import d4rl Cannot find MuJoCo library issue

[albert-no]

I am getting OSError : Cannot find MuJoCo library /home/noa/.mujoco/lib/libmujoco.so.2.1.1. issue. I successfully installed d4rl with pip install e . but I am getting this error when importing d4rl. The error message is pasted below.

Had the same error yesterday, for some reason dm_control is looking for the .so file in a wrong path. Eventually I resolved to a brute force approach: I edited the dm_control code (the get_mjlib function) and inserted a hard-coded path to the file in ~/.mujoco/mujoco210/bin/libmujoco210.so.

I did the same thing as you, but there was another error.AttributeError: /home/lyl/.mujoco/mujoco210/bin/libmujoco210.so: undefined symbol: mj_printFormattedModel

Download the newest mujoco from : https://github.com/deepmind/mujoco/releases/tag/2.1.1 and then tar -zxvf it to ~/.mujoco, which works for me!
