Question

我尝试使用3个标签对图像进行分类。训练样本为6000，验证样本包含5000个图像。批量大小为10，时期数为30。

在keras中执行代码时，在第一个纪元的训练期间，解释器在599/600步时给出以下错误。

以下是代码片段：

model.fit_generator(
train_generator,
steps_per_epoch=nb_train_samples // batch_size,
epochs=epochs,
validation_data=validation_generator,
validation_steps=nb_validation_samples // batch_size)

model.save_weights('weights_img.h5')
model.save('model_img.h5')

解释器出现以下错误：

The above exception was the direct cause of the following exception:

Keras给出OSError：图像文件被截断（未处理26个字节）
