问题是我试图索引x(一个普通的Python列表)，就好像它是一个numpy数组一样.要解决此问题，只需将x转换为一个numpy数组:

The problem is that I am attempting to index x, an ordinary Python list, as if it were a numpy array. To fix it, simply convert x to a numpy array:

x = list(range(0,10))
random.shuffle(x)
ind = np.argsort(x)
x = np.array(x) # This is the key line
x[ind]

(这已经发生在我身上两次.)

(This has happened to me twice now.)
