я использую модели тензорного потока , object_detection create_pascal_tf_record.py переименовано create_face_tf_record.py преобразование наборов данных wider_face в TF-запись:
D:\0-STUDY\models\research>python object_detection\dataset_tools\create_face_tf_record.py \
--data_dir=D:/0-STUDY \
--year=widerface \
--output_path=D:\0-STUDY\datasets\widerface\TF_data\train.record \
--set=train
завернутый просто для хорошего взгляда
