ю, что у caffe есть так называемый слой пространственной пирамиды, который позволяет сетям использовать изображения произвольного размера. У меня проблема в том, что сеть, похоже, отказывается использовать изображения произвольного размера в пределах одного пакета. Я что-то пропустил или это настоящая проблема?

Мой train_val.prototxt:
