title: How to convert RGB input to grayscale for YOLO v3 Training?
body: <p>I am using the YOLO V3 and my dataset is RGB images however I want to train the network on grayscale version of same dataset. So My question is Is there any method in YOLO v3 that can convert my RGB dataset to grayscale for training automatically or I must first convert my dataset from RGB to grayscale and then feed to the network? OR is it possible to do any pre-processing or conversion using OpenCV or any other library?</p>
