kinet2pcb module issue

[Lakroft]

Sorry for bothering again, this time I was trying to generate PCB directly from python code using generate_pcb() command mentioned in this book: https://shanemmattner.github.io/skidl_jupyter_book/chapter1/02_basic_usage.html
Warning message says kinet2pcb is missing though it already installed. When I try to import kinet2pcb directly into python shell it gives "No module named 'pcbnew'" error.
I've found pcbnew.py in KiCad dir and added to PYTHONPATH, then error changed to " DLL load failed while importing _pcbnew: Module not found" and on this point I'm out of ideas how it can be fixed.

led.py code the same like in this discussion: #211 with only one change
generate_pcb()
instead of
generate_netlist()

Issue present both on Windows and Mac machines.

Thank you.

I'll take a look at this. I'll have to setup a Windows VM. It looks like you're running KiCad 6?

I think the easiest thing to do is use the Python executable bundled with KiCad. The following is what I did for KiCad 6 running on a Windows 10 VM.

1. Prepend the KiCad Python executable to your path:
   set Path=C:\Program Files\KiCad\6.0\bin;%Path%

2. Next, install SKiDL. The KiCad 6 executables don't include pip, but the pip module is included so use:
   python -m pip install skidl

3. Next, modify the led.py program a bit to point to the directories where the symbols and footprints are:

from skidl import *

# Tell SKiDL where the symbol libraries are.
lib_search_paths['kicad'].append('C:/Program Files/KiCad/6.0/share/kicad/symbols')

anodes = Bus('a', 6)
cathodes = Bus('k', 16)

led = Part('Device', 'D', footprint='Diode_SMD:D_0201_0603Metric', dest=TEMPLATE)

for a in anodes[1:4]:
    for k in cathodes[1:15]:
        led()['A', 'K'] += a, k

for i in range(2,6):
    for k in cathodes[i:i+10:5]:
        led()['A', 'K'] += anodes[5], k

ERC()

# Tell kinet2pcb where the footprint libraries are.
generate_pcb(fp_libs='C:/Program Files/KiCad/6.0/share/kicad/footprints')

4. Finally, run the program:
   python led.py

This should create a led.kicad_pcb file. I opened it with PCBNEW and it appeared to be correct.

Thanks, this worked, I've added a screenshot of generated pcb.
Eventually I've created a separete alias kipy for kicad's python to keep my system's python as default.

BTW looks like kicad's python pooled KICAD_SYMBOL_DIR so line lib_search_paths['kicad'].append('C:/Program Files/KiCad/6.0/share/kicad/symbols') is not nesessery, only the footprint. May be it also could be configured via env var?
