I am trying to download a course on edx. Please refer to the following readme (https://github.com/coursera-dl/edx-dl/blob/master/README.md). I installed Anaconda for Windows (I am running Windows 10 in Parallel Desktop).
In the last step, I typed in the following command: C:\edx-dl-master\edx-dl-master>edx-dl -u user#user.com COURSE-URL and upon entering my edX password, get the following:
Building initial headers for future requests.
Getting initial CSRF token.
Found CSRF token.

I just start learning manim and Im not so good at python.
when I was running manim examples given by the manim kindergarten, there was a error about index but I really don't know how to solve it.
As follows
manimgl example_scenes.py OpeningManimExample
Here is the information

It seems that the problem is about vectorized_mobject.py.
I've search all google but it seems no one has the same problem like mine.
In the docs of manim kindergarten I found no solution.
Hopefully some here once had the same problem and please let me know how to solve it.
Really thanks if someone could help me.
If you want to use Manim. I'd suggest you install ManimCE version from Manim Community. As it is more stable.
If you want to use, Manimgl to reproduce the animations from 3b1b videos.
Make sure you have FFmpeg and latex properly installed (Using
Miktex? make sure you enable it to install tex packages on it's own
or install all the latex packages).
Create a python virtual environment. Enable the venv you have just created.
Install manim using pip with pip install manimgl. Don't install it from
the source, as there are still some bugs at the time of writing.
If you followed all the steps correctly then running manimgl example_scenes.py OpeningManimExample should work.
As you can see, I use the right command and it keeps telling me the usage instead of creating the right file for me.
enter image description here
(WebScraping) G:\>pipreqs G:\PY CODE\WebScraping
Usage:
pipreqs [options] [<path>]
And if I just randomly input the path file, it will tell me, file doesn`t exist.

This keeps bothering me
I wonder is there someth
Try adding quotes:

if you know how to overcome this error, please answer. Thank you.
I think what your problem is, that you're missing stdout. I've had a similar problem with a script that was invoked from KDE. It kind of failed with a similar error message.
My fix for the moment was to simply redirect the stdout to /dev/null. I assume that this won't quite work, considering you are working from within a shell that should have stdin/stout. You might have to reconsider your working environment. But just a guess.
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:
Fatal Python error: deletion of interned string failed

Does anyone know how to solve this?
Additional Data:
running docker-compose v1.25.4 on an raspberry 3 with buster lite.
Installed and compiled Python 3.8.2 from source with the flag --enableloadable-sqlite
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.

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 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:

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
