[Inductor] [CPU] GroupNorm triggers inconsistency when using Inductor #141541
Description
🐛 Describe the bug
GroupNorm does not seem to be optimized correctly, I think this is related to #129823
I can provide the reproduction.
BTW, it only prints False on cpu.
Although the error on cuda is not 0, it is within the tolerance range of torch.allclose
import torch
import torch.nn as nn
torch.manual_seed(0)
class Model(nn.Module):
def __init__(self):
super().__init__()
self.gn = nn.GroupNorm(num_groups=32, num_channels=32)
def forward(self, x):
x = self.gn(x)
return x
model = Model().eval()
c_model = torch.compile(model)
x = torch.randn(1, 32, 128, 128, 128)
inputs = [x]
output = model(*inputs)
c_output = c_model(*inputs)
print(torch.max(torch.abs(output - c_output)))
print(torch.allclose(output, c_output, 1.3e-6, 1e-5))Error logs
on CPU
tensor(7.0095e-05, grad_fn=<MaxBackward1>)
False
on CUDA
tensor(1.4305e-06, device='cuda:0', grad_fn=<MaxBackward1>)
True
