findfont: Generic family sans-serif not found because none of the following families were found: SimHei

回答: 这个问题是由于找不到字体家族'sans-serif'导致的。根据引用\[1\]和引用\[2\]的报错信息，可以看出在系统中找不到SimHei字体。为了解决这个问题，你可以按照引用\[3\]中的步骤进行操作。首先，在Python环境中输入以下代码来查看字体路径：import matplotlib matplotlib.matplotlib_fname()。这将显示matplotlib的配置文件路径。然后，你可以将SimHei字体文件复制到该路径下的字体文件夹中。这样，当你再次运行程序时，就能够找到并使用SimHei字体了。
