Issue with 'stacklevel'

[aclong]

I got this error message:

multiprocessing.pool.RemoteTraceback:
"""
Traceback (most recent call last):
  File "/mydir/.conda/envs/transx-converter/lib/python3.6/multiprocessing/pool.py", line 119, in worker

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/mydir/.conda/envs/transx-converter/lib/python3.6/site-packages/transx2gtfs/converter.py", line 258, in convert

I'll check it tomorrow but thought I'd post it here
