torch.save({
‘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:
