Failed to rendering the metadrive environment

[guanjiayi]

I encountered an error when using env.render() to render the MetaDrive environment. Have you successfully visualized the 9 environments in DSRL before? If so, could you provide the versions of Panda and Panda3D you used?

Error message:

Hi @guanjiayi, the panda3d version we are using is 1.10.8, you may find our MetaDrive version (adopted from v0.2.6.0) in this repo.

Hi @guanjiayi, thank you for raising the issue, we provide a detailed example script which now support modifying the config of Metadrive env.

Besides, for the third-person view rendering part, our original dirty version of Metadrive simulator misses a few logo assets, so we also update the metadrive_clean repo. You can simply re-run the following command in the DSRL repo to fix the third-person view rendering bug:

pip3 install -e .[metadrive]
