install failure

[marooncn]

Hi, I install the package according to the instructions and when I run
pip3 install -U 'mujoco-py<1.50.2,>=1.50.1'
it reports

You appear to be missing MuJoCo. We expected to find the file here: /root/.mujoco/mjpro150

This package only provides python bindings, the library must be installed separately.

Please follow the instructions on the README to install MuJoCo

  https://github.com/openai/mujoco-py#install-mujoco

Which can be downloaded from the website

  https://www.roboti.us/index.html

But I have downloaded mjpro150_linux.zip and unzipped the directory into ~/.mujoco/mjpro150, and I added the following in the .bashrc as someone suggested,
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:home/maroon/.mujoco/mjpro150/bin
but the error is still not gone.

later on, I compile the package form source, it can be successful, but when I
import mujoco_py
there is another error

ImportError: cannot import name 'pythran_is_numpy_func_supported'

How can I solve it?

[machinaut]

@marooncn From the text of the error, it says where you should install :

You appear to be missing MuJoCo. We expected to find the file here: /root/.mujoco/mjpro150

This is the proper install location for the root user on a linux machine. It is the same as ~/.mujoco/mjpro150 for the root user.

Are you trying to install the package as a root user or as a different user?

[machinaut]

@marooncn could you post the full error, and the output of python --version and pip freeze for installing it from source?

[marooncn]

@machinaut Thanks for your response, the full error:

The pythran issue looks like this one cython/cython#2680

It looks like that person tried downgrading to cython 0.28.5
