load a pretrained model pytorch - dict object has no attribute eval
def save_checkpoint(state, is_best, filename='checkpoint.pth.tar'):
    torch.save(state, filename)
    if is_best:
        shutil.copyfile(filename, 'model_best.pth.tar')


save_checkpoint({
                'epoch': epoch + 1,
                'arch': args.arch,
                'state_dict': model.state_dict(),
                'best_prec1': best_prec1,
                'optimizer': optimizer.state_dict()
            }, is_best)


I am saving my model like this. How can I load back the model so that I can use it in other places, like cnn visualization? 

This is how I am loading the model now: 

torch.load('model_best.pth.tar')


But when I do this, I get this error:


  AttributeError: 'dict' object has no attribute 'eval'


What am I missing here???

EDIT: I want to use the model that I trained to visualize the filters and grads. I am using this repo to make the vis. I replaced line 179 with torch.load('model_best.pth.tar')

First, you have stated your model.
And torch.load() gives you a dictionary. That dictionary has not an eval function. So you should upload the weights to your model.

import torch
from modelfolder import yourmodel

model = yourmodel()
checkpoint = torch.load('model_best.pth.tar')
try:
    checkpoint.eval()
except AttributeError as error:
    print error
### 'dict' object has no attribute 'eval'

model.load_state_dict(checkpoint['state_dict'])
### now you can evaluate it
model.eval()
