ModuleNotFoundError: No module named “legged_gym” #3

Open lupinjia opened 3 months ago

lupinjia commented 3 months ago

Background

I followed the doc to configure the example, but encountered ModuleNotFoundError: No module named “legged_gym” as I tried to run python3 train.py --task=go2.

Analysis

I doublechecked the sys.path.append() line and ensured that I put my local path of unitree_rl_gym/legged_gym, but it still threw this error. I'm not sure if this is only my case.

I referred to legged_gym, rearranged the file structure and added a setup.py. After pip install -e, the code could run normally.

The file structure is as follows:

|—— legged_gym
    |—— envs
    |—— scripts
    |—— utils
|—— resources
|—— setup.py

By the way, I think the version of rsl_rl(1.0.2) should be noted in the doc, cauz the newer version is not compatible with this repo

well, there is a simple way to solve this problem. First, I run python train.py --task=go2 instead of python3 train.py --task=go2 in unitree_rl_gym/legged_gym. After that, it reported an error saying that the go2 task is not registered. Then, I just simply copy unitree_rl_gym/legged_gym/envs/go2 to legged_gym/legged_gym/envs/and unitree_rl_gym/resources/robots/go2 to legged_gym/resources/robots/ and succeed.
