        0.        , 0.        , 0.0088979 ]])

我想得到

array([0.00938241, 0.00902791        , 0.00744846        , 0.00607864        , 0.00508451        ,
        0.00731141        ,...])

作为我的输出，即我只想将它们全部汇总成一个数组。我该如何使用两个以上的阵列？我没有找到解决此问题的任何文档...

Answer 1

只需沿轴1求和

还使用np.array代替未定义的pd.Dataarray

arr.sum(axis=1)

如何在numpy中添加多个矩阵？
