Dataset_Utilities issue saving images

[KatharinaSchmidt]

Hey guys,
first, thank you for providing such great tools. I am currently using ndds for data generation in my master thesis.
I want to visualize the annotated data and tried to use NVDU. If I run "nvdu_viz" in the directory where i saved camer_settings, object_settings and one dataset (including rgb, depth, class segmentation, instance segmentation and the .json file with position and so on) i can see the bounding boxes, etc. in the class-segmentation image. But I can't see the other images with the corrsponding, annotated data.

My second problem is, that i can't export or save the image.
When I try to save images I use the follwing command (on windows 10):
nvdu_viz -e D:\Masterarbeit\NVDU\Ergebnis D:\Masterarbeit\NVDU\Test_dataset

Then I get the follwing in my commandline:
args: Namespace(auto_change=False, auto_export=False, camera_settings_path=None, data_annot_dir='', dataset_dir='D:\\Masterarbeit\\NVDU\\Test_Dataset', export_dir='D:\\Masterarbeit\\NVDU\\Ergebnis', fps=10, ignore_fixed_transform=False, model_dir='d:\\masterarbeit\\nvdu\\dataset_utilities\\nvdu\\data\\ycb\\original', name_filters=['*.png'], object_settings_path=None, size=[0, 0])
name_filters: ['*.png']

Can someone tell me, why no images are saved in the directory I sepcified?
And how can in load the 3d-models? I got my models in .stp and .fbx format available.

Thanks in advance for any help :)
