pycharm plot不显示的问题

问题描述:代码完全没改,之前是可以显示 图片的,然后突然就不能显示了,当然可以本地存储之后再打开查看,但是也太麻烦了… 然后,网上找到的测试代码如下,理论上正常是可以显示的吗,但是我就是显示不出来…

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(-1,1,50)#从(-1,1)均匀取50个点
y = 2 * x

plt.plot(x,y)
plt.show()

在网上找到的解决方法如下,尝试过通通没用,并且有些还自相矛盾…

说法1

在开头加入下述代码:

import matplotlib
matplotlib.use(‘TkAgg’)

结果报错:
ImportError: Cannot load backend ‘TkAgg’ which requires the ‘tk’ interactive framework, as ‘headless’ is currently running

说法2:

将下述代码改成import matplotlib.pyplot as plt:(我本来就是这个,不显示呀555,又改回去了好家伙)

import matplotlib
matplotlib.use(‘TkAgg’)
说法3:

说可能是matplotlib版本问题。

说法4:

File -> Settings -> Tools -> Python Scientific -> 去掉Show plots in tool window勾选。

说法5:

用了科学上网,将全局模式去掉。(但是还是不行555)

搜集的方法都提供如上了,有能解决的就试试吧,最后我选择保存本地再打开看… 保证能画图再说…

fig.savefig('./pic.pdf', format='pdf', dpi=550)  # 输出
