Failed to convert tensorflow model to onnx

[jeyong8217]

After installing onnx and onnxruntime, I’m trying to convert my custom tensorflow model with 1D CNN to onnx.

While I run the code os.system("python -m tf2onnx.convert --saved-model tf_model --output model.onnx"), I get output “256”…

I searched information as many as I can but still got the same error…

I really need your advices…

Could you share the complete output log with us?

Thanks.

I downgraded tf2onnx from 1.14.0 to 1.9.3 which is compatible for tensorflow 2.7.0
