Did you install making it editable? This gave me the same problem. In other words, this doesn’t work

pip install -e <path_to_dm_control>

while this does work

pip install <path_to_dm_control>

I tend to always use the former when trying out new libraries, so I can edit them and see how they work. However, if you make the library editable, it doesn’t seem to generate the needed mjbindings.

This happens if you “pip install” but then try to import the module form the github source dir. change to some other path than the github checkout and it will work.
