In my LightningModule subclass, I used ‘self.hparams = hparams’ which worked fine a week ago but now it unexpectedly returns an Exception saying “AttributeError: can’t set attribute”.

I believe something has been changed recently in the father class **LightningModule** as this issue should be solved by add a “@ATTRI.setter” but here I cannot access the father class.

```auto
class T5FineTuner(pl.LightningModule):
  def __init__ (self, hparams):
    super(T5FineTuner, self). __init__ ()
    self.hparams = hparams

```

Any way to solve this given a recent update on source code, please?

Is this issue already solved [here](https://discuss.pytorch.org/t/pytorch-lightning-module-cant-set-attribute-error/121125/5)?

Yes @ptrblck, it is solved.
