preamble
I've been learning Python lately, but I've been having a lot of problems with the Numpy package. The installation was unsuccessful, and using the pip install numpy command also prompted for the wrong version of pip.
After a couple days of hard work, I finally got the numpy package installed in python 3.11.
This sharing is also to take notes for myself in case I change computers and have the same problem.
The installation steps are as follows:
1.Download Numpy file
Download the corresponding version of Numpy files at /project/numpy/#files.
My computer is Windows 11 64-bit, with Python 3.11.0 installed.
cp311: The corresponding version of Python is 3.11.
win_amd64.whl: indicates the file corresponding to Windows 64-bit system.
2. Put the NumPy file into the Scripts folder of your Python installation.
The location is in your Python installation directory, for example, my installation location is D:\Program Files\Python\Python311\Scripts
3. Check the variable environment and add the installation path to the environment variable when installing.
Win11 Path: Settings - System - Advanced System Settings
In the pop-up page, click the "Environment Variables" button in the lower part of the pop-up environment variable management page of the "System Variables" to find the Path, click Edit.
Click New in the page number pop-up, copy the directory of the file and add and save it;
4. Install numpy
Go to your scripts folder, mine is D:\Program Files\Python\Python311\Scripts, and type "cmd" directly into the address bar to bring up the command line. Then type pip install numpy-1.24.2-cp311-cp311-win_amd64.whl and enter. The installation is successfully installed.
5. Checking the installation
Run the python command line
Type import numpy and if no error is reported, the installation was successful.
