Running Image classification Models Using TAO

The image classification apps in TAO expect data in KITTI file format. TAO provides a simple command line interface to train a deep learning model for image classification.

The models in this model area are only compatible with TAO Toolkit. For more information about TAO please refer to the Getting Started Guide.

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 for classification that are supported by TAO:

ngc registry model list nvidia/tao_pretrained_classification:*

4. Download the model:

ngc registry model download-version nvidia/tao_pretrained_classification:<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"

4. Invoke the jupyter notebook using the following command

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

5. 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.
