Answer 1

尝试此批次获取win7

import numpy as np

def nangmean(arr, axis=None):
    arr = np.asarray(arr)
    valids = np.sum(~np.isnan(arr), axis=axis)
    prod = np.nanprod(arr, axis=axis)
    return np.power(prod, 1. / valids)

Answer 2

java -version:1.8.0_101 -jar jarname.jar

使用上面的方法在这里调用java你可以给你想要使用的java版本，以防你的路径中有多个。

如果Windows有多个JRE版本，如何在命令提示符下获取最新的JRE版本
