    from pyvista.plotting import *
  File "C:\Users\DUVAN PACHECO\AppData\Roaming\Python\Python38\site-packages\pyvista\plotting\__init__.py", line 5, in <module>
    from .export_vtkjs import export_plotter_vtkjs, get_vtkjs_url
  File "C:\Users\DUVAN PACHECO\AppData\Roaming\Python\Python38\site-packages\pyvista\plotting\export_vtkjs.py", line 55, in <module>        
    import vtk
ModuleNotFoundError: No module named 'vtk'

any ideas?, I am using python 3.8.6

Answer 1

You can go on PyPi and find the correct installing command for VTK. Here is the link: PyPi

Answer 2

What is the error you're experiencing when trying to install the module? We cannot help you if you do not include it.

This command should work: pip install vtk

If not, I would recommend researching the error it is giving you.

Answer 3

This error means that you do not have that module installed. You can install it using

pip install vtk

Answer 4

I'd verify that your install of Python is 64-bit. See https://stackoverflow.com/a/10966396/3369879

When running python you should see something like [MSC v.1500 64 bit (AMD64)] , where 64 bit (AMD64) indicates you're running 64-bit Python.

Reason why I say this is because VTK only has Python 64-bit wheels and it's common in Windows to accidentally download and install Python 32-bit. This is why you're getting:

ERROR: Could not find a version that satisfies the requirement vtk

It's because there are no VTK wheels for 32-bit Python.
