Load model from checkpoint.pth.tar

‘epoch’: epoch,
‘model’: net,
‘model_state_dict’: net.state_dict(),
‘best_mean_iu’: meanIU_best,
}, os.path.join(model_path, ‘checkpoint.pth.tar’))
i save model like this.

checkpoint = torch.load(‘checkpoint.pth.tar’)
net = torch.load(checkpoint[‘model’])

but i try to load model from checkpoint, it would appear error like this:

Traceback (most recent call last):
File “/home/liuyf/DenseNet_clockwork/CamVid_DenseNet/camvid_train.py”, line 35, in

AttributeError: ‘DataParallel’ object has no attribute ‘tell’


Can anyone provide some help for me?

Corrected line:

net = checkpoint['model']
