.NET onnxruntime Protobuf parsing failed about onnxruntime HOT 6 OPEN

How large is your model? Can you share it via a file sharing service?

from onnxruntime.

Here is the model:
https://www.transfernow.net/dl/20240329yKmybLR9

from onnxruntime.

C# code does not parse protobuf. It is parsed by google library. I will investigate if we could make it a better error message. Said that, here is some python code that also runs onnx library checker and points to a problem with the model even before InferenceSession is invoked.

import onnxruntime
import numpy as np
import onnx

model_path='model.onnx'

model = onnx.load(model_path)
onnx.checker.check_model(model)

session_options = onnxruntime.SessionOptions()
session_options.log_severity_level = 4
session_options.enable_mem_reuse = False
sess = onnxruntime.InferenceSession(
    model,
    sess_options=session_options,
    providers=["CPUExecutionProvider"],
)

LayerNormalization op appeared in ONNX starting with opset 17.

Your model imports ONNX domain opset11

from onnxruntime.

I will check with the converter folks to see what may have gone wrong.
