IndexError: boolean index did not match indexed array along dimension 2; dimension is 4 but corresponding boolean dimension is 3

When I try to run the following code

from PIL import Image
from surya.ocr import run_ocr
from surya.model.detection import segformer
from surya.model.recognition.model import load_model
from surya.model.recognition.processor import load_processor

IMAGE_PATH = "static\images\excerpt_text.png"
image = Image.open(IMAGE_PATH)
langs = ["en"] # Replace with your languages
det_processor, det_model = segformer.load_processor(), segformer.load_model()
rec_model, rec_processor = load_model(), load_processor()

predictions = run_ocr([image], [langs], det_model, det_processor, rec_model, rec_processor)

I am getting error :

I cannot reproduce this. I ran the exact same code with the latest version, and it worked fine. Can you share the image you're using? Also verify that you're using the latest version of surya.

Actually, try image = image.convert("RGB") before you do run_ocr. I think your image is RGBA

@VikParuchuri
Thanks for the feedback.

It is working after adding image = image.convert("RGB") in the code.

Fixed this in the latest release
