How to use pretrained weights in custom model #24

Hello Team,

I have build a model using retinanet and I would like to use your weights in my model for training. Could you please help me how to use it.
If not in retinanet, how can i use the pretrained model and weights for inference on new images.?

Weights downloaded from: https://dl.fbaipublicfiles.com/detectron/ImageNetPretrained/25093814/X-152-32x8d-IN5k.pkl

I am using CPU system.
