Hi,

I would like to use panelui. linuxcnc.org/docs/devel/html/gui/panelui.html
But already the start of the demo fails.

What am I doing wrong?

Linuxcnc 2.9, Debian 9

The sim works from a RIP development environment.
I'll test an installed version soon.

I tried on debian and it worked for me...
Can you tell me more about your system and how did you get linuxcnc on it?

From the error report:
ImportError: No module named pyui
Twice.
It should be in :
cnc@shop:~$ whereis pyui
pyui: /usr/bin/pyui
It is not a stand alone package, so i do not know what to install to get it.

i have installed debian stretch using this iso:
cdimage.debian.org/cdimage/archive/9.12.....0-amd64-netinst.iso

I installed LinuxCNC following these instructions:
buildbot.linuxcnc.org/

These are the sources:
deb buildbot.linuxcnc.org/ stretch master-rtpreempt
deb-src buildbot.linuxcnc.org/ stretch master-rtpreempt

sudo apt-get install linuxcnc-uspace
sudo apt-get install linuxcnc-uspace-dev

Everything ist up-to-date


I tested it on two machines:
One is a virtual machine (VirtualBox). See linuxcnc.error in first post.
The other on is my real machine. Same result. See linuxcnc.error attached this post.

That is a Python issue, not a LinuxCNC issue.
That should be packaged with something Python related
Some info here, a bit outdated, but might give a clue

i tried LinuxCNC 2.8 in a virtual machine: sim starts without error.

I compared the files:
/usr/lib/python2.7/dist-packages/pyui/__init__.py and /usr/lib/python2.7/dist-packages/pyui/master.py between 2.8 and 2.9
and found some differences.

__init__.py 2.8:
from pyui import master
__init__.py 2.9:
from .pyui import master


master.py 2.8:
from pyui import widgets as WIDGETS
from pyui import commands

master.py 2.9:
from .pyui import widgets as WIDGETS
from .pyui import commands


i changed the entries .pyui to pyui and now i can start the sim in 2.9

Unfortunately this work around only works until the next apt-get upgrade
I hope this will be fixed in the master sometime

I see the change to .pyui was made durin the python3 transition.
I'm not sure why it was done. I'll inquire.
