Numpy error when installing raw motion capture data

[ShadowDawg]

I was following the instructions given here. On running

from loco_mujoco.utils.dataset import download_raw_mocap_datasets
download_raw_mocap_datasets()

the following error occurs:

Unexpected exception formatting exception. Falling back to standard exception

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.12 from "c:\Users\shado\OneDrive\Desktop\work\ai-humanoid\.conda\python.exe"
  * The NumPy version is: "1.26.4"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: No module named 'numpy.core._multiarray_umath'

The above exception was the direct cause of the following exception:

My system details - OS: Windows 11 Python version: 3.10.13 (conda) numpy version: 1.26.4

I would appreciate any help regarding this!

Could you try to run this from plain Python rather than IPython?

[ShadowDawg]

Yes, it works from python. Thanks for the help and sorry for the late response!
