ImportError: `save_weights` requires h5py. Problem solved

Problem analysis: It is time to use h5py in conjunction with keras or tensorflow to save the model, so you need to install the library, and ensure that the h5py version matches the problem of keras or tensorflow

Problem resolution

Install h5py

pip install h5py

If the error is still reported, it may be that the h5py version matches keras or tensorflow. I installed tensorflow=1.6, and the installation command is as follows

pip install h5py==2.9.0
