### Install DeepLabCut-live on a NVIDIA Jetson Development Kit
First, please follow NVIDIA's specific instructions to setup your Jetson Development Kit (see [Jetson Development Kit User Guides](https://developer.nvidia.com/embedded/learn/getting-started-jetson)). Once you have installed the NVIDIA Jetpack on your Jetson Development Kit, make sure all system libraries are up-to-date. In a terminal, run:
```
sudo apt-get update
sudo apt-get upgrade
```
Lastly, please test that CUDA is installed properly by running: `nvcc --version`. The output should say the version of CUDA installed on your Jetson.
#### Install python, virtualenv, and tensorflow
We highly recommend installing DeepLabCut-live in a virtual environment. Please run the following command to install system dependencies needed to run python, to create virtual environments, and to run tensorflow:
```
sudo apt-get update
sudo apt-get install libhdf5-serial-dev \
hdf5-tools \
libhdf5-dev \
zlib1g-dev \
zip \
libjpeg8-dev \
liblapack-dev \
libblas-dev \
gfortran \
python3-pip \
python3-venv \
python3-tk \
curl
```
#### Create a virtual environment
Next, create a virtual environment called `dlc-live`, activate the `dlc-live` environment, and update it's package manger:
```
python3 -m venv dlc-live
source dlc-live/bin/activate
pip install -U pip testresources setuptools
```
#### Install DeepLabCut-live dependencies
First, install python dependencies to run tensorflow (from [NVIDIA instructions to install tensorflow on Jetson platforms](https://docs.nvidia.com/deeplearning/frameworks/install-tf-jetson-platform/index.html)). _This may take ~15-30 minutes._
```
pip3 install numpy==1.16.1 \
future==0.17.1 \
mock==3.0.5 \
h5py==2.9.0 \
keras_preprocessing==1.0.5 \
keras_applications==1.0.8 \
gast==0.2.2 \
futures \
protobuf \
pybind11
```
Next, install tensorflow 1.x. This command will depend on the version of Jetpack you are using. If you are uncertain, please refer to [NVIDIA's instructions](https://docs.nvidia.com/deeplearning/frameworks/install-tf-jetson-platform/index.html#install). To install tensorflow 1.x on the latest version of NVIDIA Jetpack (version 4.4 as of 8/2/2020), please the command below. _This step will also take 15-30 mins_.
```
pip3 install --pre --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v44 'tensorflow<2'
```
Lastly, copy the opencv-python bindings into your virtual environment:
```
cp -r /usr/lib/python3.6/dist-packages ~/dlc-live/lib/python3.6/dist-packages
```
#### Install the DeepLabCut-live package
Finally, please install DeepLabCut-live from PyPi (_this will take 3-5 mins_), then test the installation:
```
pip install deeplabcut-live
dlc-live-test
```
If installed properly, this script will i) download the full_dog model from the DeepLabCut Model Zoo, ii) download a short video clip of a dog, and iii) run inference while displaying keypoints.
