python - 来自 tensorflow /模型的警告 : Please use alternatives such as official/mnist/dataset. py

Question

我正在使用 Tensorflow 做一个简单的教程，我刚刚安装了它应该更新它，首先我使用以下代码加载 mnist 数据:

import numpy as np
import os
from tensorflow.examples.tutorials.mnist import input_data
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'

mnist = input_data.read_data_sets("MNIST_data/", one_hot=True)
train_data = mnist.train.images  # Returns np.array
train_labels = np.asarray(mnist.train.labels, dtype=np.int32)
eval_data = mnist.test.images  # Returns np.array
eval_labels = np.asarray(mnist.test.labels, dtype=np.int32)

但是当我运行它时，我收到以下警告:

我使用了 os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3' 这行应该避免收到警告并尝试了其他替代方法来获得 mnist，但是总是出现相同的警告，有人可以帮忙吗我想知道这是怎么回事吗？

PD:我在 Windows 10 中使用 Python 3.6，以防万一。

tensorflow.examples.tutorials 现已弃用，建议使用 tensorflow.keras.datasets 如下:

import tensorflow as tf
mnist = tf.keras.datasets.mnist
(X_train, y_train), (X_test, y_test) = mnist.load_data()
