Fail to read mesh from obj in CentOs

Describe the bug, what’s wrong, and what you expect:

On linux it fails to load obj file while the same loads on Windows. The model is a simple box exported by Ansys tool. If needed I can send the file.

To Reproduce

import pyvista as pv
data = pv.read(file)

Screenshots If applicable, add screenshots to help explain your problem.

System Information: Linux CentOs

No issue with:

import pyvista as pv
data = pv.read('./Model_AllObjs_AllMats.obj')
