inceptionV3_imagenet .h5 to .pb convertion fails

[ahoquegh]

Hello,
convert.py script failed while I was trying to convert the imagenet trained inceptionV3 model ( downloaded from https://github.com/fchollet/deep-learning-models/releases/download/v0.5/inception_v3_weights_tf_dim_ordering_tf_kernels_notop.h5
Appreciate if you could suggestion solution or workaround
Thanks

Here is the error captured from o/p:
$ ./convert.py inception_v3_weights_tf_dim_ordering_tf_kernels_notop.h5 inception_v3_weights_tf_dim_ordering_tf_kernels_notop.pb

This model has no graph embedded in it. .h5 is a generic format, and in the world of Keras it can be used to store both full models as well as weights alone. In this case, your .h5 has only weights and no graph/model definition. To store a full model based on these weights, you can do this:

First install an old version of keras:

pip install keras==2.0.4 # this appears to be a model compatible with this code

here is a modified script that will generate a complete model:

https://gist.github.com/sleepsonthefloor/f527470b0a38c0f6b2f3aa8908503923

If you run that script, it should yield a file called whole_inception_model.h5

And now you should be able to create your .pb:

docker run -v $PWD:/tmp/ sleepsonthefloor/graphpipe-h5topb:latest  whole_inception_model.h5 whole_inception_model.pb
