IndexError：指數43770是出界對軸0，大小37550

Question

當我運行：

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

location = [(23913, 43770), (23914, 43731), (23914, 43734), (23916, 43734), 
      (23916, 43740), (23917, 43740), (23917, 43742), (23918, 43743),

      (23914, 43695), (23914, 43698), (23913, 43700), (23913, 43770)] 

im[location] = 4 

我得到以下回溯：

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 

爲什麼不這項工作，爲什麼它是否認爲（23913，43770）中的43770應該沿着軸線0？我試過扭轉元組，並得到相同的錯誤。我錯過了明顯的東西嗎？

Answer 1

而不是(x, y)對（即[(x1, y1), (x2, y2), ...]），您需要通過類似[(x1, x2, ...), (y1, y2, ...)]。這也不是我期待的（見類似問題here）。 @hpaulj's suggestion是使用zip。對於您的問題：

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

給出您正在尋找的結果。
