I encountered such an error when I was running, can you tell me the reason?

Did someone solve this?

有人解决了吗？

After I tried to use a brand new conda environment, the problem was solved. It may be a problem of relying on the library version. I hope to help you

Hi!

This issue is likely linked to the version of tensorflow that you have installed. Would you mind sharing which version you are using?

Thanks
Kind regards

It should work with at least tensorflow 2.1 and 2.2 by the way.

Upgrading tensorflow worked. Thank you.

[perslev]

You're welcome 👍

I'm using tensorflow 2.3 and I get this error.

Hi @sweta-r! Would you mind trying to fetch the latest version of the repository and re-install the package with pip? Minor changes have been made to the formatting of the hyperparameter file, so I would also suggest you re-run the ut init command to create a new, correctly formatted file.

Let me know if you encounter any issues.
