jikechao opened a new issue, #14926:
URL: https://github.com/apache/tvm/issues/14926

   For the layer `InstanceNorm1d` or `InstanceNorm3d`, if attribute 
`track_running_stats` was set as `True`, TVM will give different inference 
results with PyTorch.
   
   ### Expected behavior
   For the same input data, TVM and PyTorch give the same inference results.
   
   ### Actual behavior

   ### Steps to reproduce
   ```
   import torch
   from tvm import relay
   import tvm
   import numpy as np
   
   m = torch.nn.InstanceNorm1d(3, track_running_stats=True).eval()
   input_data = [torch.randn([1, 3, 5], dtype=torch.float32)]
   
   torch_outputs = m(*[input_.clone() for input_ in input_data ])
   trace = torch.jit.trace(m, input_data)
   input_shapes = [('input0', torch.Size([1,3,5]))]
   
   mod, params = relay.frontend.from_pytorch(trace, input_shapes)
   
   with tvm.transform.PassContext(opt_level=3):
       exe = relay.create_executor('aot', mod=mod, params=params, 
device=tvm.cpu(0), target='llvm').evaluate()
   input_tvm = {'input0': np.array(input_data[0], dtype='float32')}
   tvm_outputs = exe(**input_tvm).asnumpy()
   
   np.testing.assert_allclose(torch_outputs, tvm_outputs, rtol=1e-3, atol=1e-3)
   ```
   
   ### Triage
