Problem loading geometries with trimesh

[wi0712]

I am trying to use trimesh to load geometries and analyze them, but I simply can not get python/ trimesh to load them at all.
I´ve tried both .obj and .stl formats. Both not working.

import trimesh

def load_and_inspect_stl(file_path):
        mesh = trimesh.load(file_path)
  
input_file = r"C:\Users\willy\desktop\part1.stl"

load_and_inspect_stl(input_file)

Error:
  File ~\anaconda3\Lib\site-packages\numpy\core\fromnumeric.py:2684 in ptp
    return _methods._ptp(a, axis=axis, out=out, **kwargs)

  File ~\anaconda3\Lib\site-packages\numpy\core\_methods.py:220 in _ptp
    umr_maximum(a, axis, None, out, keepdims),

TypeError: '_NoValueType' object cannot be interpreted as an integer

I have no idea, what´s meant by this error or where to find this '_NoValueType' object

I can open the files using meshlab or paint3D. I´ve updated trimesh to the latest version.
I have no idea what I should do to solve this.

I'm also using Anaconda: your snippet works well for me (i used 2 different STL files, so i'm wondering if:

• is your STL file correct?
  
• how have you installed trimesh? from the conda-forge?

I´m sure my files are fine.
I installed trimesh using the pip command in anaconda prompt. Could this be the problem?

I do not use pip with Anaconca, but rather i open a "conda prompt" and type:
conda update --all --yes
conda install conda-forge::trimesh

(conda prompt from Windows start menu -> Anaconda (64 bits) -> Anaconda prompt)

I suggest you to uninstall trimesh from pip and to reinstall from conda prompt
