Manual DepthAI installation

In First steps with DepthAI we used installer (either Windows installer, or bash script installer) to install depthai dependencies, download the depthai repository from Github, install its requirements and run the DepthAI demo script. You can also manually perform all these steps, as described below.

Install DepthAI dependencies

Please refer to documentation here to install depthai dependencies.

Download demo script

DepthAI demo is located in depthai repository on Github.

Clone the repository with git

Download repository zip

Git can be used to download (clone) the code, and later easily update it to get all the newest features. Open the terminal session and go to a directory of preference, where you’d like to download DepthAI demo script. Then, run the following command to download the demo script:

$ git clone https://github.com/luxonis/depthai.git
$ cd depthai

First, download a depthai repository from Github - shortcut here. You can then unpack the archive file to a directory of preference.

(Optional) Create python virtualenv

To create and use the virtualenv, you can follow an official python guide to virtualenvs or follow os-specific guides on the web, like “How to Create Python 3 Virtual Environment on Ubuntu 20.04”

This will make sure that you are using a fresh environment and that Python 3 is the default interpreter - this can help to prevent potential issues.

I usually create and use virtualenvs by running

$ python3 -m venv myvenv
$ source myvenv/bin/activate
$ pip install -U pip

And this may require installing these packages prior

$ apt-get install python3-pip python3-venv

Install requirements

Once the demo source code is downloaded and you have your terminal opened in the depthai folder, you can install all additional packages that the DepthAI demo requires (together with the depthai API Python library):

depthai $ python3 install_requirements.py

Afterwards, you can continue with the Default run of the DepthAI demo.
