import d4rl error

[CodingNovice7]

When I just finished installing d4rl, the following error will appear when importing d4rl: "oserror: cannot find mujoco library at / home / NOA /. Mujoco / lib / libmujoco. So. 2.1.1." Later 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. The following errors appear again.:"AttributeError: /home/lyl/.mujoco/mujoco210/bin/libmujoco210.so: undefined symbol: mj_printFormattedModel." How should I solve them?

I met the same issue. Actually, it is a version conflict of dm_control and mujoco_py. The dm_control needs mujoco-2.1.1 by default while mujoco_py only support mujoco210 by now. I fixed the issue temporarily be following steps.

1. pip uninstall d4rl, dm_control, mujoco_py...
2. edit line 17 of setup.py in d4rl source file as 'dm_control @ git+git://github.com/deepmind/dm_control@644d9e0047f68b35a6f8b79e5e8493e2910563af', which is the latest version of dm_control that support mujoco210.
3. pip install -e .

and we are done,

BTW, it is related to https://github.com/rail-berkeley/d4rl/issues/125 and a similar solution was given and discussed in https://github.com/rail-berkeley/d4rl/pull/126.
