ut train error

[adnanhd]

Hi mathias,

I am still working on the reproduction of the u-sleep model using these commands :). I started everything from scratch, cloned the repository, and created a conda environment u-sleep. Thereafter, first I downloaded and prepared the dataset, then, I started training the model.

Here I get the following error, there are also log files that I shared with you below this error window.

/home/aharun/miniconda3/envs/u-sleep/lib/python3.10/site-packages/tensorflow_addons/utils/ensure_tf_install.py:53: UserWarning: Tensorflow Addons supports using Python ops for all Tensorflow versions above or equal to 2.6.0 and strictly below 2.9.0 (nightly versions are not supported).

Some things might work, some things might not.
If you were to encounter a bug, do not file an issue.
If you want to make sure you're using a tested and supported configuration, either change the TensorFlow version or the TensorFlow Addons's version.
You can find the compatibility matrix in TensorFlow Addon's readme:

Is there anything I can do to fix this bug?
thanks in advance

Hi adnan

Sorry for my late reply! Could you please try and update to the latest version of utime (version 1.0.9) and see if you still experience this issue?

Cheers
Mathias
