Question

当我跑步时：

im = np.zeros((37550, 59759))  

location = [(23913, 43770), (23914, 43731), (23914, 43734), (23916, 43734),

im[location] = 4

我得到以下追溯：

IndexError                                Traceback (most recent call last)
<ipython-input-6-2fb0def4341d> in <module>()
----> 1 arr[location] = 4

IndexError: index 43770 is out of bounds for axis 0 with size 37550

为什么这不起作用，为什么它认为（23913,43770）中的43770应该沿0轴？我试过反转元组，我得到了同样的错误。我错过了一些明显的东西吗？

Answer 1

而不是(x, y)对（即[(x1, y1), (x2, y2), ...]），您需要传递[(x1, x2, ...), (y1, y2, ...)]之类的内容。这也不是我所期待的（见同样的问题here）。 @hpaulj's suggestion是使用zip。对于你的问题：

im[tuple(zip(*location))] = 4

给出您正在寻找的结果。

IndexError：索引43770超出了轴0的大小为37550的范围
