🐛 libpng error: Write Error in instance_segmentation with COCO

[jpainam]

Hi, this is my code.

from clodsa.augmentors.augmentorFactory import createAugmentor
from clodsa.transformers.transformerFactory import transformerGenerator
from clodsa.techniques.techniqueFactory import createTechnique

PROBLEM = "instance_segmentation"
ANNOTATION_MODE = "coco"
INPUT_PATH = "/home/fst/data/VOCdevkit/VOC2007/JPEGImages"
GENERATION_MODE = "linear"
OUTPUT_MODE = "coco"
OUTPUT_PATH = "/home/fst/data/augmented/"

augmentor = createAugmentor(PROBLEM, ANNOTATION_MODE, OUTPUT_MODE,
                            GENERATION_MODE, INPUT_PATH,
                            {"outputPath": OUTPUT_PATH}
                            )
transformer = transformerGenerator(PROBLEM)

'''for angle in [90, 180]:
    rotate = createTechnique("rotate", {"angle": angle})
    augmentor.addTransformer(transformer(rotate))
'''
flip = createTechnique("flip", {"flip": 1})
augmentor.addTransformer(transformer(flip))
none = createTechnique("none", {})
augmentor.addTransformer(transformer(none))
augmentor.applyAugmentation()

When i run, i get this error

I updated libpng as describe in this StackOverflow link and

x = cv2.imread('img.png')
cv2.imwrite('./new_img.png', x)

give no errors. Please, what might be the problem? Thank you.
