Giving memory error while running unsupervised clustering on Custom Data

[AnshulVijay]

RuntimeError: unsupported operation: more than one element of the written-to tensor refers to a single memory location. Please clone() the tensor before performing the operation.

Can you tell me, what's causing this issue

[WeiWenQiang123456]

p_i = p_i_j.sum(dim=1).view(k, 1).expand(k, k).clone()
p_j = p_i_j.sum(dim=0).view(1, k).expand(k,k).clone()

try this?
