ImportError:'save_weights' requires h5py

Question

When I save weights during training my CNN model using keras, it says ImportError:'save_weights' requires h5py, but I have already installed h5py.

I would greatly appreciate if someone could explain how to fix this issue.

Answer 1

I was getting the same error as you. I installed all the requirements listed here: https://github.com/fchollet/keras/issues/3426

Finally just needed to reboot and it started working.

Answer 2

Just install necessary packages

sudo apt-get install libhdf5-dev

pip install h5py

Answer 3

If you are using windows and python IDE, open cmd and input following commands:

pip install h5py

pip install cython

I hope it helps.
