Hi, while building a PPOConfig for a custom made environment on GPU I keep getting this error despite the fact that I have the package installed in my environment.
→ 278 gpu_list = GPUtil.getGPUs()
279 result = len(gpu_list)
280 elif sys.platform.startswith(“linux”):
NameError: name ‘GPUtil’ is not defined
Hi @maziarg ,
RLlib is not directly based on GPUtil, but ray itself is.
I suspect your code is from
I’m moving this to thread to Ray so you can get help there.
@ClarenceNg From skimming the code, maybe the if branch should rather be entered on
if importlib.util.find_spec("GPUtil") is not None like further up?
Thank you @arturn, I am assuming that I have to wait for @ClarenceNg to check the issue right?
Will be @cade’s responsibility now
I’m not familiar with
find_spec, but you have a reasonable hypothesis @arturn. I think to confirm, could @maziarg run
import importlib; print(importlib.util.find_spec("GPUtil")) from the same environment where the issue occurs to see what truthy value it seems to be returning?
Seems like we should wrap all interactions with
GPUtil behind a single function in that file. Would deduplicate this kind of code and make it easier to test.
