Hi everyone,
I’m working on a custom dataset using the tutorial   use custom dataset 19.
I’ve have tested (print out) my image annotations and they are all there but I just see the image without annotation overlays using the instruction in the tutorial. Below is the output of an image I’m trying to visualize the annotations. I showed only the first 10 items of the segmentation key.

nb of labels : 3
label 0
bbox : [38, 61, 54, 80]
bbox_mode : 0
category_id : 0
iscrowd : 0
segmentation: [63.5, 62.5, 64.5, 61.5, 66.5, 61.5, 67.5, 62.5, 68.5, 61.5]
label 1
bbox : [64, 85, 62, 61]
bbox_mode : 0
category_id : 1
iscrowd : 0
segmentation: [103.5, 86.5, 104.5, 85.5, 105.5, 85.5, 106.5, 86.5, 107.5, 86.5]
label 2
bbox : [68, 90, 53, 51]
bbox_mode : 0
category_id : 2
iscrowd : 0
segmentation: [92.5, 91.5, 93.5, 90.5, 94.5, 90.5, 95.5, 91.5, 98.5, 91.5]

Some images don’t have my target objects so I set category_id to  num_categories (here 3) to indicate that this image is only background (is my use of it correct ??).
As I work in google colab, I’ve tried to modify the source that prompts when accessing the method definition in order to add some print in the overlay_instances. But nothing appears.
Please how can debug this matter.
Thank you so much.
