Project description

TAO Toolkit Quick Start Guide

This page provides a quick start guide for installing and running TAO Toolkit.

Requirements

Hardware

The following system configuration is recommended to achieve reasonable training performance with TAO Toolkit and supported models provided:

  • 32 GB system RAM
  • 32 GB of GPU RAM
  • 8 core CPU
  • 1 NVIDIA GPU
  • 100 GB of SSD space

TAO Toolkit is supported on A100, V100 and RTX 30x0 GPUs.

Software Requirements

Software Version
Ubuntu 18.04 LTS 18.04
python >=3.6.9
docker-ce >19.03.5
docker-API 1.40
nvidia-container-toolkit >1.3.0-1
nvidia-container-runtime 3.4.0-1
nvidia-docker2 2.5.0-1
nvidia-driver >465
python-pip >21.06
python-dev

Installing the Pre-requisites

The tao-launcher is strictly a python3 only package, capable of running on python 3.6.9 or 3.7.

  1. Install docker-ce by following the official instructions.

    Once you have installed docker-ce, follow the post-installation steps to ensure that the docker can be run without sudo.

  2. Install nvidia-container-toolkit by following the install-guide.

  3. Get an NGC account and API key:

    a. Go to NGC and click the TAO Toolkit container in the Catalog tab. This message is displayed: Sign in to access the PULL feature of this repository. b. Enter your Email address and click Next, or click Create an Account. c. Choose your organization when prompted for Organization/Team. d. Click Sign In.

  4. Log in to the NGC docker registry (nvcr.io) using the command docker login nvcr.io and enter the following credentials:

      a. Username: $oauthtoken
      b. Password: YOUR_NGC_API_KEY
    

    where YOUR_NGC_API_KEY corresponds to the key you generated from step 3.

DeepStream 6.0 - NVIDIA SDK for IVA inference is recommended.

Installing TAO Toolkit

TAO Toolkit is a Python pip package that is hosted on the NVIDIA PyIndex. The package uses the docker restAPI under the hood to interact with the NGC Docker registry to pull and instantiate the underlying docker containers. You must have an NGC account and an API key associated with your account. See the Installation Prerequisites section for details on creating an NGC account and obtaining an API key.

  1. Create a new virtualenv using virtualenvwrapper.

    You may follow the instructions in this link to set up a Python virtualenv using a virtualenvwrapper.

    Once you have followed the instructions to install virtualenv and virtualenvwrapper, set the Python version in the virtualenv. This can be done in either of the following ways:

    • Defining the environment variable called VIRTUALENVWRAPPER_PYTHON. This variable should point to the path where the python3 binary is installed in your local machine. You can also add it to your .bashrc or .bash_profile for setting your Python virtualenv by default.

      export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
      
    • Setting the path to the python3 binary when creating your virtualenv using the virtualenvwrapper wrapper

      mkvirtualenv launcher -p /path/to/your/python3
      

    Once you have logged into the virtualenv, the command prompt should show the name of your virtual environment

    (launcher) py-3.6.9 desktop:
    

    When you are done with you session, you may deactivate your virtualenv using the deactivate command:

    deactivate
    

    You may re-instantiate this created virtualenv env using the workon command.

    workon launcher
    
  2. Install the TAO Launcher Python package called nvidia-tao.

    pip3 install nvidia-tao
    

    If you had installed an older version of :code:nvidia-tao launcher, you may upgrade to the latest version by running the following command.

    pip3 install --upgrade nvidia-tao
    
  3. Invoke the entrypoints using the :code:tao command.

    tao --help
    

    The sample output of the above command is:

    usage: tao [-h]
             {list,stop,info,augment,bpnet,classification,detectnet_v2,dssd,emotionnet,faster_rcnn,fpenet,gazenet,gesturenet,
             heartratenet,intent_slot_classification,lprnet,mask_rcnn,punctuation_and_capitalization,question_answering,
             retinanet,speech_to_text,ssd,text_classification,converter,token_classification,unet,yolo_v3,yolo_v4,yolo_v4_tiny}
             ...
    
    Launcher for TAO
    
    optional arguments:
    -h, --help            show this help message and exit
    
    tasks:
          {list,stop,info,augment,bpnet,classification,detectnet_v2,dssd,emotionnet,faster_rcnn,fpenet,gazenet,gesturenet,heartratenet
         ,intent_slot_classification,lprnet,mask_rcnn,punctuation_and_capitalization,question_answering,retinanet,speech_to_text,
         ssd,text_classification,converter,token_classification,unet,yolo_v3,yolo_v4,yolo_v4_tiny}  
    

    Note that under tasks you can see all the launcher-invokable tasks. The following are the specific tasks that help with handling the launched commands using the TAO Launcher:

    • list
    • stop
    • info

    When installing the TAO Toolkit Launcher to your host machine's native python3 as opposed to the recommended route of using virtual environment, you may get an error saying that tao binary wasn't found. This is because the path to your tao binary installed by pip wasn't added to the PATH environment variable in your local machine. In this case, please run the following command:

    export PATH=$PATH:~/.local/bin
    

Running the TAO Toolkit

Information about the TAO Launcher CLI and details on using it to run TAO supported tasks are captured in the TAO Toolkit Launcher section of the TAO Toolkit User Guide.
