load weights require h5py

Question

Im trying to run a keras model,trying to use pre-trained VGGnet- When i run this Command base_model = applications.VGG16(weights='imagenet', include_top=False, input_shape=(img_rows, img_cols, img_channel))

I get this error:

  ``------------------------------------------------------------------

   2567         if 'layer_names' not in f.attrs and 'model_weights' in f:

ImportError: `load_weights` requires h5py.``

I went through some github issues page where a relevant question was asked,but no solutions were given. Any suggestions?

Answer 1

Install h5py:

pip install h5py

Or if using conda:

conda install h5py

Answer 2

technically you need dependencies, such as:

pip install cython
sudo apt-get install libhdf5-dev
pip install h5py

And restart your jupyter notebok.

Answer 3

in the case that "pip install h5py" does not work, and you see something like: "... already satisfied". in python 3 use "pip3 install h5py"/ this will work.

Answer 4

the below steps solved my issue

conda uninstall h5py
pip install h5py
