model is simple enough.
In many real-world cases it’s not so straightforward: high-level torch operations can have complicated fake-kernel implementations
or operator decompositions that complicate where and what guards are emitted. In such cases the best way to dig deeper and investigate
is to follow the logs’ suggestion, and re-run with environment variable TORCHDYNAMO_EXTENDED_DEBUG_GUARD_ADDED="...", to further
attribute the guard of interest.
Dim.AUTO is just one of the available options for interacting with dynamic_shapes; as of writing this 2 other options are available:
Dim.DYNAMIC, and Dim.STATIC. Dim.STATIC simply marks a dimension static, while Dim.DYNAMIC is similar to Dim.AUTO in all
ways except one: it raises an error when specializing to a constant; this is designed to maintain dynamism. See for example what happens when a
static guard is emitted on a dynamically-marked dimension:

The error above occurred when calling torch.export.export. If you would like to view some more information about this error, and get a list of all other errors that may occur in your export call, you can replace your `export()` call with `draft_export()`.
Static guards also aren’t always inherent to the model; they can also come from user specifications. In fact, a common pitfall leading to shape
specializations is when the user specifies conflicting markers for equivalent dimensions; one dynamic and another static. The same error type is
raised when this is the case for x.shape[0] and y.shape[1]:

The error above occurred when calling torch.export.export. If you would like to view some more information about this error, and get a list of all other errors that may occur in your export call, you can replace your `export()` call with `draft_export()`.
Here you might ask why export “specializes”, i.e. why we resolve this static/dynamic conflict by going with the static route. The answer is because
of the symbolic shapes system described above, of symbols and guards. When x.shape[0] is marked static, we don’t allocate a symbol, and compile
treating this shape as a concrete integer 4. A symbol is allocated for y.shape[1], and so we finally emit the guard s3 == 4, leading to
specialization.
One feature of export is that during tracing, statements like asserts, torch._check(), and if/else conditions will also emit guards.
See what happens when we augment the existing model with such statements:
class DynamicModel(torch.nn.Module):
def __init__(self):
super().__init__()
self.l = torch.nn.Linear(5, 3)
def forward(self, w, x, y, z):

torch._check(x.shape[0] >= 4)
if w.shape[0] == x.shape[0] + 2:
x0 = x + y
x1 = self.l(w)
x2 = x0.flatten()
x3 = x2 + z
return x1, x3

Each of these statements emits an additional guard, and the exported program shows the changes; s0 is eliminated in favor of s2 + 2,
and s2 now contains lower and upper bounds, reflected in range_constraints.
For the if/else condition, you might ask why the True branch was taken, and why it wasn’t the w.shape[0] != x.shape[0] + 2 guard that
got emitted from tracing. The answer is that export is guided by the sample inputs provided by tracing, and specializes on the branches taken.
If different sample input shapes were provided that fail the if condition, export would trace and emit guards corresponding to the else branch.
Additionally, you might ask why we traced only the if branch, and if it’s possible to maintain control-flow in your program and keep both branches
alive. For that, refer to rewriting your model code following the Control Flow Ops section above.
0/1 specialization#
Since we’re talking about guards and specializations, it’s a good time to talk about the 0/1 specialization issue we brought up earlier. The bottom line is that export will specialize on sample input dimensions with value 0 or 1, because these shapes have trace-time properties that don’t generalize to other shapes. For example, size 1 tensors can broadcast while other sizes fail; and size 0 … . This just means that you should specify 0/1 sample inputs when you’d like your program to hardcode them, and non-0/1 sample inputs when dynamic behavior is desirable. See what happens at runtime when we export this linear layer:
ep = export(
torch.nn.Linear(4, 3),

