Description
Hi - torch cdist cuda is not implemented for fp16. How could I fix?
return th.cdist(x, y, p=2)
File "/home/ubuntu/anaconda3/envs/torch/lib/python3.7/site-packages/torch/functional.py", line 1119, in cdist
return _VF.cdist(x1, x2, p, None) # type: ignore
RuntimeError: "cdist_cuda" not implemented for 'Half'
