【问题描述】:
所以说我有一个像这样的 numpy 数组:
[[2 2 2 2 2 2 2 2 2 2 2 2 2 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 2 2 2 2 2 2 2 0]
[2 1 1 1 1 1 1 1 1 1 1 1 1 2 0 0 0 0 0 0 0 0 2 2 2 2 2 2 2 2 2 1 1 1 1 1 1 1 2 0]
[2 1 1 1 1 1 1 1 1 1 1 1 1 2 0 0 0 0 0 0 0 0 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 0]

我想在数组中随机选择一个位置为 1,我该怎么做?
