Answer 1

1. Go to: Miniconda3\Lib\site-packages or wherever h5py is installed.

2. Delete h5py Folder

3. Delete h5py-2.10.0.dist-info Folder (This might be different if you have a different 4. version).

4. Install h5py again.

   It worked for me after a long search. Finally, I tried to delete it manually and reinstall it. IT WORKED!!!!!

By uninstalling them using cmd, pip, anaconda Some files might stuck and will cause errors even after installing a different version.
