Onnx Text Recognition (OnnxTR) is an Onnx-wrapped version of docTR that provides high-performance OCR on documents. It supports text detection, recognition, and end-to-end OCR pipelines using pre-trained models exported to ONNX. Current version 0.8.1 requires Python >=3.10 and <4. Release cadence is irregular.

OCRPredictor

✓ from onnxtr import OCRPredictor

✗ from onnxtr import OCRPredictor

Basic usage of onnxtr to perform OCR on an image and print the recognized text.

from onnxtr import OCRPredictor from doctr.io import DocumentFile # Initialize predictor with detection + recognition models predictor = OCRPredictor( det_arch='db_resnet50', reco_arch='crnn_vgg16_bn', pretrained=True ) # Load a document image doc = DocumentFile.from_images("path/to/image.jpg") # Perform OCR result = predictor(doc) print(result.render())

Debug

Known issues

breakingonnxtr 0.8.0+ requires Python >=3.10; Python 3.9 is not supported.

fix

Upgrade Python to 3.10 or later; or use onnxtr<0.8.0 (not recommended).

affects: >=0.8.0

gotchaInput images must be RGB, not BGR (openCV default). onnxtr reads images as RGB by default via docTR's DocumentFile, but using openCV directly and then converting may cause color issues.

fix

Use DocumentFile.from_images() or ensure image is converted to RGB: cv2.cvtColor(img, cv2.COLOR_BGR2RGB).

affects: all

deprecatedThe standalone OnnxTR model export tools are deprecated; use docTR's native ONNX export instead.

fix

Use docTR's onnx_export utilities. See docTR documentation.

affects: >=0.7.0
