Can't install the ghhops-server module: rhino3dm has an invalid wheel

This goes along with my other topic where my hops simply doesn’t work with flask for some reason:

What’s going on?

Thanks,

Can you try this again? I pushed the whl with the incorrect directory structure.

I can install it now, thanks, it still creates this problem when trying to use ghhops and flask:

Seems like input_data doesn’t have a value in the ‘0’ position of ["InnerTree"]. Can you try and print input_data to see its structure?

Thanks, please explain if you can - there’s no defined variable called input_data, I made a super simple definition to test:

def math(b):
    if b:
        print(input_data)
        resultmath = 1+2
        return resultmath

The print from inside the definition doesn’t work as it shows me the errors above and again:

Outside the definition it simply gives me a syntax error:

D:\Python\Test\venv\Scripts\python.exe D:\Python\Test\app.py 
  File "D:\Python\Test\app.py", line 25
    print(input_data)
    ^
SyntaxError: invalid syntax

Any updates? I had the exact same error and I don’t know what to do

I deleted Python entirely from my computer, from Path and all, and then reinstalled only one version (Python 3.10), created an entirely new project based on the fresh Python install and that solved it.
