Type Inference Error of QLinearConv: inputs are expected to have tensor type

[jschauerUdS]

Hello together,

i am quantizing a .onnx model in Python with the quantize_static() function. After creating an ONNX runtime Inference Session the Error:

" File ~\AppData\Roaming\Python\Python38\site-packages\onnxruntime\capi\onnxruntime_inference_collection.py:419 in init
self._create_inference_session(providers, provider_options, disabled_optimizers)

File ~\AppData\Roaming\Python\Python38\site-packages\onnxruntime\capi\onnxruntime_inference_collection.py:463 in _create_inference_session
sess.initialize_session(providers, provider_options, disabled_optimizers)

Fail: [ONNXRuntimeError] : 1 : FAIL : Node (QLinearConv_token_308) Op (QLinearConv) [TypeInferenceError] inputs are expected to have tensor type."

appears.
Does anyone know how to change the input type of a Node or have another idea to solve this problem?

I'm using:
Python: '3.8.10'
ONNX Version: '1.14.1'
ONNX Runtime Version: '1.16.2'
