Training Semantic Segmentation Models Using TAO

The semantic segmentation apps in TAO expect mask data as encoded images with every pixel assigned to the class label. TAO provides a simple command line interface to train a deep learning model for semantic 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 semantic segmentation trainer in TAO.

Before running the container, use docker pull to ensure an up-to-date image is installed. Once the pull is complete, you can run the container image.

\n
Install the NGC CLI from ngc.nvidia.com
\n
\n
Configure the NGC CLI using the following command
\n

ngc config set\n

\n
To view all the backbones that are supported by Instance segmentation architecture in TAO:
\n
```
ngc registry model list nvidia/tao/pretrained_semantic_segmentation:*\n
```
\n

Download the model:

--dest \n\">

ngc registry model download-version nvidia/tao/pretrained_semantic_segmentation:<template> --dest <path>\n

Instructions to run the sample notebook

\n
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
\n
\n
Configure the NGC command line interface using the command mentioned below and follow the prompts.
\n
```
ngc config set\n
```
\n

Download the sample notebooks from NGC using the command below

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

Invoke the jupyter notebook using the following command

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

\n
Open an internet browser and type in the following URL to start running the notebooks when running on a local machine.
\n
```
http://0.0.0.0:8888\n
```
\n
If you wish to run view the notebook from a remote client, please modify the URL as follows:
\n
```
http://a.b.c.d:8888\n
```
\n
Where, the a.b.c.d is the IP address of the machine running the container.
