tensorflow的keras实现搭配dataset,几种形式都工作! tensorflow,keras Sequential模式下: 见代码: fromtensorflowimportkeras as ksimporttensorflow as tf#Generate dummy dataimportnumpy as np x_train= np.random.random((1000, 20)) y_train= ks.utils.to_categorical(np.random.randint(10, size=(1000, 1)),...
使用tf.keras.utils.get_file函数下载训练数据集文件。该函数会返回下载文件的文件路径。 train_dataset_url="https://storage.googleapis.com/download.tensorflow.org/data/iris_training.csv"train_dataset_fp=tf.keras.utils.get_file(fname=os.path.basename(train_dataset_url),origin=train_dataset_url)print(...
