TL;DR: Невозможно выяснить, как использовать переобученное inceptionV3 для нескольких прогнозов изображения.
Привет, добрые люди:) Я потратил несколько дней на поиск многих записей stackoverflow и документации, но я не смог найти ответ на этот вопрос. Был бы очень признателен за любую помощь в этом!
Я переучивал модель на основе тензорного потока V3 на новых снимках, и она может работать над новыми изображениями, следуя инструкциям в https://www.tensorflow.org/versions/r0.9/how_tos/image_retraining/index.html и используя следующие команды:
bazel build tensorflow/examples/label_image:label_image && \
bazel-bin/tensorflow/examples/label_image/label_image \
--graph=/tmp/output_graph.pb --labels=/tmp/output_labels.txt \
--output_layer=final_result \
--image= IMAGE_DIRECTORY_TO_CLASSIFY
Однако мне нужно классифицировать несколько изображений (например, набор данных), и я серьезно зациклился на том, как это сделать. Я нашел следующий пример в
https://github.com/eldor4do/Tensorflow-Examples/blob/master/retraining-example.py
о том, как использовать переобученную модель, но опять же, очень мало деталей о том, как изменить ее для нескольких классификаций.
Из того, что я собрал в учебнике MNIST, мне нужно ввести feed_dict в объект sess.run(), но он застрял там, поскольку я не мог понять, как его реализовать в этом контексте.
Любая помощь будет чрезвычайно оценена!:)
