python如何保存.npy

z = [[[1, 2, 3], ['w']], [[1, 2, 3], ['w']]]

np.save('test.npy', z)

x = np.load('test.npy')

x:

->array([[list([1, 2, 3]), list(['w'])],

       [list([1, 2, 3]), list(['w'])]], dtype=object)

x

-> {0: 'wpy', 1: 'scg'}

np.save('test.npy',x)

x = np.load('test.npy')

x

->array({0: 'wpy', 1: 'scg'}, dtype=object)

data.item()
