Graph compile failed when torch.repeat

Inference

Hi, I’ve met the following graph compiling error when doing a torch.repeat, could you give me some hints on why it happens?

import torch
import habana_frameworks.torch.core as htcore
import habana_frameworks.torch.gpu_migration

t=torch.zeros([2,4,16,64,64])

# Correct!!
t.to('cpu').unsqueeze(1).unsqueeze(1).repeat(1, 2, 1, 1, 1, 1, 1)

# Graph compile failed!!
t.to('hpu').unsqueeze(1).unsqueeze(1).repeat(1, 2, 1, 1, 1, 1, 1)
2

There is a limitation in synapse about the number of allowed dimensions (which I think is 5)

So even this will fail (with 6 dims):
t.to(‘hpu’).unsqueeze(1).repeat(1, 2, 1, 1, 1, 1)

but this works (with 5 dims)
t.to(‘hpu’).repeat(2, 4, 1, 1, 1)