Named Dims#
So far we’ve only been talking about 3 ways to specify dynamic shapes: Dim.AUTO, Dim.DYNAMIC, and Dim.STATIC. The attraction of these is the
low-friction user experience; all the guards emitted during model tracing are adhered to, and dynamic behavior like min/max ranges, relations, and static/dynamic
dimensions are automatically figured out underneath export. The dynamic shapes subsystem essentially acts as a “discovery” process, summarizing these guards
and presenting what export believes is the overall dynamic behavior of the program. The drawback of this design appears once the user has stronger expectations or
beliefs about the dynamic behavior of these models - maybe there is a strong desire on dynamism and specializations on particular dimensions are to be avoided at
all costs, or maybe we just want to catch changes in dynamic behavior with changes to the original model code, or possibly underlying decompositions or meta-kernels.
These changes won’t be detected and the export() call will most likely succeed, unless tests are in place that check the resulting ExportedProgram representation.
For such cases, our stance is to recommend the “traditional” way of specifying dynamic shapes, which longer-term users of export might be familiar with: named Dims:
This style of dynamic shapes allows the user to specify what symbols are allocated for input dimensions, min/max bounds on those symbols, and places restrictions on the
dynamic behavior of the ExportedProgram produced; ConstraintViolation errors will be raised if model tracing emits guards that conflict with the relations or static/dynamic
specifications given. For example, in the above specification, the following is asserted:
x.shape[0]is to have range[4, 256], and related toy.shape[0]byy.shape[0] == 2 * x.shape[0].x.shape[1]is static.y.shape[1]has range[2, 512], and is unrelated to any other dimension.
In this design, we allow relations between dimensions to be specified with univariate linear expressions: A * dim + B can be specified for any dimension. This allows users
to specify more complex constraints like integer divisibility for dynamic dimensions:
Constraint violations, suggested fixes#
One common issue with this specification style (before Dim.AUTO was introduced), is that the specification would often be mismatched with what was produced by model tracing.
That would lead to ConstraintViolation errors and export suggested fixes - see for example with this model & specification, where the model inherently requires equality between
dimensions 0 of x and y, and requires dimension 1 to be static.

Suggested fixes:
d1 = 4
dy = dx
The error above occurred when calling torch.export.export. If you would like to view some more information about this error, and get a list of all other errors that may occur in your export call, you can replace your `export()` call with `draft_export()`.
The expectation with suggested fixes is that the user can interactively copy-paste the changes into their dynamic shapes specification, and successfully export afterwards.
Lastly, there’s couple nice-to-knows about the options for specification:
Noneis a good option for static behavior: -dynamic_shapes=None(default) exports with the entire model being static. - specifyingNoneat an input-level exports with all tensor dimensions static, and is also required for non-tensor inputs. - specifyingNoneat a dimension-level specializes that dimension, though this is deprecated in favor ofDim.STATIC.specifying per-dimension integer values also produces static behavior, and will additionally check that the provided sample input matches the specification.
These options are combined in the inputs & dynamic shapes spec below:
inputs = (
torch.randn(4, 4),
torch.randn(3, 3),
16,
False,
)
dynamic_shapes = {
"tensor_0": (Dim.AUTO, None),
"tensor_1": None,
"int_val": None,
"bool_val": None,
}
Data-dependent errors#
While trying to export models, you have may have encountered errors like “Could not guard on data-dependent expression”, or Could not extract specialized integer from data-dependent expression”.
These errors exist because torch.export() compiles programs using FakeTensors, which symbolically represent their real tensor counterparts. While these have equivalent symbolic properties
(e.g. sizes, strides, dtypes), they diverge in that FakeTensors do not contain any data values. While this avoids unnecessary memory usage and expensive computation, it does mean that export may be
unable to out-of-the-box compile parts of user code where compilation relies on data values. In short, if the compiler requires a concrete, data-dependent value in order to proceed, it will error out,
complaining that the value is not available.
Data-dependent values appear in many places, and common sources are calls like item(), tolist(), or torch.unbind() that extract scalar values from tensors.
How are these values represented in the exported program? In the Constraints/Dynamic Shapes
section, we talked about allocating symbols to represent dynamic input dimensions.
The same happens here: we allocate symbols for every data-dependent value that appears in the program. The important distinction is that these are “unbacked” symbols,
in contrast to the “backed” symbols allocated for input dimensions. The “backed/unbacked”
nomenclature refers to the presence/absence of a “hint” for the symbol: a concrete value backing the symbol, that can inform the compiler on how to proceed.
In the input shape symbol case (backed symbols), these hints are simply the sample input shapes provided, which explains why control-flow branching is determined by the sample input properties. For data-dependent values, the symbols are taken from FakeTensor “data” during tracing, and so the compiler doesn’t know the actual values (hints) that these symbols would take on.
Let’s see how these show up in exported programs:
class Foo(torch.nn.Module):
def forward(self, x, y):
a = x.item()
b = y.tolist()
return b + [a]
inps = (
torch.tensor(1),
torch.tensor([2, 3]),
)
ep = export(Foo(), inps)
print(ep)

