AttributeError: 'list' object has no attribute 'values'

As described in the balloon example, I've used VIA tool to annotate my images. I've used circles, polygons, etc. and gave each class its respective name.

Now that I want to load the dataset, using your code, and I get the following error:

Traceback (most recent call last):
  File "components.py", line 522, in <module>
    train(model)
  File "components.py", line 231, in train
    dataset_train.load_components(args.dataset, "train")
  File "components.py", line 124, in load_components
    polygons = [r['shape_attributes'] for r in a['regions'].values()]
AttributeError: 'list' object has no attribute 'values'

What could be the problem? Has anyone tried loading the annotated data which contains circles? (not only polygons)

P.S: Here is the code snippet (taken from surgery.py) to load the data.

# Add images
        for a in annotations:
            # Get the x, y coordinaets of points of the polygons that make up
            # the outline of each object instance. There are stored in the
            # shape_attributes (see json format above)
            polygons = [r['shape_attributes'] for r in a['regions'].values()]
            names = [r['region_attributes'] for r in a['regions'].values()]
            # load_mask() needs the image size to convert polygons to masks.
            # Unfortunately, VIA doesn't include it in JSON, so we must read
            # the image. This is only managable since the dataset is tiny.
            image_path = os.path.join(dataset_dir, a['filename'])
            image = skimage.io.imread(image_path)
            height, width = image.shape[:2]

            self.add_image(
                "components",
                image_id=a['filename'],  # use file name as a unique image id
                path=image_path,
                width=width, height=height,
                polygons=polygons,
                names=names)

It's because the loader only accepts polygons, which is quite bad, tbh.

i have polylines would it still not work. What is the other way to load any idea

[eyildiz-ugoe]

No, it has to be polygons. And it has been long time so I kinda lost my touch to that project, sorry, can't help further I am afraid.

Thank you.
