Error running fg.fit and fg.save_report

[caroline-kelsey]

Hello! I hope this finds you well. Thank you so much for creating an R based tutorial for specparam. I am more than happy to provide any additional details needed to recreate this code. For reference, I am running R (version 4.3) on a PC computer. Thank you so much for your help.

I am running through the example and am getting stuck at fg.save_report

Here is the line: fg.save_report('EOP_demo', file_path = 'C:/Users/carol/Desktop/EEG/Infancy_Foof/Output')

Here is the error message:

Hey @caroline-kelsey - do you know what version of fooof you have installed? I think that error relates to a change in numpy that has now been addressed in a new version of fooof - so if you are on version 1.0.0 (or older), I think you just need to update to 1.1.0

Can you try updating fooof, by running the following in terminal:
pip install -U fooof

Hopefully that fixes it - let me know if not!
