why there are vgg16 in upocr?

[HERIUN]

Thanks for your great work.

I trained model and I found that vgg16 is in upocr. but, in forward process upocr don't use vgg16 at all.

so, when loading my trained model, there are key error(trained model has vgg16, but eval process, vgg16 is disabled..)

def build(args):
    encoder = build_encoder(args)
    decoder = build_decoder(args)
    vgg16 = build_vgg16(args) if not args.eval else None
    ...

so I delete vgg16 my trained model ckpt in class Checkpointer(object) in def load

if self.distributed:
    model = model.module
keys_to_delete = [key for key in checkpoint['model'] if key.startswith('vgg16')]
for key in keys_to_delete:
        del checkpoint['model'][key]
model.load_state_dict(checkpoint['model'])
