we found last week that VS does not switch architecture for Nuget installed package. You have to do it manually: |
|
#472 I saw that one and it was not clear to me how to update manually would you please elaborate a bit more? Thanks! |
|
Go to nuget package location and select x86 or x64 folder and add this
reference manually to the project as assembly (not nuget package).

Here is what I did you can correct me whenever I am wrong:
|
|
Also you are not answering my question why is it two different errors if it were for the architecture compatibility issue one of the two should be working shouldn't it? |
|
I just checked and it is working fine with 64-bit Python 3.5. You can only use x64 or x86 corresponding to Python architecture, so can you show full output of |
|
C:\Users\XXXX>python --version I installed the 64 bit python which did not work with either x64 or x86 |
|
Specifically on x64 it's complaining An unhandled exception of type 'System.DllNotFoundException' occurred in Python.Runtime.dll Additional information: Unable to load DLL 'python35': The specified module could not be found. (Exception from HRESULT: 0x8007007E) |
|
Can you install with pip instead of nuget?

Hay, this thing is killing me I would appreciate if you bear with me.
|

Did you add your python to path?
%Python_home% is wrong environment variable, it should be without
underscore.

1. pip install pythonnet-2.3.0-cp35-cp35m-win_amd64.whl
2. add Python.Runtime.dll from
C:\Users\XXX\AppData\Local\Programs\Python\Python35\Lib\site-packages to my
C# application
3. run example again. Exactly same error.

"Installed CPython is reachable by %PATH% or %PYTHONHOME% environment variables." Maybe change the or to and since PYTHON_HOME is added to PATH? It worked, thanks very much! |
|
Pythonhome is needed for embedding python, while python in path is only when starting the Python interpreter. |
|
last question, would python3.6 work with pythonnet-2.3.0-cp35? |
|
You can install for python 3.6 with pip from PyPi:
https://pypi.python.org/pypi/pythonnet/2.3.0
Another thing about pythonhome is that it is only required for python
installation, that is not registered globally on the machine or when
multiple python versions are installed.

Environment
Details
Running Embedding Python in .NET on x86 Py.GIL() triggers the following:
An unhandled exception of type 'System.DllNotFoundException' occurred in Python.Runtime.dll
Additional information: Unable to load DLL 'python35': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
on x64 a different one:
An unhandled exception of type 'System.BadImageFormatException' occurred in mscorlib.dll
Additional information: Could not load file or assembly 'Python.Runtime, Version=2.3.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Searched for the similar issues some are pointing to the Nuget error in switching platforms but if that's the case one of the two should work right?
where python: C:\Users\XXX\AppData\Local\Programs\Python\Python35\python.exe
python --version: Python 3.5.3
%PYTHON_HOME%: C:\Users\XXX\AppData\Local\Programs\Python\Python35
%PYTHONPATH%: C:\Users\XXXX\AppData\Local\Programs\Python\Python35\Lib
The only thing I want to do is to call Python scripts from C# application. It would be great if there is a simple short cut.
