I write a simple jupyter notebook script to block some cells running when need to UI input, such as follows;
when I enter the button, there come out some exceptions like follows;

I don't know how to solve this exception. Do anyone also meet this problem, thanks!

Access denied when trying to run django-admin startproject

I am new to django and I tried to create a project with django-admin startproject command. The tutorial I was referring to had no errors while going through this command but I get the following error. The tutorial and I are not doing it in any virtual environment. Though this error comes, the files and folder are created in the directory I am working in, how should I solve this error?

PyInstaller --onefile is throwing file not found error

I am trying to make an executable of a python 3.10 file using PyInstaller in the command prompt:
python -m PyInstaller --onefile 1.0.py
with "1.0" being my file name. I have done this many times before on the same PC and with the same python version, but for this file it is throwing a "file specified not found" error:

Update:
I have tried uninstalling my python 3.10 and downloading 3.7 instead, as I saw somewhere that PyInstaller is incompatible with 3.8 and above, but this still didn't work for another reason. So I reinstalled 3.10 (effectively at this point I have uninstalled and reinstalled my python and IDE) and I am still getting the same error.

My code:

In the cleverbotfreeapi.py file you have to change:
response = requests.utils.unquote(req.headers["CBOUTPUT"])
To:
getresponse = re.split(r'\\r',str(req.content))[0]
response = getresponse[2:-1]
It seems like the header CBOUTPUT doesn't exist anymore.

PyTorch Getting Started example not working

I followed this tutorial in the Getting Started section on the PyTorch website: "Deep Learning with PyTorch: A 60 Minute Blitz" and I downloaded the code for "Training a Classifier" on the bottom of the page and I ran it, and it's not working for me. I'm using the CPU version of PyTorch if that makes a difference. I'm new to Python and basically learning it for Pytorch. Here's the error message, Control + K isn't working for me because I think the editing interface is different for the first few posts and Stack Overflow needs to fix it. Or it could just be my browser:

BrokenPipeError: [Errno 32] Broken pipe
The error is likely due to multiprocessing in DataLoader and Windows since the tutorial is using num_workers=2. Python3 documentation shares some guidelines on this:
Make sure that the main module can be safely imported by a new Python interpreter without causing unintended side effects (such a starting a new process).
You can either set num_workers=0 or you need to wrap your code within if __name__ == '__main__'
# Safe DataLoader multiprocessing with Windows
if __name__ == '__main__':
# Code to load the data with num_workers > 1
Check this reply on PyTorch forum for more details and this issue on GitHub.

Any idea on how to clean the cache? I already tried to reinstall, to repair, to remove and reinstall again, with no success.
Thanks in advance.
In this case cleaning the temp folder (/home/user/.azure) solved the problem
