NumpyArrayIterator` should have rank 4 怎么解决

history = model.fit_generator(
    aug.flow(x_train, y_train, batch_size=BS),
    validation_data=(x_test, y_test),
    steps_per_epoch=len(x_train) // BS,
    epochs=EPOCHS, verbose=1
    )

VaueError: ('Input data in `NumpyArrayIterator` should have rank 4. You passed an array with shape', (2361, 0))

你这个是矩阵大小不匹配的问题，你的排查上下文。
