Я хочу обнаруживать объекты на изображениях, следуя этому руководству (https://medium.com/deepquestai/train-object-detection-ai-with-6-lines-of-code-6d087063f6ff). Однако я получаю сообщение об ошибке, которое не могу устранить. Что я могу с этим поделать, учитывая, что я не могу изменить исходный код с imageai
и, следовательно, не исправить ошибку таким образом (https://github.com/google/tangent/issues/95)?
Это мой импорт:
!pip3 install tensorflow-gpu==1.13.1
!pip install imageai --upgrade
from imageai.Detection.Custom import DetectionModelTrainer
Я запускаю этот код:
data_path = 'leaf-images-with-pascal-voc-annotations/'
trainer = DetectionModelTrainer()
trainer.setModelTypeAsYOLOv3()
trainer.setDataDirectory(data_directory=data_path)
trainer.setTrainConfig(object_names_array=['leaf'], batch_size=16, num_experiments=100,
train_from_pretrained_model="pretrained-yolov3.h5")
trainer.trainModel()
Я пытался использовать разные версии tenenflow, но получаю это сообщение об ошибке:
