cơ học cơ bản

Để tạo đường dẫn đầu vào, bạn phải bắt đầu với nguồn dữ liệu. Ví dụ: để tạo một

import pathlib
import os
import matplotlib.pyplot as plt
import pandas as pd
import numpy as np

np.set_printoptions[precision=4]

import pathlib
import os

Điểm kiểm tra trình lặp

Tensorflow hỗ trợ lấy các điểm kiểm tra để khi quá trình đào tạo của bạn bắt đầu lại, nó có thể khôi phục điểm kiểm tra mới nhất để khôi phục hầu hết tiến trình của nó. Ngoài việc kiểm tra các biến mô hình, bạn cũng có thể kiểm tra tiến trình của bộ lặp tập dữ liệu. Điều này có thể hữu ích nếu bạn có tập dữ liệu lớn và không muốn bắt đầu tập dữ liệu từ đầu mỗi lần khởi động lại. Tuy nhiên, xin lưu ý rằng các điểm kiểm tra của trình vòng lặp có thể lớn, do các phép biến đổi như
