setting up cadquery and python and getting some errors.

[purushothamanmunusamy]

Just starting with cadquery and python and getting some errors.

Traceback (most recent call last):
  File "C:\Users\info\PycharmProjects\pythonProject2\main.py", line 1, in <module>
    import cadquery as cq
  File "C:\Users\info\PycharmProjects\pythonProject2\venv\lib\site-packages\cadquery\__init__.py", line 11, in <module>
    from .occ_impl.shapes import (
  File "C:\Users\info\PycharmProjects\pythonProject2\venv\lib\site-packages\cadquery\occ_impl\shapes.py", line 19, in <module>
    from vtkmodules.vtkCommonDataModel import vtkPolyData
ModuleNotFoundError: No module named 'vtkmodules.vtkCommonDataModel

my code is

import cadquery as cq
from cadquery.vis import show_object

height = 60.0
width = 80.0
thickness = 10.0

# make the base
result = cq.Workplane("XY").box(height, width, thickness)

# Render the solid
show_object(result)

Versions am using in Pycharm (installed via packages) :
numpy 2.1.1
cadquery 2.4.0

Do i need cq editor to view the screen? i didn't install it.

Any help is appreciated.

Thank you,
Purus.

i understand that i needed vtk lib and installed the same.

now i get this error after installing vtk.

2024-09-11 04:38:39.729 ( 1.840s) [DF028C248740CB57]vtkDemandDrivenPipeline:677 ERR| vtkCompositeDataPipeline (000001A3AC1E64D0): Input port 0 of algorithm vtkTriangleFilter (000001A3A3320F10) has 0 connections but is not optional.

I see a blank screen without 3d model on screen but i should see a box as per the code. Please help.

@purushothamanmunusamy Did you install recently via pip? There may be an issue with the VTK packages.

You can try pip uninstall cadquery_vtk and then pip install cadquery-ocp==7.7.2.0 to see if that fixes the problem?

It worked.

You are awesome.

Thank you so much.
