Hello,

The following code replace a number (with probability `corrupt_prob`

) of true labels in the training (or test) data with random labels:

```
labels = np.array(self.train_labels if self.train else self.test_labels)
np.random.seed(12345)
mask = np.random.rand(len(labels)) <= corrupt_prob
rnd_labels = np.random.choice(self.n_classes, mask.sum())
labels[mask] = rnd_labels
```

In PyTorch 0.2 it gave me the following error:

TypeError: len() of unsized object

The type of `labels`

is `[torch.LongTensor of size 60000]`

.

Could anybody help me to fix this please?

Thank you in advance for your help!
