I want to make '1 2 3' into a numpy [1, 2, 3]

I've tried

x = '1 2 3'
x = np.fromstring(x, dtype=int, sep=' ')

and it works, but is there any other way to do it? Maybe using np.array()? Thanks.

CodePudding user response：

If you really want you could do np.array(x.split()), but the numpy.fromstring method will be faster.

Timing for np.fromstring on 1000 times x: 45.2 µs ± 4.29 µs

Timing for np.array: 329 µs ± 67.6 µs
