[GitHub] [tvm] shingjan opened a new issue, #12922: [Bug] Relay/TOPI `adv_index` not supporting `None` as arguments

[GitBox <gi...@apache.org>]

shingjan opened a new issue, #12922:
URL: https://github.com/apache/tvm/issues/12922

   The advanced indexing implementation of relay/topi is not able to handle cases that use None as one of the indexinf=g argument.
   
   ### My repro under `test_forward_index`
   ```
       class Index2(Module):
           def forward(self, x):
               return x[None, [2, 2]]
   
       input_data = torch.rand([3, 3, 3, 3]).float().cpu()
       verify_model_with_input(Index2().eval(), [input_data])
   ```
   
   ### Expected behavior
   
   A tensor shaped `[1, 2, 3, 3, 3]` shall be returned.
   
   ### Actual behavior
   ```
   >           raise Exception("warning unhandled case: {0}".format(type(expr)))
   E           Exception: warning unhandled case: <class 'NoneType'>
   
   python/tvm/relay/expr_functor.py:76: Exception
   ```
   ### Environment
   
   Latest TVM main
