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：

Process finished with exit code 1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）
代码语言：javascript复制from matplotlib import pyplot as plt
plt.imshow(img[0])
plt.show()本文为joshua317原创文章,转载请注明：转载自joshua317博客 https://www.joshua317.com/article/298
