Error: The `preds` should be probabilities, but values were detected outside of [0,1] range. about pytorch_cifar10

I am just facing this issue. I got around by downgrading and using the same version used of pytorch-lightning==1.1.0.

However, that caused also a problem of compatibility with torchtext. And I also tried to solve that by downgrading that as well torchtext==0.8.1. However, no resolution after that.

I am running the following

!python train.py --gpu_id=0 --data_dir='datasets' --classifier vgg11_bn

And getting

Traceback (most recent call last):

I modified the code in the CIFAR10Module like:

def forward(self, batch):
        images, labels = batch
        outputs = self.model(images)
        _, predictions = torch.max(outputs, 1)
        loss = self.criterion(outputs, labels)
        accuracy = self.accuracy(predictions, labels)
        return loss, accuracy * 100

and it seems to have solved the problem.
