Generally, numpy is installed in “control panel + CMD”
Enter “PIP install numpy” in the command line window
The numpy installed at this time is not in the directory line of Python
No module named numpy will report an error, even if “import numpy as numpy” is imported at the beginning of the python program
2. Solutions:
(1) It is to directly find the python installation location in the DOS window and directly enter the “PIP install numpy” statement
Enter enter and wait for installation
(2) Is it mandatory to download the latest version after installation
Find the installation location of Python in DOS window, and input “PIP install numpy — ignore installed numpy” statement
Will be forced to reload in a new location, this is to install the numpy package into python
Note that the following statement is entered in the win system
If you want to build a Linux system, you should add more “sudo” fields in front of it
Namely: “sudo PIP install numpy — ignore installed numpy”
This chapter is my opinion, let’s make progress together