class GraphModule(torch.nn.Module):
def forward(self, x: "i64[]", y: "i64[2]"):
# File: /var/lib/workspace/intermediate_source/torch_export_tutorial.py:618 in forward, code: a = x.item()
item: "Sym(u0)" = torch.ops.aten.item.default(x); x = None
# File: /var/lib/workspace/intermediate_source/torch_export_tutorial.py:619 in forward, code: b = y.tolist()
unbind = torch.ops.aten.unbind.int(y); y = None
getitem: "i64[]" = unbind[0]
getitem_1: "i64[]" = unbind[1]; unbind = None
item_1: "Sym(u1)" = torch.ops.aten.item.default(getitem); getitem = None
item_2: "Sym(u2)" = torch.ops.aten.item.default(getitem_1); getitem_1 = None
return (item_1, item_2, item)
Graph signature:
# inputs
x: USER_INPUT
y: USER_INPUT
# outputs
item_1: USER_OUTPUT
item_2: USER_OUTPUT
item: USER_OUTPUT
Range constraints: {u0: VR[-int_oo, int_oo], u1: VR[-int_oo, int_oo], u2: VR[-int_oo, int_oo]}
The result is that 3 unbacked symbols (notice they’re prefixed with “u”, instead of the usual “s” for input shape/backed symbols) are allocated and returned:
1 for the item() call, and 1 for each of the elements of y with the tolist() call.
Note from the range constraints field that these take on ranges of [-int_oo, int_oo], not the default [0, int_oo] range allocated to input shape symbols,
since we have no information on what these values are - they don’t represent sizes, so don’t necessarily have positive values.
Guards, torch._check()#
But the case above is easy to export, because the concrete values of these symbols aren’t used in any compiler decision-making; all that’s relevant is that the return values are unbacked symbols. The data-dependent errors highlighted in this section are cases like the following, where data-dependent guards are encountered:
Here we actually need the “hint”, or the concrete value of a for the compiler to decide whether to trace return y + 2 or return y * 5 as the output.
Because we trace with FakeTensors, we don’t know what a // 2 >= 5 actually evaluates to, and export errors out with “Could not guard on data-dependent expression u0 // 2 >= 5 (unhinted)”.
So how do we export this toy model? Unlike torch.compile(), export requires full graph compilation, and we can’t just graph break on this. Here are some basic options:
Manual specialization: we could intervene by selecting the branch to trace, either by removing the control-flow code to contain only the specialized branch, or using
torch.compiler.is_compiling()to guard what’s traced at compile-time.torch.cond(): we could rewrite the control-flow code to usetorch.cond()so we don’t specialize on a branch.
While these options are valid, they have their pitfalls. Option 1 sometimes requires drastic, invasive rewrites of the model code to specialize, and torch.cond() is not a comprehensive system for handling data-dependent errors.
As we will see, there are data-dependent errors that do not involve control-flow.
The generally recommended approach is to start with torch._check() calls. While these give the impression of purely being assert statements, they are in fact a system of informing the compiler on properties of symbols.
While a torch._check() call does act as an assertion at runtime, when traced at compile-time, the checked expression is sent to the symbolic shapes subsystem for reasoning, and any symbol properties that follow from the expression being true,
are stored as symbol properties (provided it’s smart enough to infer those properties). So even if unbacked symbols don’t have hints, if we’re able to communicate properties that are generally true for these symbols via
torch._check() calls, we can potentially bypass data-dependent guards without rewriting the offending model code.
For example in the model above, inserting torch._check(a >= 10) would tell the compiler that y + 2 can always be returned, and torch._check(a == 4) tells it to return y * 5.
See what happens when we re-export this model.
class Foo(torch.nn.Module):
def forward(self, x, y):
a = x.item()
torch._check(a >= 10)
torch._check(a <= 60)
if a // 2 >= 5:
return y + 2
else:
return y * 5
inps = (
torch.tensor(32),
torch.randn(4),
)
ep = export(Foo(), inps)

Export succeeds, and note from the range constraints field that u0 takes on a range of [10, 60].
So what information do torch._check() calls actually communicate? This varies as the symbolic shapes subsystem gets smarter, but at a fundamental level, these are generally true:
Equality with non-data-dependent expressions:
torch._check()calls that communicate equalities likeu0 == s0 + 4oru0 == 5.Range refinement: calls that provide lower or upper bounds for symbols, like the above.
Some basic reasoning around more complicated expressions: inserting
torch._check(a < 4)will typically tell the compiler thata >= 4is false. Checks on complex expressions liketorch._check(a ** 2 - 3 * a <= 10)will typically get you past identical guards.
As mentioned previously, torch._check() calls have applicability outside of data-dependent control flow. For example, here’s a model where torch._check() insertion
prevails while manual specialization & torch.cond() do not:
class Foo(torch.nn.Module):
def forward(self, x, y):
a = x.item()
return y[a]
inps = (
torch.tensor(32),
torch.randn(60),
)
try:
export(Foo(), inps)

