Module 'torch' has no attribute 'FloatTensor'

Hi guys,
I installed PyTorch in Ubuntu16.04 with conda, Python 3.6, without CUDA. I can import torch successfully, but when I write “dtype = torch.FloatTensor”, it displays " module ‘torch’ has no attribute ‘FloatTensor’ ".

Could anyone please tell me why or what can I do to use torch.FloatTensor?
Thanks !
Best,
