Error during V2 Install

[eiteldo]

Dear all,
I am currently running LG4X and want to use V2 from now on. However, after installing all packages and running main.py, I get the following error:

Traceback (most recent call last):
  File "/Users/dominik/LG4X-V2/Python/main.py", line 3530, in <module>

    raise NoSectionError(section) from None
configparser.NoSectionError: No section: 'GUI'

Can anyone help with this? I am not getting this error with LG4X V1.
Best regards

Thank you for your feedback! The problem was already solved on the experimental branch two_window. If you are interested in further details, you can read more here.

However, I totally forgot to push the fix to the master-branch too. It should be fixed by #fe6e398.

Please let me know, if everything works fine! Your feedback is appreciated and feel free to contribute!

Kind regards,
Julian

PS. I will attend a conference and afterwards be on holidays for the next two weeks, therefore it might take some time before I am able to fix bugs :)

Do LG4X V1 and V2 work on Mac M1 or silicon chips?

[Julian-Hochhaus]

I do not use MacOS, therefore I can't say for sure. However, the software itself is not too hardware heavy, as long as your PC supports the PyQt5 package (used for the GUI) and has python installed, it should run in general.
But I know that there are users working on MacOS, however I don't know their hardware specs.

Thanks for your reply!! i was confused as LG4X-V1 was working on my mac (python3 main.py), while V2 was stuck with the errors:

The above exception was the direct cause of the following exception:

[Julian-Hochhaus]

The reason is that the used style for plotting is not available in your matplotlib installation. Honestly, I can only guess that it may be caused by an outdated matplotlib version in your installation.
In the main.py file, you are able to change the style used. (l.60 is relevant here)
In matplotlib 3.6, seaborn styles were renamed.
In LG4X-V1, the old naming convention was used (compare l.23 in main.py LG4X-V1 style.use('seaborn-pastel')
LG4X-V2 uses the new naming convention (since matplotlib 3.8.0, the old style naming is deprecated)

So you should probably either update your matplotlib installation or change (l.60 in main.py) to use styles in the old naming convention.
You can get a list of available style names of your installation by printing style.available in the IPython Terminal as described here.
