Instance Segmentation Using TAO

Instance segmentation is a popular computer vision technique that can identify each instance of multiple objects in a frame at the pixel level. Instance segmentation will not only produce bounding boxes around the object, but also segmentation masks. This model card contains pretrained weights that may be used as a starting point with the following instance segmentation networks in Train Adapt Optimize (TAO) Toolkit to facilitate transfer learning.

Following instance segmentation architecture are supported:

• MaskRCNN

The pre-trained weights are trained on a subset of the Google OpenImages dataset. Following backbones are supported with these MaskRCNN networks.

• resnet10/resnet18/resnet34/resnet50/resnet101

To see the full list of all the backbones, scroll over to the version history tab.

Note: These are unpruned models with just the feature extractor weights, and may not be used without re-training in an Instance segmentation application

Training Instance Segmentation Models Using TAO

The instance segmentation apps in TAO expect data in COCO format. TAO provides a simple command line interface to train a deep learning model for instance segmentation.

The models in this model area are only compatible with TAO Toolkit. For more information about using this model with TAO, please view the instructions here to install the TAO Launcher CLI and use with the instance segmentation trainer in TAO.

1. Install the NGC CLI from ngc.nvidia.com

2. Configure the NGC CLI using the following command

ngc config set

3. To view all the backbones that are supported by Instance segmentation architecture in TAO:

   ngc registry model list nvidia/tao/pretrained_instance_segmentation:*
   

4. Download the model:

   ngc registry model download-version nvidia/tao/pretrained_instance_segmentation:<template> --dest <path>
   

Instructions to run the sample notebook

1. Get the NGC API key from the SETUP tab on the left. Please store this key for future use. Detailed instructions can be found here

2. Configure the NGC command line interface using the command mentioned below and follow the prompts.

ngc config set

3. Download the sample notebooks from NGC using the command below

ngc registry resource download-version "nvidia/tao_cv_samples:v1.0.2"

3. Invoke the jupyter notebook using the following command

   jupyter notebook --ip 0.0.0.0 --port 8888 --allow-root
   

4. Open an internet browser and type in the following URL to start running the notebooks when running on a local machine.

   http://0.0.0.0:8888
   

   If you wish to run view the notebook from a remote client, please modify the URL as follows:

   http://a.b.c.d:8888
   

   Where, the a.b.c.d is the IP address of the machine running the container.
