图像resize_func错误

我下面https://www.kaggle.com/freeman89/dogs-vs-cats-redux-kernels-edition/create-dataset-with-tensorflow 图像resize_func错误

的问题是关于tf.image.resize_image_with_crop_or_pad

resize_func = lambda image: tf.image.resize_image_with_crop_or_pad(image, HEIGHT, WIDTH) 

---------------------------------------------------------------------------

参考：Why do I get ValueError('\'image\' must be fully defined.') when transforming image in Tensorflow?

你知道图像的形状应该是什么吗？你有没有尝试用set_shape设置它？ –

你在使用队列吗？ – Steven

u可以使用tf.map_fn（）来解决这个问题
