Issue with custom OCR model

[DJay921]

This is my code that I'm using. The issue is that I'm not seeing any tables returned and no errors, however all the print statements in the code below seem to be executing fine and I'm seeing the OCR results of the document. I'm passing my custom model to the object at the time of instantiating the class.

        with NamedTemporaryFile(suffix='.jpg', delete=False) as tmp_f:
            tmp_file = tmp_f.name
            # Write image to temporary file
            cv2.imwrite(tmp_file, image)

            # Get OCR
            ocr_result = self.ocr(tmp_file)

        # Remove temporary file
        while os.path.exists(tmp_file):
            try:
                os.remove(tmp_file)
            except PermissionError:
                pass

        # Get result
        print("OCR RESULT", ocr_result)
        # ocr_result = ocr_result.pop()
        return [[bbox, word, round(conf, 2)] for bbox, word, conf in ocr_result[0]] if ocr_result else []
