Train Instance Segmentation Model with Detectron2 | Tutorial | Custom Dataset | Google Colab

Detectron2 is a popular PyTorch based modular computer vision model library. It is the second iteration of Detectron, originally written in Caffe2. The Detectron2 system allows you to plug in custom state of the art computer vision technologies into your workflow.

Thanks for great video I just have one doubt, don't we need to normalize the custom data and its bounding box before using it?

[rohanchumun]

Can I use Object Detection(Bounding Box) instead of Instance Segmentation for Detectron2 ?

[hoinhtrieu]

Is there any change of code while my data just have 1 class? I can't visualize the predict mask btw

CUDA error: device-side assert triggered
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.

i got error like this, what should i do sir?thank you

Hi can anyone tell me how to chose which yaml file is best suitable for our model?

[abckoko]

When I use this code


# Look at training curves in tensorboard:
%load_ext tensorboard
%tensorboard --logdir $OUTPUT_DIR_PATH



It got error 403.
How can I fix it?

Why would you use Detectron2 over YoloV8 or Mask_RCNN? - I'm still a bit confused about the advantages of Detectron2 over the rest.

[bahubalipatil]

how can we get approx size of the object? or is there any way to do it? can it be done while labelling the images if yes then how?

[shariqansari]

I am getting error ;

AttributeError: Cannot find field 'gt_masks' in the given Instances!

can you please suggest how to solve it .

[lofihavensongs]

Hi, great video, and works for me, generally which one is better for object detectron, Detectronv2 or YOLOv8?

[rajivpannuri]

Hi can you please tell me how to use this trained model to detect the objects from fresh images?

[body]

please make video about training detectron2 projects like VITDet

[py]

I would like to know how to create a Confusion matrix. please.
