示例如下: from tensorflow.keras import datasets (x,y),(tx,ty) = datasets.imdb.load_data() print("全部数据:",len(x),' 第一个评论:',len(x[0])) (x100,y100),(tx100,ty100) = datasets.imdb.load_data(maxlen=100) print("长度小于100:",len(x100),' 第一个评论【100】:',len(x100[...
对于CIFAR10数据集,可以使用TensorFlow的tf.keras.datasets.cifar10.load_data()函数来加载数据。这个函数同样会自动下载并返回训练集和测试集的图像数据和标签。具体代码如下: 代码语言:txt 复制 import tensorflow as tf # 加载CIFAR10数据集 (train_images, train_labels), (test_images, test_labels) = tf...
Ingesting a large dataset and preprocessing it efficiently can be tricky to implement with other Deep Learning libraries, but TensorFlow makes it easy thanks to the Data API: you just create a dataset object, tell it where to get the data, then transform it in any way you want, and TensorF...
