针对你遇到的 vgg19.preprocess_input(img) 报错output array is read-only 的问题,我们可以从以下几个方面进行排查和解决: 检查img数组是否被设置为只读: 在Python中,NumPy数组可以被设置为只读。如果img是一个只读数组,那么vgg19.preprocess_input在尝试修改它时就会报错。你可以通过检查img.flags.writeable来确认...

This tutorial shows how to load and preprocess an image dataset in three ways. First, you will use high-level Keras preprocessing utilities and lay...

1、导包 from keras.applications.resnet50 import preprocess_input 2、作用 使图像符合模型所需的格式 img = preprocess_input(img)
batch_size=32img_height=180img_width=180 It's good practice to use a validation split when developing your model. You will use 80% of the images for training and 20% for validation. 代码语言:javascript 复制 train_ds=tf.keras.preprocessing.image_dataset_from_directory(data_dir,validation_spli...
