problems when load pretrained model.

Open git0405 opened this issue 2 years ago • 0 comments

thanks for your help. When i try to reload the pretrained model, the problem is

"Failed to to load model "self.pretrained_model "from save path: %s" % self.pretrained_model) i changed the 'pretrained_model' path in densenet_params{} but it still does not work.
