如何舍入数组数组？我已经试过了 numpy.round
How can I round an array of arrays? I tried already numpy.round
[[391.88096195], [386.44174122], [378.13177006], [368.87926224]]
我的输出是上面的数组数组，我想将它四舍五入：
[[391.88], [386.44], [378.13], [368.87]]
您可以使用 list comprehension 语法：
>>> arr = [[391.88096195], [386.44174122], [378.13177006], [368.87926224]]
>>> arr = [[round(xx,2) for xx in aa] for aa in arr]
[[391.88], [386.44], [378.13], [368.87]]
[[391.88096195], [386.44174122], [378.13177006], [368.87926224]]
