Import matplotlib into Pycharm to solve the problem that matplotlib fails to run in Pycharm

First, we install matplotlib in the anaconda command window, using the pip command

pip install matplotlib

At this time we write a piece of code in Pythorm

import matplotlib
import matplotlib.pyplot as plt
print(matplotlib.__version__)

ax = plt.subplot(projection='3d')  # 创建一个三维的绘图工程

run will report an error

TypeError: vars() argument must have __dict__ attribute

We first check the version of matplotlib in the python interpreter

You will find that what we just installed with pip is 3.7.0, but the one in pycharm is 3.6.2, so we need to install it again in pycharm

Double-click matplotlib to enter the following interface, click Install Pacekage

Wait for the installation to complete, run the imported matplotlib file in pycharm, and no error will be reported

Test code:

import numpy as np
import matplotlib.pyplot as plt

X = np.linspace(-np.pi, np.pi, 256, endpoint=True)
C,S = np.cos(X), np.sin(X)

plt.plot(X,C)
plt.plot(X,S)

plt.show()
