I am creating a bundled app with PyInstaller. The app includes numpy so the final size of the bundled app is > 600MB. I want of course to compress the size of the bundled app so I installed upx via brew install upx. However, PyInstaller crashes with the error below.
1- Is there any alternative to UPX or even PyIntaller for macOS?
2- Can I fix this error?
3- Can I run UPX manually after PyInstaller creates the bundled app on selected files? If yes, could you give an example of the command line for UPX?

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?

I've not been able to find anything in the docs about this yet.
I'm running fabric2==2.7.1, invoke==1.6.0, and paramiko==2.8.0 on NixOS stable 22.11.
Invoke currently defaults to /bin/bash, which is a known issue, since operating systems like Alpine and NixOS don't have that path. Fortunately we can specify a command in $PATH rather than manually looking it up, so adding the following to the Connection call does the trick: config=invoke.Config(overrides={"shell": "bash"}).
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.
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:

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

I used to launch the command pserve --reload development.ini in my vagrant box to launch a pyramid server locally. The command was working until the last few days.
However, I now have a syntax error preventing me from launching pserve with or without conf file.

I use python 3.2.3 in this virtualenv
pviews and proutes give the same error
Any help appreciated :)
Regards
==========================
Thanks to Steve Piercy I uninstalled simplejson and pserve now works launched alone! Thanks again.
However, when I launch pserve development.ini, I now have another error:
(py32)vagrant.vm app # pserve --reload development.ini
Starting subprocess with file monitor

I tried to uninstall-reinstall babel with no luck.
Thanks for your help!
Did you recently install simplejson? It was and never will be compatible with Python 3.0 - 3.2. See https://github.com/simplejson/simplejson/issues/66#issuecomment-15360824
