如何在 pyhton numpy 数组中输入空格分隔的整数。 （就像 list(map(int,input().spli(" ")) 函数对列表所做的那样。）

Question

I have tried to find alternatives but only available for list not for numpy arrays

I tried this but didnt work:

5
1 2 3 4 5
Traceback (most recent call last):
  File "<string>", line 6, in <module>
  File "/usr/local/lib/python3.8/dist-packages/numpy/core/numeric.py", line 204, in ones
a = empty(shape, dtype, order)
TypeError: expected sequence object with len >= 0 or a single integer

I need a version of list(map(int,input().split(" ")) for numpy arrays.

You can just convert to a numpy array:

import numpy as np

numbers = input('Enter some numbers: ').split()
x = np.array(list(map(int, numbers)))
print(x)

Output:

Enter some numbers: 1 2 3 4 5
[1 2 3 4 5]
