In my case, it seems like upgrading dm_control did the trick, but I have not thoroughly tested if it breaks something else.

pip3 install --upgrade dm_control

Hello,

Thank you for reaching out and sharing the issue you're encountering with Docker while trying to run DreamerV3. The problem you're experiencing is indeed related to the recent major update of Mujoco to versions beyond 3.0.0.

To resolve this, I have updated our project to fix the Mujoco version. This fix is included in the latest commit.

If you continue to face any challenges or have further questions, please don't hesitate to reach out again.
