Unsupported shape calculation for operator visionFeaturePrint - Converting CoreML to ONNX #354

Open MarcusSjolin opened 4 years ago

Seems to be unsupported

Ran into the same issue, just trying to convert a very simple image classification model. Is this not yet supported in general for CoreML to ONNX?

Im running into this issue still also.

jbrown15 commented 4 years ago

I too, am running into this issue.

codabrink commented 3 years ago

Just ran into this issue today as well.

brown2021 commented 2 years ago

same. Anyone found the fix?

rextremotabaresDtt commented 2 years ago

Hi guys, any update on this? Are these models not suported? If so, how can you export coreml to another format?

thomassantosh commented 2 years ago

Same here, just got the same error converting a basic image classification into ONNX, using onnxmltools.

brown2021 commented 2 years ago

I have been having this issue for over a year now lol. I am looking for a clean way to convert a coreml model to a pytorch

Still not working in 6.0 :(

abhishekwynum commented 1 year ago

Did this receive any fix on the current version ?

brown2021 commented 1 year ago

To my understanding it will never be fixed. I think Apple intentionally stopped supporting their model to be converted. But it has supported the other direction, converting from other libraries to coreML.

To my eyes it looks like we have full access to the model via coremltools so it shouldn't be impossible to write a shape calculator.
