ZeroDivisionError in evaluate.py #278
Description
This is the error I get when trying to run xqrs detection algorithm from Google Colab as well locally.
I have used demo.ipynb from the repo itself.
/usr/local/lib/python3.6/dist-packages/wfdb/processing/evaluate.py in _calc_stats(self)
118 # No tn attribute
119
--> 120 self.sensitivity = float(self.tp) / float(self.tp + self.fn)
121 self.positive_predictivity = float(self.tp) / self.n_test
122
ZeroDivisionError: float division by zero
The error seems very weird in the sense that even when I comment the particular line, the error still shows in the same line.

Hey @pranavchat14, thanks for the comment! Can you post some more details to recreate this issue? I can't seem to reproduce this error using the current version of
demo.ipynb.pranavchat14 commentedon Apr 5, 2021
Thanks for the response.
Here is the link to the cell from my copy of demo.ipynb. Hope this helps in reproduction of error.

Thanks for the extra info! The only difference is the file
/content/tmp_dl_dir/0001instead ofsample-data/100... what are the contents of that file?fix: guard against ZeroDivisionError in Comparitor._calc_stats
