I'm having the same problem and according to the comments in my question "Python 3.12 has removed PRECALL from its bytecode instructions, so it's likely that the handcalcs package needs an update."

Thanks for the response!

[connorferster]

Agreed. @eriknw it seems that there was a Python API breaking change affecting innerscope.

My bad for not testing the 3.12 release candidate. Should have seen it coming because of all the speed improvements planned for each upcoming Python release.

[connorferster]

Thanks @raianerosa @MJFraker for raising this issue

[eriknw]

My bad for being slow! Been traveling too much... I'll try to get to this soon even if it's just a workaround to make 3.12 work.

I am facing the same issue while import handcalcs.render

[rwaltera]

Same problem, any updates regarding this topic?

[eriknw]

Try updating to the latest innerscope. I just created a new release (0.7.0) that should hopefully resolve this issue.

I'm sorry for the delay! I've had lots of, uh, "adventures" lately, and I updated innerscope to try to avoid issues like this in the future.

[rwaltera]

This seems to work for me, thank you :)
