Avertissement: Veuillez utiliser des alternatives telles que official / mnist / dataset.py de tensorflow / models
Je fais un simple tutoriel en utilisant Tensorflow, je viens de l’installer, il devrait donc être mis à jour, d’abord je charge les données mnist à l’aide du code suivant:
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)
Mais quand je le lance, je reçois l'avertissement suivant:

J'ai utilisé la ligne os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3' qui devrait éviter d’avoir des avertissements et d’essayer d’autres solutions pour obtenir des mnist, mais toujours afficher les mêmes avertissements, quelqu'un peut-il m'aider à comprendre si cela se produit?
PD: J'utilise Python 3.6 dans Windows 10, au cas où cela aiderait.
Vous pouvez utiliser tf.logging module comme ceci:
import numpy as np
import tensorflow as tf
old_v = tf.logging.get_verbosity()
tf.logging.set_verbosity(tf.logging.ERROR)
from tensorflow.examples.tutorials.mnist import input_data
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)
tf.logging.set_verbosity(old_v)
tensorflow.examples.tutorials est maintenant obsolète et il est recommandé d’utiliser tensorflow.keras.datasets comme suit:
import tensorflow as tf
mnist = tf.keras.datasets.mnist
(X_train, y_train), (X_test, y_test) = mnist.load_data()
