Numpy throws error while using genfromtxt function in python 3

Question

My sample code will be like this

import numpy as np
from io import BytesIO

data = "1, 2, 3\n4, 5, 6"
np.genfromtxt(data, delimiter=",")

while run this code throws error

Traceback (most recent call last): File "", line 1, in TypeError: a bytes-like object is required, not 'str'

I think you want np.genfromtxt(BytesIO(data), delimiter=",") the error suggests it doesn't like the string as is — Andrew Arias, Dec 31 '17 at 03:24

Encode the string before reading it:

data = "1, 2, 3\n4, 5, 6"
np.genfromtxt(BytesIO(data.encode()), delimiter=",")

array([[ 1.,  2.,  3.],
       [ 4.,  5.,  6.]])
