when I convert my own tensorflow model to IR file, there is a problem happens , Can anyone help me figure it out?
Thanks!

Hi @jackchinor ,
If you follow the Meta File Graph Visualization here, you can probably visualize your graph.

If the batchnorm layer is like this, then it can be easily converted.

However, if the batchnorm layer is like this, it needs more steps.

That is because the mmdnn uses the input information to build the graph.

For the first type, its input is like this:
image

In contrast, for the second type, its input is like this
image

I think that is why AttributeError: 'NoneType' object has no attribute 'name' .

In this situation, if there is a is_training parameter and set it to False and then reload and dump the model, this might reduce the second type to the first type of batchnorm.

Hi @JiahaoYao ,
I also encountered the same problem. Could you please share some sample codes of the solution you mentioned above? I'm a newbie in tensorflow. Really appreciate your help!

Hi, @JiahaoYao , @jackchinor , @criminalking
I have met almost the same problem, could you tell me how to solve it?

  File "c:\users\qjhs\appdata\local\programs\python\python36\lib\site-packages\mmdnn\conversion\tensorflow\tensorflow_parser.py", line 420, in gen_IR
    func(current_node)
  File "c:\users\qjhs\appdata\local\programs\python\python36\lib\site-packages\mmdnn\conversion\tensorflow\tensorflow_parser.py", line 810, in rename_FusedBatchNorm
    self.set_weight(source_node.name, 'mean', self.ckpt_data[mean.name])
AttributeError: 'NoneType' object has no attribute 'name'

Thank you
