What is the difference between

a) `torch.from_numpy(a).type(torch.FloatTensor)`  
b) `torch.from_numpy(a).type(torch.float)` ?

When I installed PyTorch via the command `conda install pytorch torchvision -c pytorch`, (b) works. When I installed PyTorch via the command `conda install pytorch=0.1.12 cuda75 -c pytorch` on another PC, (b) does not work but (a) works.

Hi,

`torch.float` has been added recently, it was not in old releases like `0.1.xx`, this is why it does not work.
