For example, python3 demo_3d.py fails like this:

[Taichi] mode=release

Hi @r03ert0 Sorry about that and thank you so much for reporting. I'm fixing this and will release v0.5.10 tonight with this issue resolved.

Btw, I did see your post (https://forum.taichi.graphics/t/run-without-gui-installation-problem/77/3) yet I don't have a clear idea how to resolve it. I did google it, and your attempted solution (edit LD_LIBRARY_PATH) seems to be the suggested solution. Not sure why this doesn't work for your case...

Thank you @yuanming-hu! It works all fine now. You and your team are really impressive 🚀 !!
