处理办法:
删除原有的numpy。一开始按照其他人的教程安装的numpy+mkl

pip uninstall numpy

重新使用pip命令安装新的numpy即可

pip install numpy

也就是不使用numpy+mkl 而是使用numpy

但是在使用sklearn中的KNN函数时会有警告提示:
FutureWarning: Unlike other reduction functions (e.g. skew, kurtosis), the default behavior of mode typically preserves the axis it acts along. In SciPy 1.11.0, this behavior will change: the default value of keepdims will become False, the axis over which the statistic is taken will be eliminated, and the value None will no longer be accepted. Set keepdims to True or False to avoid this warning.
mode, _ = stats.mode(_y[neigh_ind, k], axis=1)
