Please try specifying optimized_model_filepath in SessionOption.
https://onnxruntime.ai/docs/api/python/api_summary.html#:~:text=property-,optimized_model_filepath,-%23

[fengyuentau]

Could you also give an example how to use these options?

[justinchuby]

In the documentation linked above there is

options = onnxruntime.SessionOptions()
options.optimized_model_filepath = "optimized.onnx"
session = onnxruntime.InferenceSession(
    'model.onnx',
    sess_options=options,
    providers=['CUDAExecutionProvider', 'CPUExecutionProvider']
)

Thank you all for the help.

@justinchuby There is an extra parenthesis ")" in the end of your example.

Also worth mentioning that default options.graph_optimization_level is ort.GraphOptimizationLevel.ORT_ENABLE_ALL.
