Hi @rubenjacob, I faced the same issue with PPO. So far I solved downgrading tensorflow version from 2.16 to 2.15. Probably something in the compatibility with Ray went wrong with the latest tensorflow update.
I run your reproduction script and it ends without errors. Moreover, printing policy.cur_lr I got "<tf.Variable 'lr:0' shape=() dtype=float32, numpy=0.0005>".
All my tests are done with Python 3.10, but I think it should work even with 3.11.9.

Hi @LorenzoMattia thanks for your reply. I know that TF <= 2.15 works.
I was trying to update my code to Tensorflow 2.16 and Keras 3 but I guess that isn't fully supported yet.
