Inconsistent accuracy when loading weights

[xiaobeiji1]

I found that the accuracy of the prediction when I loaded the model was inconsistent with the accuracy when I trained it. I think there is a problem with the code part

def save_checkpoint(state, is_best, filename='checkpoint.pth.tar'):
"""
Save the training model
"""
if(is_best==1):
torch.save(state, filename)

is_best needs to make a judgment，Otherwise, the last weight will be saved
Further modifications are needed
if epoch > 0 and epoch % args.save_every == 0:
save_checkpoint({
'epoch': epoch + 1,
'state_dict': model.state_dict(),
'best_prec1': best_prec1,
}, 1, filename=os.path.join(args.save_dir, 'checkpoint.th'))

    save_checkpoint({
        'state_dict': model.state_dict(),
        'best_prec1': best_prec1,
    }, is_best, filename=os.path.join(args.save_dir, 'resnet44_best_cifar10.th'))
