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]) Traceback (most recent call last): File "E:\joshua\python\demo\main.py", line 40, in plt.imshow(img[0]) File "C:\Python310\lib\site-packages\matplotlib\pyplot.py", line 2668, in imshow __ret = gca().imshow( File "C:\Python310\lib\site-packages\matplotlib\pyplot.py", line 2282, in gca return gcf().gca() File "C:\Python310\lib\site-packages\matplotlib\pyplot.py", line 879, in gcf return figure() File "C:\Python310\lib\site-packages\matplotlib\_api\deprecation.py", line 454, in wrapper return func(*args, **kwargs) File "C:\Python310\lib\site-packages\matplotlib\pyplot.py", line 813, in figure manager = new_figure_manager( File "C:\Python310\lib\site-packages\matplotlib\pyplot.py", line 382, in new_figure_manager _warn_if_gui_out_of_main_thread() File "C:\Python310\lib\site-packages\matplotlib\pyplot.py", line 360, in _warn_if_gui_out_of_main_thread if _get_required_interactive_framework(_get_backend_mod()): File "C:\Python310\lib\site-packages\matplotlib\pyplot.py", line 208, in _get_backend_mod switch_backend(rcParams._get("backend")) File "C:\Python310\lib\site-packages\matplotlib\pyplot.py", line 331, in switch_backend manager_pyplot_show = vars(manager_class).get("pyplot_show") TypeError: vars() argument must have __dict__ attribute 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）

from matplotlib import pyplot as plt plt.imshow(img[0]) plt.show()
