❓Question

Is there any method for printing converted operation shape during converting?

I converted to .mlmodel, but the model doesn't have output shapes. So I want to inspect which operation was incorrectly converted.

In 3.x coremltools, I can see all shapes each operation. But in 4.0b1, I cannot see it anymore and coremltools only shows the progress status.

Is it possible to implement an overlay to show where the qrcode is in the camera feed? just like this https://www.appcoda.com/barcode-reader-swift/

Was wondering how can I get the videoPreviewLayer of the camera so I can use transformedMetadataObject
