I am trying to install mujuco onto my linux laptop and everything works until I try to import it into a python file. When I try to import it/run a python script that already has mujuco in it I get the following errors:

Import error. Trying to rebuild mujoco_py.

I have gcc 11.0.2 installed and I'm using python3.8 in my virtual environment. Here are my exact steps https://docs.google.com/document/d/1eBvfKoczKmImUgoGMbqypODBXmI1bD91/edit
Everything works accordingly until the very last step where I try to run an actual python module
I really don't know why this is happening and I've tried just about everything on the internet. I would really appreciate it if someone can help.
                What does "install mujuco" mean? On Linux something gets installed by compiling and building from source or installing your Linux distribution's pre-compiled and pre-built package. Attempting to download some random binary, from somewhere, always ends in tears.

                I've tried just about everything on the internet. Most of the stuff you'll find on the Internet won't help and some of it is downright disgusting.

                Hi, when I say install mujuco I meant following these exact steps and attempting to install its packages github.com/openai/mujoco-py

                "Download binaries"? That's pretty much it, see my first comment. Don't believe everything you read on the Internet. Unless your Linux distribution is the exact same one that was used to build those binaries, this will end in tears. You'll need to go back to the source code for mujoco, and build it directly from source.

Where does /home/daniel/miniconda3/envs/mujoco_py/lib/libstdc++.so.6 come from? Something bundles a version of libstdc++.so.6 which is older than your system version, and other system libraries depend on the newer version. You should be able to fix this issue by just deleting the file in your home directory.
                HI! I wish I could give this a million thumbs up but my reputation is not high enough. It worked, thank you so much. How did you know with so much confidence that just deleting that random file would fix this issue? Absolutely flabbergasted. Thanks again

                That trick saved me a ton of time. I don't know why Anaconda is copying the file. But hey, I got it fixed and that's what counts.
