Any idea what this error is?

Platform is ubuntu 22.04 on aws graviton3 (arm). d3rlpy: 1.1.0 torch : 1.11.0

I'm not sure why this happens if you installed d3rlpy via anaconda. One possible reason is the incompatible version of numpy. Can you try to downgrade numpy like this? I don't know how to do it for anaconda though.

$ pip install -U numpy==1.19.5
