Please help me, I ran the ssd7_training.ipynb. I have preprocessed to parse the label_train.csv and label_test.csv which have 327 and 141 rows respectively, but the HDF5 dataset generation is 171 and 95. I think I have followed the input format which is 'image_name', 'xmin', 'xmax', 'ymin', 'ymax', 'class_id'. After that when I ran model.fit_generator(), it says the array shape is not correct. I have looked around the DataGenerator and tried different version of Keras and Tensorflow still I could not figured out what is wrong, please help me!