The following call raised this error:
File "/var/lib/workspace/intermediate_source/torch_export_tutorial.py", line 702, in forward
return y[a]
To fix the error, insert one of the following checks before this call:
1. torch._check((-1)*a > 60)
2. torch._check((-1)*a <= 60)
(These suggested fixes were derived by replacing `u0` with a in -u0 > 60 and its negation.)
The error above occurred when calling torch.export.export. If you would like to view some more information about this error, and get a list of all other errors that may occur in your export call, you can replace your `export()` call with `draft_export()`.
Here is a scenario where torch._check() insertion is required simply to prevent an operation from failing. The export call will fail with
“Could not guard on data-dependent expression -u0 > 60”, implying that the compiler doesn’t know if this is a valid indexing operation -
if the value of x is out-of-bounds for y or not. Here, manual specialization is too prohibitive, and torch.cond() has no place.
Instead, informing the compiler of u0’s range is sufficient:
class Foo(torch.nn.Module):
def forward(self, x, y):
a = x.item()
torch._check(a >= 0)
torch._check(a < y.shape[0])
return y[a]
inps = (
torch.tensor(32),
torch.randn(60),
)
ep = export(Foo(), inps)

Specialized values#
Another category of data-dependent error happens when the program attempts to extract a concrete data-dependent integer/float value while tracing. This looks something like “Could not extract specialized integer from data-dependent expression”, and is analogous to the previous class of errors - if these occur when attempting to evaluate concrete integer/float values, data-dependent guard errors arise with evaluating concrete boolean values.
This error typically occurs when there is an explicit or implicit int() cast on a data-dependent expression. For example, this list comprehension
has a range() call that implicitly does an int() cast on the size of the list:
class Foo(torch.nn.Module):
def forward(self, x, y):
a = x.item()
b = torch.cat([y for y in range(a)], dim=0)
return b + int(a)
inps = (
torch.tensor(32),
torch.randn(60),
)

export(Foo(), inps, strict=False)

The error above occurred when calling torch.export.export. If you would like to view some more information about this error, and get a list of all other errors that may occur in your export call, you can replace your `export()` call with `draft_export()`.
For these errors, some basic options you have are:
Avoid unnecessary
int()cast calls, in this case theint(a)in the return statement.Use
torch._check()calls; unfortunately all you may be able to do in this case is specialize (withtorch._check(a == 60)).Rewrite the offending code at a higher level. For example, the list comprehension is semantically a
repeat()op, which doesn’t involve anint()cast. The following rewrite avoids data-dependent errors:
class Foo(torch.nn.Module):
def forward(self, x, y):
a = x.item()
b = y.unsqueeze(0).repeat(a, 1)
return b + a
inps = (
torch.tensor(32),
torch.randn(60),
)
ep = export(Foo(), inps, strict=False)

Data-dependent errors can be much more involved, and there are many more options in your toolkit to deal with them: torch._check_is_size(), guard_size_oblivious(), or real-tensor tracing, as starters.

or Dealing with GuardOnDataDependentSymNode errors.
Custom Ops#
torch.export can export PyTorch programs with custom operators. Please
refer to this page
on how to author a custom operator in either C++ or Python.
The following is an example of registering a custom operator in python to be
used by torch.export. The important thing to note is that the custom op
must have a FakeTensor kernel.
@torch.library.custom_op("my_custom_library::custom_op", mutates_args={})
def custom_op(x: torch.Tensor) -> torch.Tensor:
print("custom_op called!")
return torch.relu(x)
@custom_op.register_fake
def custom_op_meta(x):
# Returns an empty tensor with the same shape as the expected output
return torch.empty_like(x)
Here is an example of exporting a program with the custom op.
class CustomOpExample(torch.nn.Module):
def forward(self, x):

IR/Decompositions#
The graph produced by torch.export returns a graph containing only
ATen operators, which are the
basic unit of computation in PyTorch. As there are over 3000 ATen operators,
export provides a way to narrow down the operator set used in the graph based
on certain characteristics, creating different IRs.
By default, export produces the most generic IR which contains all ATen
operators, including both functional and non-functional operators. A functional
operator is one that does not contain any mutations or aliasing of the inputs.
You can find a list of all ATen operators
here
and you can inspect if an operator is functional by checking
op._schema.is_mutable, for example:
print(torch.ops.aten.add.Tensor._schema.is_mutable)
print(torch.ops.aten.add_.Tensor._schema.is_mutable)
False
True
This generic IR can be used to train in eager PyTorch Autograd. This IR can be
more explicitly reached through the API torch.export.export_for_training,
which was introduced in PyTorch 2.5, but calling torch.export.export
should produce the same graph as of PyTorch 2.6.

