[QUESTION] Emulator: to which precision is this consider correct ?

[3outeille]

Hi, I was running the test_all_reduce which fails because the tensors are not similar enough after around 7 digits. Is this an expected behavior ? or do we want exact matching value ?

torch.set_printoptions(precision=10)

ground_truth[torch_rank]
tensor([ 2.1518430710, -3.1110968590, -3.0482885838, -0.1535055935,
