Traceback (most recent call last):
File "D:\py\Anaconda3\envs\marlbase\lib\pathlib.py", line 1175, in mkdir
self._accessor.mkdir(self, mode)
OSError: [WinError 123] 文件名、目录名或卷标语法不正确。: 'outputs\lbforaging:Foraging-8x8-2p-3f-v3\ia2c\b5e5d3d5'
Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.

Hey! Could you please describe what you are doing more thoroughly? What file did you run? What is the full error?

I suspect this might be a windows path error, not allowing the use of ":" in the output path name. Perhaps you could replace the output path?

Thank you for your reply. My problem occurs when I execute the command "python run.py +algorithm=ia2c env.name="lbforaging:Foraging-8x8-2p-3f-v3" env.time_limit=25", and I don't know how to modify the path to avoid the error. The previous steps were executed correctly.

yourpath\codebase\marlbase\configs\default.yaml
This file contains:
···
hydra:
run:
dir:outputs/${env.name}/${algorithm.name}/${random:4}
···
Modify ${env.name}. Easiest way is to delete /${env.name}，which is dir: outputs/${algorithm.name}/${random:4}
Then you can run algorisims successfully.
