The number of lines is odd

[Raffael1998]

Hi, I'm having an error when running this code :

import stltovoxel
iges_file_path = r'..\data\3D-file\Hood-inner2-Output.stl'
stltovoxel.convert_file(iges_file_path, 'output.png')

First I'm getting several warnings:
[Warning] The number of lines is odd
and the process doesn't finish :

[21](file:///C:/Users/Raffael%20GROS/dieface_design/.venv/Lib/site-packages/stltovoxel/convert.py:21) for mesh_ind, org_mesh in enumerate(meshes):

     [43](file:///C:/Users/Raffael%20GROS/dieface_design/.venv/Lib/site-packages/stltovoxel/perimeter.py:43) yi = 0

ValueError: min() iterable argument is empty

Do you know why ? My stl file is fine, I can display it no problem in a stl viewer online for example.
Thanks.

Hi Rafel,
I encountered this issue while writing #62. Could you try again with the new code?
If the issue persists, would you be able to share an STL and command line arguments that reproduce the issue so I can debug?
Thanks,
Christian
