Dear professor，
I came across the problem when runing mtag, and the err log file was shown as below.
I will bed truly appreciated fot your help.

Calling ./mtag.py \

It looks like it's likely getting hung up somewhere in the section that starts here. If you put some print statements ("print('SOME TEXT')") and/or log statements ("logging.info('SOME TEXT')") in amongst those lines, it would help narrow down where it's having an issue. For it to be a segmentation fault, though, it implies that it's likely down at the C level in a package like Pandas or Numpy or something.
