Fix pytorch 2.6 bug

Fix bug that caused issues on MPS (Mac) devices when using pytorch 2.6.

Pin pytorch

Pytorch 2.6.0 doesn't work well with some of the models on MPS (Mac), so pinning to the old version.

Fix cli script issue

Fix issue with cli scripts and folders.

Better polygon type checking

Improve how polygons are type checked in the schema.

Fix rowspan bug

Fixes a bug where rowspans weren't included in table model predictions.

Refactor surya; new table recognition model

Refactor

This is a complete refactor of surya - the code is now cleaner and better organized. Models are now imported and used differently, here is an example for OCR:

from PIL import Image
from surya.recognition import RecognitionPredictor
from surya.detection import DetectionPredictor

image = Image.open(IMAGE_PATH)
langs = ["en"] # Replace with your languages or pass None (recommended to use None)
recognition_predictor = RecognitionPredictor()
detection_predictor = DetectionPredictor()

predictions = recognition_predictor([image], [langs], detection_predictor)

See the README for how to use other models.

Table recognition

There is a new table recognition model which detects colspans/rowspans better, along with header cells. It also isn't as complex to use, since it operates on just the images versus the images and bboxes.

What's Changed

• Layout improvements by @VikParuchuri in #267
• New table model; total refactor by @VikParuchuri in #279
• Add ci workflow by @VikParuchuri in #284

Full Changelog: v0.8.3...v0.9.0

Pin pypdfium2

Pin pypdfium2 version - newest version can cause issues.

New layout model

Layout model is twice as fast and more accurate.

What's Changed

• Update layout model by @VikParuchuri in #270

Full Changelog: v0.8.1...v0.8.2

Add bad OCR detection model

• Add a model to detect bad OCR text
• Add top_k predictions to layout
• Add in test suite

What's Changed

• Add OCR Error Detection Model by @tarun-menta in #261
• Add top_k to Surya Layout and Fix Confidence Value Issue by @iammosespaulr in #263
• Bad OCR detection model by @VikParuchuri in #268

New Contributors

• @tarun-menta made their first contribution in #261
