thx for the patience. I'm not very familiar with python and I am trying to use a tabulate import but get errors.

Traceback (most recent call last): File "\CheckObejctSize.py", line 5, in ModuleNotFoundError: No module named 'tabulate' Error: Python script failed, check the message in the system console

I've read a whole bunch of threads on what to do, but none have helped. I was going to use the blender/pip to add tabulate but I can't seem to even find pip.

I found a thread that suggested:

import ensurepip ensurepip.bootstrap() pybin = bpy.app.binary_path_python subprocess.check_call([pybin, '-m', 'pip', 'install', 'tabulate'])

which produced Defaulting to user installation because normal site-packages is not writeable Looking in links: c:\Users\Jon\AppData\Local\Temp\tmp99hzlnij Requirement already satisfied: setuptools in c:\program files\blender foundation\blender 3.0\3.0\python\lib\site-packages (57.4.0) Requirement already satisfied: pip in c:\program files\blender foundation\blender 3.0\3.0\python\lib\site-packages (21.2.3) Traceback (most recent call last): File "\CheckObejctSize.py", line 10, in AttributeError: 'bpy.app' object has no attribute 'binary_path_python' Error: Python script failed, check the message in the system console

Why can't I find pip when it seems that it's already there and how can I get tabulate import working in Blender 3.0 scripting?

Convoluted but I got it to work:

  • Download the get-pip.py file from the web. https://bootstrap.pypa.io/get-pip.py
  • Place it in ...Blender Foundation\Blender 3.0\3.0\python\bin
  • Run Blender Foundation\Blender 3.0\3.0\python> .\bin\python.exe ./bin/get-pip.py

You will see:

  • This will have created a Scripts directory, now I can use pip3 to install
  • Blender Foundation\Blender 3.0\3.0\python> ./Scripts/pip3 install tabulate

With Subsequent Blender upgrades I ran into problems again, and now I have this script which has been working
