ModuleNotFoundError No module named stl

Question

Hi Guys,

I am trying to create and save an STL file with a cube and I cannot import the mesh module for some reason. It is showing me the below error.

from stl import mesh
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-ff307699c9dc> in <module>
----> 1 from stl import mesh
ModuleNotFoundError: No module named 'stl'

How can I solve this error?

Hi@akhtar,

I had the same problem when installing stl. You need to install numpy-stl module in your system. You can use the below-given command.

$ pip install numpy-stl
