안녕하세요 강사님. 저번에 친절하게 올려주신 답변을 보고 따라하는 중에 또 질문을 올리네요!! Keras-yolo를 데스크탑 gpu로 train해서 만든 .h5파일을 노트북 cpu로 inference 과정 중 문제가 생겼습니다. 모델 로드는 제대로 되었는데, Yolo의 detect_image()를 사용하여 inference 중 아레와 같은 에러가 발생하였습니다! 혹시 cpu에서 keras-YOLO는 사용이 불가능한 것일까요? -------------- 모델 학습 25회 학습 + validation 2회 진행 중 한번 끊겨서 중간 저장된 model_stage_1.h5로 5회 학습 + 5회 validation 진행한 결과입니다. train_yolo(pretrained_path, annotation_path,classes_path, anchors_path, log_dir,trained_model_name, b_size, epochs_cnt) pretrained_path: C:/JupyterNotebook/ClothClassified/model_data/cloth_stage_1.h5 Create Tiny YOLOv3 model with 6 anchors and 14 classes.
