In this tutorial, we've learned how to find or compute the mean, the median, and the mode using Python. We first covered, step-by-step, how to create our own functions to compute them, and then how to use Python'sstatisticsmodule as a quick way to find these measures....

报错1:AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?pkgutil的ImpImporter在Python3.13已经弃用了,但是旧版Numpy依然会尝试使用,所以导致了这个错误。参考Issue而PaddleClas的requirements很久没有更新过,所以会在安装依赖的过程中遇到此问题,使用较新版本的Numpy即可。
