asrulsibaoel :
I have stringified ndarray passed from server to the client-side, the example of that array could be seen below
import numpy as np
str_array = "[[0.1233 0.333 4.1111] [0.1233 0.333 4.1111] [0.1233 0.333 4.1111]]"
arr = np.fromstring(str_array, dtype=np.float32, sep = ' ')
print(arr)
when I run that code, it would raise an error message:
File "example.py", line 89, in <module>
arr = np.fromstring(str_array, dtype=np.float32)
ValueError: string size must be a multiple of element size
I want my stringified array to become a ndarray again. How can I solve this?
Dishin H Goyani :
Use numpy.matrix
and than reshape
>>> np.matrix(str_array).reshape(-1,3)
matrix([[0.1233, 0.333 , 4.1111],
[0.1233, 0.333 , 4.1111],
[0.1233, 0.333 , 4.1111]])
Or to get ndarray
use attribute matrix.A
>>> np.matrix(str_array).reshape(-1,3).A
array([[0.1233, 0.333 , 4.1111],
[0.1233, 0.333 , 4.1111],
[0.1233, 0.333 , 4.1111]])
