Cannot launch python script

[VooDisss]

It seems something is wrong with nlopt, so I would need to know which version of nlopt is compatible with this script, otherwise i do not know what the solution is... It's strange that this tool does not get much attention compared to califlower...

py calistar.py

This looks like a broken Cadquery install, nlopt is attempting to be imported by Cadquery. How did you install Cadquery? I recommend pip, it should automatically pull in the dependencies.

For what it's worth, I've got nlopt 2.7.1 on my machine.

Thanks for pointing to the nlopt version. The issue was that python 3.12 and 3.11 does not support nlopt 2.7.1. I had to install python 3.10.11 from here: https://www.python.org/downloads/windows/ Cause i wanted to remain my python3.12 version installed, i went to the folder of python 3.10, launched cmd in that folder, installed cadquery and nlopt2.7.1 using these commands:

**python -m pip install cadquery
python -m pip install nlopt**

Then i went to the folder which contains calistar.py, launched cmd there and wrote command like this:

C:\Users\USERNAME\AppData\Local\Programs\Python\Python310\python.exe calistar.py

and got output with: 1.5707963267948966 1.5707963267948966 -1.5707963267948966 1.5707963267948966 -1.5707963267948966 1.5707963267948966 1.5707963267948966 1.5707963267948966 1.5707963267948966 0.0 3.141592653589793 1.5707963267948966 1.5707963267948966 1.5707963267948966 1.5707963267948966 0.0 3.141592653589793 1.5707963267948966 1.5707963267948966 1.5707963267948966 1.5707963267948966 0.0 3.141592653589793 1.5707963267948966 1.5707963267948966 0.0 0.0 1.5707963267948966 0.0 Traceback (most recent call last): File "E:\ACloud\Random stuff\3dprint\fleur_de_cali-main\calistar.py", line 188, in <module> show_object(result) NameError: name 'show_object' is not defined

[dirtdigger]

Yup, that last one's a bug of sorts. show_object is a command built into Cadquery's editor cq-editor. If you're not using that (e.g. running from the command line) it'll crash like that.

I'll wrap it in a try/except next update. In the meantime, you should be able to comment it out and it'll run fine.

Edit: "it" referring to line 188 which contains "show_object(result)"

If anyone needs to downgrade python to version 3.10.11, you can change the priority of which python version is used by doing so:

1. Go to "edit the system enviroment variables"
2. Press "Enviroment variables"
3. Find "Path" in the System variables field, select it
4. Click "edit"
5. Make sure your direction to python3.10.11 is added, some line must contain "C:\Users\USERNAME\AppData\Local\Programs\Python\Python310"
6. Use the "Move Up" button, to put it above another version of python version, this shifts CMD.exe priority to use python 3.10.11 first, use another only if that one is not found...

After new update and these things i wrote - calistar.py started working for me
