I am pretty new with blender, I am trying to build it as a python module, which I successfully managed to do following this link blender-python.

However, this builds the module for python 3.9 but I want to to build it for python 3.7 since I want to incorporate other functionalities which use libraries in python 3.7.

After some research I found this answer and tried that too but I am unable to achieve any success. I would really appreciate if someone can help me on this issue.

Q: How can I build blender as a python module based on Python 3.7?

You have to use a version of Blender that used Python 3.7 as its Python. This will also mean checking out a version of the SVN dependency repo for that version of blender (although I think checking out the tag from the git repo and running make update will do this for you). From the other answer you mentioned: "The Python version requirements are the same with building a regular blender binary (if Blender us using Python3.6 then there is NO WAY to use another version - 2.7/3.2/3.6 will all fail)." I believe this article was written for Blender 2.8, so try doing
git checkout blender-v2.80-release and then make update and see if it'll build.

I := Python 3.9, because the walrus operator is awesome!

  • $\begingroup$ Thanks a lot for your input, I'll take them into consideration and try building again. Reason for using Python3.7 is that, I want to use ML frameworks and some additional libraries which currently does not support future python3.9. However I agree with your suggestion on using python3.9. $\endgroup$ Commented Jul 20, 2021 at 22:02
  • $\begingroup$ Hi Joseph, I have checked out the Blender 2.80 branch, However I am having trouble switching to correct svn branch as I cannot find the on that I need. Do you have any idea where I can find it? $\endgroup$ Commented Jul 25, 2021 at 17:38
