在使用飞浆平台，练习平台上的demo：实践：手写数字识别任务，出现了下面的错误，demo地址： https://www.paddlepaddle.org.cn/documentation/docs/zh/guides/beginner/quick_start_cn.html
报错如下：
E:\joshua\python\demo\main.py:40: MatplotlibDeprecationWarning: Support for FigureCanvases without a required_interactive_framework attribute was deprecated in Matplotlib 3.6 and will be removed two minor releases later.
plt.imshow(img[0])

问题解决方式：
1.对pycharm编辑器进行设置
通过下面路径 File | Settings | Tools | Python Scientific
2.然后取消勾选show plots in tool window后，点击apply按钮，再点击ok按钮。
3.代码结尾加上 plt.show()后，代码就可以正常执行且不报错（注：这里的plt是我引用的别名，import matplotlib.pyplot as plt）
from matplotlib import pyplot as plt
plt.imshow(img[0])
plt.show()
