How severe does this issue affect your experience of using Ray?
- Medium: It contributes to significant difficulty to complete my task, but I can work around it.
Hi everyone,
I’m still an RLlib newbie. I’m running a multi-agent environment using RLlib 2.0.0, and I get this warning:
/home/ramrachum/.venvs/ray_env/lib/python3.10/site-packages/ray/rllib/models/tf/misc.py:17: RuntimeWarning: divide by zero encountered in divide
out *= std / np.sqrt(np.square(out).sum(axis=0, keepdims=True))
I understand that NumPy is dividing a matrix by another matrix, and since some of the values of the second matrix are zero, the result has inf
in it.
Is this something that you encountered while using RLlib? I’m noticing that the performance of my agents in this experiment is abysmal, and I’m wondering whether it’s caused by this issue.
What can I do about this?
Thanks for your help,
Ram Rachum.
