I'm trying to run flake8 on a docker django built like described here (tutorial page)
when building the docker image I get an error from flake8 which is run in an docker-compose file with like so
$ flake8 --ignore=E501,F401 .

When I run flake8 with the --verbose flag, I get an error like this:

Does anyone know how to solve this?
Additional Data:

Thanks for helping!
If you don't care for flake8, then just delete that line. It will work. I had the same problem.
I know this isn't an answer. I would add a comment instead if I could.
I encountered a very similar error profile when I had refactored and left a lot of data which formerly had been in the top of the project down in what became the package folder. There were 33621 files including .venv, .nox, .pytest_cache, .coverage.
File "/usr/lib/python3.8/multiprocessing/pool.py", line 448, in <genexpr>

IndexError: string index out of range
If you see a similar signature (the parallel processing engine being overwhelmed in some way and throwing an exception), you may want to review your project directory structure and make sure that you did not put this kind of data in your sources directories.

I was forced into some software updates on my laptop (ThinkPad) and after the update when I tried to open Spyder (via Anaconda) and it won't open. I don't have any experience in errors like this or fixing this stuff (and I am aware this may be something that is super simple). Please help. This is the application launch error I am getting:

Did you try to run spyder on the terminal?
It should be prebuild in Anaconda.
Your Spyder config file should contain but is missing 'custom-1/background' in section: 'appearance'. If you have no experience, the easiest thing for you to do is uninstall and install Spyder (via Anaconda). Your other option is to find the config file called in line 513 of C:\Users\cyrra\anaconda3\lib\site-packages\spyder\config\user.py". Then open the config file (if it exists) and correct it. If the file is not found, search for that config file and place it in the expected location.
I downloaded the ansible-2.0.0-0.2.alpha2.tar.gz and installed it on my control machine. However now I'm not able to ping any of my machines. Previously using v1.9.2 i could communicate with them. Now it gives the following error:
Unexpected Exception: lstat() argument 1 must be encoded string without NULL bytes, not str
the full traceback was:

Any help would be appreciated.
This is a known bug due to some Unicode changes made to the playbook parser in 2.0. Several versions of Python shipped with a version of shlex.split() that fails horribly on Unicode input- you likely have one of them installed. The bug has been worked around and will be included in the next drop. See https://github.com/ansible/ansible/issues/12257

Anyone else seen this? I've seen it mentioned in this pull request (https://github.com/nose-devs/nose/pull/710) but not clear what the solution was.
I just went into the nose source code and commented out lines 156-158.
#self.coverInstance.exclude('#pragma[: ]+[nN][oO] [cC][oO][vV][eE][rR]')
#self.coverInstance.load()
#self.coverInstance.start()
All my tests run fine now. O_o
I am relatively new to Python, and at the same time, am attempting to install mod_dav_svn into my Apache web server. I am looking to get some idea of the scope of the error I'm receiving.
At the command line, I type in 'sudo yum install mod_dav_svn' and receive this output:

The only other question I could find with a similar error was this one: https://stackoverflow.com/search?q=can%27t+start+new+thread+python, but I'm not sure it has to do with running too many threads since I am the only one using the server, and this is one of the first python commands I have used. Could someone point me in the right direction, or towards some material that may help me troubleshoot the issue? Thanks!
Disable yum-fastermirror and you should be able to complete the install.
yum --disableplugin=fastestmirror update
Are you on a virtual machine?
I'm creating a code that gets image's urls from any web pages, the code are in python and use BeutifulSoup and httplib2.
When I run the code, I get the next error:

Are you using latest version of BeautifulSoup?
This seems a known issue of version 3.1.x, because it started using a new parser (HTMLParser, instead of SGMLParser) that is much worse at processing malformed HTML. You can find more information about this on BeautifulSoup website.
As a quick solution, you can simply use an older version (3.0.7a).
To catch that error specifically, change your code to look like this:
try:
iSoupList = BeautifulSoup(response, parseOnlyThese=SoupStrainer('img'))
except HTMLParseError:
#Do something intelligent here
Here's some more reading on Python's try except blocks:
http://docs.python.org/tutorial/errors.html
I got that error when I had the string =& in my HTML document. When I replaced that string (in my case with =and) then I no longer received that parsing error.
