This seems like something is wrong with your Keras install. Can you try reinstalling in a clean venv from the InstallPackages.py?

[hyybuaa]

@mitchellspryn sorry ,i'm a newer and don't know how to reinstall in a clean env

[hyybuaa]

sorry,i don't use jupyter notebook.I edit it in pychram ,so error

[mitchellspryn]

It sounds like your environment is not set up properly. Please follow the instructions that are specified in the "Prerequisites and Setup" section of the main README page here. This explains in detail how to install anaconda and the dependencies.

Also, the tutorial files are jupyter notebooks. AFAIK, they won't work directly in pycharm unless you convert them to standard python files. Also, I don't know how pycharm interacts with anaconda virtual environments - you're probably better off just using the notebooks. Is there a specific reason you're trying to use pycharm?

[mitchellspryn]

@hyybuaa, were you able to run the notebooks?

[hyybuaa]

@mitchellspryn yes, I can

[mitchellspryn]

Great. I'll close this issue, then. Thanks for confirming!
