[GitHub] [tvm] mkroening opened a new issue #9657: [Bug] [TVMC] tune: ZeroDivisionError on Add

mkroening opened a new issue #9657:
URL: https://github.com/apache/tvm/issues/9657


   ### Expected behavior
   
   No issue when running
   
   ```console
   tvmc tune --target llvm --output autotuner_records.json model.onnx
   ```
   
   with the ONNX model only being an addition of two single values.
   Note that compiling the model without tuning works and produces valid results.
   
   Model:
   
   ```onnx
   ir_version: 8
   graph {
     node {
       input: "A"
       input: "B"
       output: "C"
       op_type: "Add"
     }
     name: "test-model"
     input {
       name: "A"
       type {
         tensor_type {
           elem_type: 1
           shape {
             dim {
               dim_value: 1
             }
           }
         }
       }
     }
     input {
       name: "B"
       type {
         tensor_type {
           elem_type: 1
           shape {
             dim {
               dim_value: 1
             }
           }
         }
       }
     }
     output {
       name: "C"
       type {
         tensor_type {
           elem_type: 1
           shape {
             dim {
               dim_value: 1
             }
           }
         }
       }
     }
   }
   opset_import {
     version: 15
   }
   ```
   
   ### Actual behavior
   
   ```
   # [..]

       trials = int(trials / len(tasks))
   ZeroDivisionError: division by zero
   ```
   
   ### Environment
   
   Operating System: Ubuntu 20.04.3 LTS
   TVM version: ccd59e89d21cc81cc06f2a16cddcc1ffeed1e2a1
   
   ### Steps to reproduce
   
   Create `model.onnx` with:
   
   ```python
   import onnx
   from onnx import helper
   from onnx import TensorProto
   
   l = 1
   
   A = helper.make_tensor_value_info('A', TensorProto.FLOAT, [l])
   B = helper.make_tensor_value_info('B', TensorProto.FLOAT, [l])
   
   C = helper.make_tensor_value_info('C', TensorProto.FLOAT, [l])
   
   node_def = helper.make_node(
       'Add',         # name
       ['A', 'B'],     # inputs
       ['C'],          # outputs
   )
   
   graph_def = helper.make_graph(
       [node_def],     # nodes
       'test-model',   # name
       [A, B],         # inputs
       [C],            # outputs
   )
   
   model_def = helper.make_model(graph_def)
   
   print('The model is:\n{}'.format(model_def))
   onnx.checker.check_model(model_def)
   print('The model is checked!')
   
   onnx.save(model_def, 'model.onnx')
   ```
   
   Thanks a lot for your help! :)

   @mkroening, thanks for the bug report.
   
   cc @comaniac @junrushao1994 any idea on who can help us with this one, apart from the obvious patch on tvmc to only do that calculation if `len(tasks) > 0`, I was thinking on whether there is something on the ONNX frontend or autotvm to. be fixed?