We can then lower this exported program to an operator set which only contains
functional ATen operators through the API run_decompositions, which
decomposes the ATen operators into the ones specified in the decomposition
table, and functionalizes the graph. By specifying an empty set, we’re only
performing functionalization, and does not do any additional decompositions.
This results in an IR which contains ~2000 operators (instead of the 3000
operators above), and is ideal for inference cases.

As we can see, the previously mutable operator,
torch.ops.aten.add_.default has now been replaced with
torch.ops.aten.add.default, a l operator.
We can also further lower this exported program to an operator set which only contains the Core ATen Operator Set, which is a collection of only ~180 operators. This IR is optimal for backends who do not want to reimplement all ATen operators.

We now see that torch.ops.aten.conv2d.default has been decomposed
into torch.ops.aten.convolution.default. This is because convolution
is a more “core” operator, as operations like conv1d and conv2d can be
implemented using the same op.
We can also specify our own decomposition behaviors:
my_decomp_table = torch.export.default_decompositions()
def my_awesome_custom_conv2d_function(x, weight, bias, stride=[1, 1], padding=[0, 0], dilation=[1, 1], groups=1):
return 2 * torch.ops.aten.convolution(x, weight, bias, stride, padding, dilation, False, [0, 0], groups)
my_decomp_table[torch.ops.aten.conv2d.default] = my_awesome_custom_conv2d_function
my_ep = ep_for_training.run_decompositions(my_decomp_table)
print(my_ep.graph)

%b_bn_num_batches_tracked : [num_users=1] = placeholder[target=b_bn_num_batches_tracked]

%mul : [num_users=1] = call_function[target=torch.ops.aten.mul.Tensor](args = (%convolution, 2), kwargs = {})
%add : [num_users=1] = call_function[target=torch.ops.aten.add.Tensor](args = (%b_bn_num_batches_tracked, 1), kwargs = {})

return (getitem_3, getitem_4, add, getitem)
Notice that instead of torch.ops.aten.conv2d.default being decomposed
into torch.ops.aten.convolution.default, it is now decomposed into
torch.ops.aten.convolution.default and torch.ops.aten.mul.Tensor,
which matches our custom decomposition rule.
ExportDB#
torch.export will only ever export a single computation graph from a PyTorch program. Because of this requirement,
there will be Python or PyTorch features that are not compatible with torch.export, which will require users to
rewrite parts of their model code. We have seen examples of this earlier in the tutorial – for example, rewriting
if-statements using cond.
ExportDB is the standard reference that documents
supported and unsupported Python/PyTorch features for torch.export. It is essentially a list a program samples, each
of which represents the usage of one particular Python/PyTorch feature and its interaction with torch.export.
Examples are also tagged by category so that they can be more easily searched.
For example, let’s use ExportDB to get a better understanding of how the predicate works in the cond operator.
We can look at the example called cond_predicate, which has a torch.cond tag. The example code looks like:
def cond_predicate(x):
"""
The conditional statement (aka predicate) passed to ``cond()`` must be one of the following:
- ``torch.Tensor`` with a single element
- boolean expression
NOTE: If the `pred` is test on a dim with batch size < 2, it will be specialized.
"""
pred = x.dim() > 2 and x.shape[2] > 10
return cond(pred, lambda x: x.cos(), lambda y: y.sin(), [x])
More generally, ExportDB can be used as a reference when one of the following occurs:
Before attempting
torch.export, you know ahead of time that your model uses some tricky Python/PyTorch features and you want to know iftorch.exportcovers that feature.When attempting
torch.export, there is a failure and it’s unclear how to work around it.
ExportDB is not exhaustive, but is intended to cover all use cases found in typical PyTorch code. Feel free to reach
out if there is an important Python/PyTorch feature that should be added to ExportDB or supported by torch.export.
Running the Exported Program#
As torch.export is only a graph capturing mechanism, calling the artifact
produced by torch.export eagerly will be equivalent to running the eager
module. To optimize the execution of the Exported Program, we can pass this
exported artifact to backends such as Inductor through torch.compile,
AOTInductor,
or TensorRT.

Conclusion#
We introduced torch.export, the new PyTorch 2.X way to export single computation
graphs from PyTorch programs. In particular, we demonstrate several code modifications
and considerations (control flow ops, constraints, etc.) that need to be made in order to export a graph.
