Noise and Data could not be broadcast together

I am getting the following error:

```
  File "/home/faraz/PycharmProjects/noise2void/pytorch-noise2void/dataset.py", line 80, in __getitem__
    label = data + self.noise[index]
ValueError: operands could not be broadcast together with shapes (840,859,4) (321,481,3) 
```
Is this the channel issue?

Thanks
