Import CadQuery into Blender with pip #1068

Open lawrence-dubowitz opened 2 years ago

lawrence-dubowitz commented 2 years ago

How would I go about installing CadQuery into Blenders preinstalled python distribution (3.10.2) with pip?

I want to integrate CadQuery into a Blender plugin for parametric modelling with geometry nodes similar to Rhino's Grasshopper.

Thanks in advance!

jmwright commented 2 years ago

I'm not sure how it works with Blender, but in the Godot-Python plugin you use the pip binary that's bundled with the plugin and the package installs into the directory structure of the plugin. So something like /path/to/plugin/pip install cadquery Are there instructions on how to install other PyPi packages in Blender that you can link to?

This is a temporary package while we work on getting the Python wheels onto our main PyPi account, but you can try installing CadQuery with pip install cadquery2 for now.

I'm tagging @roipoussiere on this as well.

lawrence-dubowitz commented 2 years ago

thanks for the quick response!

what other dependencies do I need to install manually? Its complaining that it cant find the module OCP...

The only link I can find that refers to importing external packages can be found here: https://b3d.interplanety.org/en/installing-python-packages-with-pip-in-blender-on-windows-10/

jmwright commented 2 years ago

Doing pip install cadquery2 should have installed the ocp-vtk wheel automatically, but that install process is fairly new, so there could be a bug in this use case. You could try pip install ocp-vtk separately to see what happens.

lawrence-dubowitz commented 2 years ago

Unfortunately no luck installing ocp-vtk. I'll continue trying to get it to work and I'll post the solution if I manage to get it working.

jmwright commented 2 years ago

@lawrence-dubowitz It seems like there might be an issue with the ocp-vtk wheel in Windows 10, so it will take time to fix that. You could try creating an Anaconda environment and then launching Blender from the command line with that environment activated. I'm not sure that will work for Blender, but I used to run Godot that way in Linux.

lawrence-dubowitz commented 2 years ago

Thanks, I'll give it a try and let you know how it goes...

@lawrence-dubowitz The following should work as a way to test (it worked for me on Windows 11 and Python 3.8), and the community is working on a permanent solution that works seamlessly with PyPi.

If Blender is running Python 3.8:

pip install https://github.com/jmwright/ocp-build-system/releases/download/7.5.3/ocp_vtk-7.5.3.0-cp38-cp38-win_amd64.whl 'git+https://github.com/CadQuery/cadquery' ezdxf multimethod nlopt nptyping typish

If Blender is running Python 3.9:

pip install https://github.com/jmwright/ocp-build-system/releases/download/7.5.3/ocp_vtk-7.5.3.0-cp39-cp39-win_amd64.whl 'git+https://github.com/CadQuery/cadquery' ezdxf multimethod nlopt nptyping typish

If Blender is running Python 3.10:

pip install https://github.com/jmwright/ocp-build-system/releases/download/7.5.3/ocp_vtk-7.5.3.0-cp310-cp310-win_amd64.whl 'git+https://github.com/CadQuery/cadquery' ezdxf multimethod nlopt nptyping typish

Wonderful, thank you very much!

I will give it a try as soon as I get a chance...

@lawrence-dubowitz We'll have a release on PyPi sometime in the near future, but you can now install the latest CadQuery commit via pip from the git repo. You'll need a fairly recent version of pip first.

python3 -m pip install --upgrade pip

And then you can run this line.

pip install git+https://github.com/CadQuery/cadquery.git

Let us know if this works in Blender.

The installation works for me if I force pip to run with the bundled version of Python.

"C:\Program Files\Blender Foundation\Blender 3.1\3.1\python\bin\python.exe" -m pip install git+https://github.com/CadQuery/cadquery.git

I didn't even upgrade pip since it was already at version 21, which is good enough to install our packages.

"C:\Program Files\Blender Foundation\Blender 3.1\3.1\python\bin\python.exe" -m pip --version

There were a couple of warnings during the install, but they didn't keep CadQuery from working. I was able to do import cadquery after running python.exe to get the REPL.

jmwright commented 2 years ago

@lawrence-dubowitz Following up on the last comment. Are you running the command from cmd or PowerShell? I ran mine from cmd, and although I didn't run it in administrator mode, that might be worth a try.

I show the same Python version and platform information on my Windows system that you have, so I expect there's something minor that is still keeping this from working.

lawrence-dubowitz commented 2 years ago

Thanks, I'm still struggling to get it working with cmd (also with admin privileges), but at least I know that it's working on your side, so it must be something on my side. I will persist and update the thread once I find out what's going on.

Everything seems to be installing correctly, but I get the following error when running 'import cadquery' inside the Blender REPL:

Is there anything special about your Blender installation? What's your full Blender version number? I installed it this morning on a Windows system that's never had Blender installed before. I downloaded it from here (version 3.1.2). You could start the Python REPL and try the following just to see if at least OCP is working: from OCP import *. If OCP is not installed, you can do pip.exe install cadquery-ocp.

You could also try pip.exe install numpy --upgrade but I don't know if that will break other things in your Blender install. Try at your own risk.
