[Python] Why can't I install Numpy on Python 3.14?

I am attempting to install Numpy on Python 3.140a5 to train a NLP deep learning AI. I am using Windows 11. I am attempting to install it through Command Prompt, using pip3.14 install numpy. This gives the following error

Numpy installed correctly on Python 3.13 (that's also why I am using pip3.14 install numpy rather than just pip install numpy, as pip install numpy defaults to trying to install on Python 3.13). I am getting the same error on other, earlier versions of Python 3.14 as well. Specifying a specific Numpy version, like running pip3.14 install numpy==2.2.3 gives the following error instead (this error occurs even trying older Numpy versions):

I attempted to find the "full log" but the file does not appear to actually exist, or if it does it is hidden from me. I also tried running pip3.14 install csv to see what would happen, and got

ERROR: Could not find a version that satisfies the requirement csv (from versions: none)
ERROR: No matching distribution found for csv


When googling, I found suggestions to use pip3.14 -m pip install numpy and python3.14 -m pip install numpy, none of which worked. The first returned

Usage:
pip3.14 <command> [options]

no such option: -m


while the second gave me 'python3.14' is not recognized as an internal or external command, operable program or batch file.

The Python 3.14 documentation for the csv module makes no mention of issues with Python 3.14, and Numpy's documenation says that it is compatible with Python 3.10 or later.

So, what is going on here? Why can't I install Numpy on Python 3.14?
