在python 3中使用genfromtxt函数时Numpy抛出错误

My sample code will be like this

我的示例代码将是这样的

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

运行此代码时抛出错误

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

回溯(最近一次调用最后一次):TypeError中的文件“”,第1行:需要类似字节的对象,而不是'str'

1 个解决方案

Encode the string before reading it:

在读取之前对字符串进行编码:

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

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