"Warning: Not index found and build_index_from_scratch is False"

What you should know first: I am an absolute noob when it comes to ML-models and programming in general.
I searched the internet far and wide, what this error could mean and found nothing, so I was hoping to find answers in this git repo, even years later.

I am trying to analyze LCMS-Data that was originally in .cdf format, but changed to .mzml via OpenChrom.
The LCMS we are using for this project is from Shimadzu (I don't know the exact gen).
There is no problem loading the chromatograms into the application, however only, if you try to parse it with those given, trained models, that you can download via the UI.
I already followed the documentation and tried this out with the example mix.mzml data and everything worked quite well. However, just my LCMS-data won't work. I also tried plotting my LCMS-data and this worked very nicely too. Just the feature detection won't work. Furthermore, if I want to fit too many chromatograms of my LCMS-data, I sometimes also get the following error message additionally to the already stated one:
AttributeError: module 'numpy' has no attribute 'int'. [...]

Okay I found a workaround myself by just changing line 82 in roi.py (in processing_utils) to the following:

run = pymzml.run.Reader(path, use_index = False, build_index_from_scratch = True)

This ignores the index. At least this works for me. I just don't know if it affects anything...
