Run adaround failed with a toy onnx model

[pycoco]

when i try to quant a model with adaround. But below error occurs:

onnxruntime.capi.onnxruntime_pybind11_state.InvalidGraph: [ONNXRuntimeError] : 10 : INVALID_GRAPH : This is an invalid model. Type Error: Type 'tensor(uint8)' of input parameter (input) of operator (QuantizeLinear) in node (QuantizeLinear0) is invalid.

This is because the 'input' variable is of type uint8, and the quantization operator we use in Dipoorlet is quantizelinear-13（ https://github.com/onnx/onnx/blob/main/docs/Changelog.md#quantizelinear -13) . It only supports input tensor types of int32 and float, so I suggest you change the input to int32 or float before trying again.

ok, thanks very much
