[Ifeffit] Larix.desktop on Arch Linux AttributeError: 'list' object has no attribute 'shape'

[Matthew Newville]

Hi Cristian,

You tell us you are using a particular Linux distribution. I doubt this matters – if you got as far as Larix running, then the OS-specific or distribution-specific challenges are almost all solved.  But then you also say that you are opening a ".xlsx" data file.  Are you really opening an Excel spreadsheet file?   I can certainly believe that will lead to problems!

In general, when asking about an error reading in a data file,  it is probably a good idea to assume that you should attach an example file that shows the problem.

Hello,

So I recently installed Larch on two different machines running two different distributions of Arch (Manjaro and EndeavourOS). When I am starting Larix.desktop from the terminal and open a .xlsx data file with two columns (energy and intensity), I get the following error:

Traceback (most recent call last):

AttributeError: 'list' object has no attribute 'shape'


I haven't modified any of the respective files at all. This is what the programme came as.
