Learning python process want to use python matlabplot drawing function, encountered a large number of problems, and then all the way through, and finally installed successfully, it is not easy to post to remember.
1 First open cmd
win+r
2 pip installation
pip3 install --user numpy scipy matplotlib
The -user option allows you to set it to be installed only under the current user, instead of writing to the system directory. The default is to use a foreign line, which is too slow, so we'll just use the Tsinghua image::.
pip3 install numpy scipy matplotlib -i /simple
How the network is not good, we can install them individually one by one
pip3 install numpy s -i /simple pip3 install scipy -i /simple pip3 install matplotlib -i /simple
3 Error encountered while installing matlabplot:
Using legacy ' install' for matplotlib, since package 'wheel' is not installed.
Installing collected packages: matplotlib
Running install for matplotlib ... error
ERROR: Command errored out with exit status 1:
Check your own python version:
Python 3.9.0 (tags/v3.9.0:9cf6752, Oct 5 2020, 15:34:40) [MSC v.1927 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license()" for more information.
My python is 3.9 AMD64
Find worldcould at the /~gohlke/pythonlibs/ site
Pick your own corresponding .whl download. My pick:
wordcloud-1.8.0-cp39-cp39-win_amd64.whl
Then go back to cmd
4 Installation
pip install wordcloud-1.8.0-cp39-cp39-win_amd64.whl
5 Error again
Using legacy ' install' for matplotlib, since package 'wheel' is not installed.
Direct installation of wheel
pip install wheel
6 Installing matlabplot again
pip3 install matplotlib -i /simple
unsuccessful
7 Find matlabplot in /~gohlke/pythonlibs/
Download and install.
pip3 install matplotlib-3.3.2-cp39-cp39-win_amd64.whl
It shows a successful installation, so hurry up and find a program to try:
import numpy as np
from matplotlib import pyplot as plt
x = (1,11)
y = 2 * x + 5
("Matplotlib demo")
("x axis caption")
("y axis caption")
(x,y)
()
Successful installation with a twist
