Hello,
It seems like the error is related to the rendering of DMC (DeepMind Control). You might find a solution by referring to this issue on GitHub. It could be beneficial in resolving the problem you encountered.
Hi, I tried to train the example on DMC Vision but got the following error:
python3 dreamer.py --configs dmc_vision --task dmc_walker_walk --logdir ./logdir/dmc_walker_walk Logdir logdir/dmc_walker_walk Create envs. libEGL warning: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
