一个简单的方法是读取文件，在分隔符处拆分获得的字符串，清除剩余的不必要的行，并在这些字符串列表上使用numpy.loadtext。（正如documentation中所解释的，在numpy.loadtext中作为参数的字符串列表被视为行）

import numpy as np
from typing import List

filename: str = "data_file.txt" # Put your filename here instead

with open(filename, "r", encoding="utf-8") as file:
    content: str = file.read()

datas: List[str] = content.split(4 * "#######\n")
arrays: List[np.ndarray] = []
for data in datas:
    data_list: List[str] = data.replace("#######\n", "").split("\n")
    arrays.append(np.loadtxt(data_list))
