New submission from Miro Hrončok <[email protected]>:
Recently I've been debugging a very nasty bug report that looked like this:
Traceback (most recent call last):
File "/usr/bin/jupyter-notebook", line 5, in <module>
from notebook.notebookapp import main
File "/usr/lib/python3.10/site-packages/notebook/notebookapp.py", line
78, in <module>
from .services.kernels.kernelmanager import MappingKernelManager,
AsyncMappingKernelManager
File
"/usr/lib/python3.10/site-packages/notebook/services/kernels/kernelmanager.py",
line 18, in <module>
from jupyter_client.session import Session
File "/usr/lib/python3.10/site-packages/jupyter_client/session.py", line

from jupyter_client.jsonutil import extract_dates, squash_dates,
date_default

10, in <module>
from dateutil.parser import parse as _dateutil_parse
File "/usr/lib/python3.10/site-packages/dateutil/parser/__init__.py",
line 2, in <module>
from ._parser import parse, parser, parserinfo, ParserError

import six
ImportError: bad magic number in 'six': b'\x03\xf3\r\n'
For details, see https://bugzilla.redhat.com/2057340 and
https://github.com/benjaminp/six/issues/359
What would really make things much easier to understand would be if the
exception mentioned what is the path of 'six'.
Consider this example:
A rogue .py file in /usr/bin:
$ sudo touch /usr/bin/copy.py
Programs fail with:
Traceback (most recent call last):
File "/usr/bin/...", line ..., in <module>
...
ImportError: cannot import name 'deepcopy' from 'copy' (/usr/bin/copy.py)
Immediately I can see there is /usr/bin/copy.py which is probably not supposed
to be there.
However, when it is a pyc instead:
$ sudo touch /usr/bin/copy.pyc
Programs fail with:
Traceback (most recent call last):
File "/usr/bin/...", line ..., in <module>
...
ImportError: bad magic number in 'copy': b''
Now I have no idea where "copy" is.
The is a request for that exception to give that infomartion.
