weights_path	string	absolute path to the weights file (.caffemodel)
cache_path	string	absolute path to the automatically generated tensorcache file
classes_path	string	newline delimited list of class descriptions starting at id 0
data_type	int	TensorRT data type. 32 for kFLOAT, 16 for kHALF, 8 for kINT8
model_image_depth	int	model input image depth / number of channels
model_image_width	int	model input width in pixels
model_image_height	int	model input height in pixels
threshold	float	confidence threshold of classifications, between 0.0 and 1.0
mean1, mean2, mean3	float	ImageNet means
