背景：MNIST手写数据识别
问题：pycharm运行程序需要用到MATLAB，明明已经在pycharm的设置中安装matlab，命令行中使用命令pip list也显示有安装matlab，但是运行过程中还是会报错，这是为啥呢？
问题相关代码：
from torchvision.datasets import MNIST
import matplotlib.pyplot as plt
mnist_train = MNIST(root="/MNIST_data",train=True,download=True,transform=None)
print(len(mnist_train))
print(mnist_train[0][0])
plt.imshow(image)
plt.show()
运行结果及报错内容 ：
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "D:\PyCharm 2018.3.7\helpers\pydev\_pydev_bundle\pydev_umd.py", line 197, in runfile

**ModuleNotFoundError: No module named 'matplotlib'**
我的解答思路和尝试过的方法
使用命令行工具切换到安装python的目录下，并使用python -m pip install matplotlib安装matplotlib
遇到超时报错下载不成功，使用命令python -m pip install matplotlib -i https://pypi.douban.com/simple
成功安装matplotlib

但是运行pycharm还是会报错

我想要达到的结果
通过pycharm调用matlab，显示手写数字识别的图像
