In [the tutorial](https://pytorch.org/tutorials/beginner/blitz/neural_networks_tutorial.html), `torch.arange` is being used as a FloatTensor. This behavior was changed in pytorch/pytorch#7016 to return a LongTensor. I removed the `torch.arange` usage and instead construct a tensor with `torch.randn`
