Caffe to keras model AttributeError: type object 'h5py.h5.H5PYConfig' has no attribute '__reduce_cython__'

[alecda573]

Platform : Windows 10

Python version: 3.7.9

Source framework with version: Caffe 1.x
Destination framework with version: keras (tensorflow 1.15)
Pre-trained model path: OpenPose Body 25 https://github.com/CMU-Perceptual-Computing-Lab/openpose

Running scripts:

I have installed this repo through PyPi using
pip install mmdnn

I am trying to convert the model using the following command:
mmconvert --srcFramework caffe --inputWeight pose_iter_584000.caffemodel --inputNetwork pose_deploy.prototxt --dstFramework keras --outputModel base.h5

However I get the following error:

AttributeError: type object 'h5py.h5.H5PYConfig' has no attribute '__reduce_cython__'

I have 2.8 of h5py in my environment

I can remove this error by installing keras 2.3.1 directly in my environment but then it throws the following error:

AttributeError: module 'tensorflow' has no attribute 'placeholder' which is a TF v2.x issue, and can only be bypassed to my knowledge by import tensorflow.compat.v1 and disabling v2 behavior. However, I would rather not have to dig through the source if there is another obvious fix.

I successfully can get the intermediate representation, and I have successfully converted the model to onnx but when I check the ```
onnx model using
onnx.checker.check I get the following bad node:
ValidationError: Node (prelu4_2) has input size 1 not in range [min=2, max=2].

Thank you for your issures, now mmdnn only support tensorflow1.x . And maybe you have wrong tf version

@cookieli my environment had tensorflow1.15 installed and this did not fix the issue....
