[HELP!] How to avoid TVM increase the tensor dimensions?

I use the TVM to refine my onnx model which max dimensionality of tensor that flow on model is < 4-dim, but get 5-dim tensor on the new onnx model from TVM, this means that TVM increases the tensor dimensions that flow in the model.

Are there any parameters in TVM such as MAX_TENSOR_DIM or others that control the tensor dimensions?

thanks
