Unable to pip install PyTorch due to [Errno 28] No space left on device

Trying to install PyTorch using this command:
py -m pip install --cache-dir=D:/CodePackages/temp --target=D:\CodePackages torch==1.13.1 -f https://download.pytorch.org/whl/torch_stable.html
And it is giving me these errors:

I'm using Python 3.10.8, latest version of pip, Windows 10.
The directory has more than enough space and I've tried changing the cache directory with --cache-dir without success. Any help is appreciated :) thanks

The error message you are seeing is likely due to one of the following reasons:
The specified path D:/CodePackages/temp or D:\CodePackages does not exist or is not accessible. You should make sure that the path exists and you have the necessary permissions to write to it.
The pip version that you are using is outdated. You should try running py -m pip install --upgrade pip to update pip to the latest version.
There may be an issue with the URL you are using in the -f flag. Try using the URL https://download.pytorch.org/whl/cu111/torch-1.13.1%2Bcu111-cp37-cp37m-win_amd64.whl .
If you have other version of python or pytorch installed it might cause conflict, you should try to uninstall previous versions of PyTorch, python and install the correct version.
Sometimes firewall or antivirus software can block the installation process, you should try to add exception in your firewall or antivirus software.
You might also want to try installing PyTorch without the --target and --cache-dir flags, to see if that resolves the issue.
py -m pip install torch==1.13.1 -f https://download.pytorch.org/whl/cu111/torch-1.13.1%2Bcu111-cp37-cp37m-win_amd64.whl

Installation of py3exiv2 (using pip) on my MacBook Pro M1 fails, with the InstallationError: No .egg-info directory found in... error.
I have tried the solutions posted in other place such as this thread, to no avail:

Try this.
pip install --upgrade setuptools pip

Ok, I figured out why this does not work on M1 MacOS and how to fix it.
The problem is that M1 MacOS puts homebrew in /opt/ instead of /usr/local/. The py3exiv2 people hard coded /usr/ in setup.py. I will try to reach out to them, but am not so experienced. If you do know how to report it, please do.
Here is the full HowTo:
Install needed dependecies. At least this should be:
brew install exiv2 boost boost-python3
Download py3exiv2 from here:
https://pypi.org/project/py3exiv2/#files
Extract the tar.gz into a folder. You can just doubleclick it in Finder.
Edit the setup.py and change line 25. Make sure the version number matches yours. Check the path with ls.
Old:
def get_libboost_osx():
places = ["/usr/local/lib/"]
New:
def get_libboost_osx():
places = ["/opt/homebrew/Cellar/boost-python3/1.78.0/lib/"]
Compress the folder content again. Your version number or foldername might be different.
tar -czvf py3exiv2-0.9.3-edited.tar.gz py3exiv2-0.9.3/*
Then add the variables as was answered before. Note that for M1 Macs the paths are also in /opt/homebrew/ and not /usr/local/. Also make sure the version numbers match yours. I checked everything by browsing the folders with ls.
export CPLUS_INCLUDE_PATH=/opt/homebrew/Cellar/exiv2/0.27.5_1/include/:/opt/homebrew/opt/libssh/include/:/opt/homebrew/Cellar/boost/1.78.0_1/include/
export LDFLAGS="-L/opt/homebrew/Cellar/boost-python3/1.78.0/lib -L/opt/homebrew/Cellar/exiv2/0.27.5_1/lib"
Then install it. The -v gives you more hints. That is how I found the places thing in the first place. It just never found boost and it will only tell you in verbose mode.
pip3 install py3exiv2-0.9.3-edited.tar.gz -v
Hope this helped :)

Cannot install python package in Git Bash

I'm trying to install a package from my company's internal artifactory storage. I'm getting 2 exceptions in Gitbash that I can't understand. When I run Pip Freeze I don't see the install package, so I don't believe it is already installed.
After reading the exceptions, I don't understand what's going on, is anyone familiar with this?

It looks like you have the wrong version of the tables package installed. Trying installing the required version with pip install tables==3.2.0.

Failure trying to install Python 2.x pip & setuptools on MS Windows 7.0

I have just installed Python 2.6.6 64-bit. I first had problems on Python command line because of an encoding bug which I think I solved it based on instructions mentioned in: Windows command line encoding causes Python crash.
Then I tried to install pip using admin's Windows powershell after reading instructions provided in: How to install Python pip and PyPA pip installation manual. It failed and I received this in shell:
