Keras giving OSError: image file is truncated (26 bytes not processed)

Question

I trying to classify images with 3 labels. Training samples are 6000 and validation samples contain 5000 images. The batch size is 10 and number of epochs is 30.

While executing the code in keras, during the training at first epoch, the interpreter gives the following error at 599/600 step.

Below is the snippet of code:

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')

The interpreter gives the following error:

599/600 [============================>.] - ETA: 0s - loss: 0.2541 - acc:   0.9122Traceback (most recent call last):

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