[已解决]matplotlib使用时遇到问题

安以陌

1. import matplotlib.pyplot as plt
   
2. squares = [1, 4, 9, 16, 25]
   
3. plt.plot(squares)
   
4. plt.show()

复制代码

代码如上，run moudle时报错，内容如下：
Exception in Tkinter callback

图片也显示了，但是没有曲线，是空白的，哪位鱼油能帮忙看看是什么原因？matplotlib我已经安装成功了的，导入模块什么的也是正常的。

实测安装好matplotlib后，代码没有问题
我怀疑你安装的matplotlib版本和你的python版本不匹配

我电脑是64位操作系统啊，安装的matplotlib也是对应版本的，matplotlib-2.2.0rc1-cp34-none-win_amd64.whl，python版本是34，应该没问题才对，那我再检查检查吧，谢谢了。
