Any help would be much appreciated as I don't know how to fix this.
Also, everytime I try opening a Python file, it immediately shuts down after booting up. I assume this has something to do with conflicting versions of Python, but I have uninstalled all versions and reinstalled just 3.9. If there is something I can use to completely rid my computer of all things Python in order to start from the ground up, I would appreciate it very much as I've had more than just this problem when it comes to Python.

First, it looks like a temporary network issue. you can try to rerun the same command, and hopefully it is working. good luck out there.
Second, for different python versions, it is better to use conda to manage it. reference: https://docs.anaconda.com/anaconda/install/index.html

Then I tried installing it using a virtual environment (venv), and the progress bar went a bit further this time, but it still threw pretty much the same error.
Any ideas how to fix this?
Thanks.

Just use --default-timeout=100 parameter with the install. e.g
py -3.7-64 -m pip install --default-timeout=100 tensorflow
I hope, this will help you.

I've tried a lot of methods but useless. Finally I have to reinstalled my python and it works.

What does the error means and how can I install it?
And if I do a google search on how to install tensorflow it tells me to download it from a virtual environment, I don't know how to create virtual environment

As commented by #Dr. Snoopy, error looks like connection issue.
Tensorflow 2.2 or later versions requires Python 3.8.For more please go through official website of Tensorflow.
As suggested by #Raghav Gupta, conda takes care of package versions incompatibility.
conda create --name tf python=3.8 tensorflow #install python 3.8 and latest version of Tensorflow

I am actively trying to get into machine learning, but while i was trying to install tensor flow on my system it kept giving me errors. I am using python 3.7.3 64bit for windows. I have tried different means to install it with no progress. This is the error below,help will be appreciated

As mentioned in this Question.
pip has an default timeout of 15 sec. When trying to install a big file (especially when using slow wifi), this may not be enough.. To fix this just set pip to take longer (for example 1000 sec).
pip install --default-timeout=1000 install tensorflow

Something went wrong when trying to download a certain file (for chunk in download.chunks: gives the hint). In short, you have internet issues. Could be a lot.
