Errors using --processes parameter

[sonhospa]

Hello Buran and Gribouillis,

thank you for your help. I hope adding a "New Reply" is the right way here, as I couldn't see an individual reply button.

Buran, I used the command line exactly as provided in the quote above (just my own path instead of the sample path). Only after this attempt failed, as an alternative experiment, I changed the Python script (bagit.py) where the equal sign is part of several Python commands, and that's where I changed "processes=1" into "processes=4". You could see that in the link I provided to Github.

Now the errors:
a) First attempt before changing the script: "bagit.py --processes 4 path\to\bag"

Error:
2020-07-01 14:34:35,122 - INFO - Creating bag for directory E:\bagit-master\test-data\loc

Traceback (most recent call last):
  File "C:\Users\Michael\AppData\Local\Programs\Python\Python37\lib\site-packages\pkg_resources\_vendor\packaging\requirements.py", line 90, in __init__
    req = REQUIREMENT.parseString(requirement_string)
  File "C:\Users\Michael\AppData\Local\Programs\Python\Python37\lib\site-packages\pkg_resources\_vendor\pyparsing.py", line 1654, in parseString

    loc, tokens = self._parse( instring, 0 )

This is only a small part, because the error messages run endlessly (i.e. hours!). I interrupted the process after a few seconds and have a file of 7000 lines already.

b) Second attempt: Changes to the script (at 4 positions) from "processes=1" to "processes=4" and rename it. Command: "bagitprocesses4.py path\to\bag"

Error:
I couldn't reproduce the error now!

BUT: After all the files were moved to a particular 'data' direcory correctly and writing the first text files correctly, there's only one process used. The relevant part of the output is (first 6,000 lines and all the following lines left out, I marked the message):

2020-07-01 15:08:16,983 - INFO - Generating manifest lines for file data/reel_08.000046.jpg

So it seems the attempt to change didn't result in errors like using the CLI command, but also didn't change the number of processes and was therefore obsolete.

Is that information helping?
