[1] Clip: Only support converting clip(0, 6) to Relu6.

[2] Pow: Only support the form where the exponent is a single constant.

[3] Sum and Max: Only support 2 inputs.

[4] Operators supported by converter but do not require specific implementation. Generally, such operators are optimized by the conversion tool, such as being merged or replaced by other operators.
