This article example describes the installation and use of the Numpy package in Python. Shared for your reference, as follows:
Numpy package installation
preliminary
1. Python installation
2. pip install (e.g., using the pip install command:pip install numpy）
3. Add the folder where pip is located to the path path environment variable.
4. Download the appropriate Numpy installation package in .whl format.download link.
Once the above preparations are ready, proceed with the Numpy installation, first entering the directory where the whl installer is stored. For example, in the C disk:
cd C:\
Then use the command line to install it:
pip install numpyfilename.whl
Notes:Common whl format installers can be downloaded here:/~gohlke/pythonlibs/#numpy
At this point, the installation of Numpy is complete.
Examples of Numpy Usage
import numpy as np print (4,4)
The resulting output is a random 4×4 matrix
