Anaconda VTK install missing VTK module?

Question

Win 10, x64, Python 3.6.6 & Python 2.7.12 (I tried the code in both), IPython 6.1.0

So far I am only able to run VTK projects using Visual Studio in C++ but would like the ease of using an interpreted language for development. So I installed the latest VTK via the Anaconda command prompt, conda install -c anaconda vtk

No problems everything updated & superseded as necessary. So I tried out a trial program from the Python examples only to get...

ModuleNotFoundError: No module named 'vtk'

I added C:\\Program Files (x86)\\Microsoft Visual Studio\\Shared\\Anaconda3_64\\pkgs\\vtk-8.1.0-py36he6bbf13_201\\Lib\\site-packages\\vtk to my PYTHONPATH in Spyder but I still get the same error.

Any idea why IPython cant see the vtk library?

EDIT: VTK shows up as an installed library when I type conda list at the command line

Answer 1

The following worked for me. Make sure to use the Anaconda Prompt .

# Create a new conda environment mypy3env and install vtk.
conda create -n "mypy3env" python=3
conda activate "mypy3env"
conda install -c conda-forge vtk
# Verify that python3 from Anaconda is used!
where python
python --version
# Test if vtk installation was successful
python -c "import vtk; print(vtk.vtkVersion.GetVTKVersion())"

See also the comments here to verify the Anaconda installation.

I tried to create a new environment and the vtk module works for Python version 3.6. When using a newer version of Python the vtk module cannot be loaded Exception has occurred: ModuleNotFoundError No module named 'vtkmodules.vtkCommonCore' (I don't know why).

conda create --name MyEnv python=3.6
conda activate MyEnv
pip install vtk
