Quick start

requirements

You need Python installed on your computer (version 3.7 or higher). Refer to this guide if you need help.

Quickstart Using init script (Linux & Mac)

Octopus Sensing comes with a script that helps you quickly start a project. It uses Pipenv to create a virtual environment in order to keep everything clean. It will also create a sample application.

mkdir my-awesome-project
cd my-awesome-project
curl --output init.sh https://raw.githubusercontent.com/nastaran62/octopus-sensing/master/init_script/init.sh
# It's a good idea to read any script before executing it.
bash ./init.sh
rm ./init.sh

The created main.py file is an example application. To run it:

pipenv run python main.py

If you don’t want to use the script, you can use the following methods instead.

Pre-requirements

If you’re using Gnu/Linux, you need to install a few packages on your machine. On an Ubuntu distro, run:

sudo apt-get install libcairo2-dev libgirepository1.0-dev gstreamer-1.0

Installation using Pipenv (All Platforms)

We recommend using a package manager like Pipenv instead of globally installing Octopus Sensing using pip to prevent package conflicts. To do so, follow these commands. (This is same as what the above script does.)

mkdir my-awesome-project
cd my-awesome-project
# Or replace it with your python version
pipenv --python python3.8
pipenv install octopus-sensing

It installs Octopus Sensing inside the virtual environment created by Pipenv. You need to use pipenv to run your code. For example:

pipenv run python main.py

Refer to Pipenv website for more info.

Installation using pip (All Platforms)

You can use pip to install octopus-sensing as simple as:

pip3 install octopus-sensing

(You might need to replace pip3 with pip depending on your system.)

Then it can be imported like:

import octopus_sensing

Installation from source (All Platforms)

If you want to compile it from source for development purposes or to have the un-released features, please refer to Development.

Troubleshooting

  • Pip cannot install PyGObject on Windows. If users want to use octopus-sensing.stimuli or octopus-sensing.windows packages, they need to install it manually themselves. See PyGObject documentation to know how to install PyGObject on Windows.

  • If you saw Namespace Gst not available (or similar) while importing octopus_sensing.stimuli package, you need to install gstreamer package on your machine. On Ubuntu run sudo apt-get install gstreamer-1.0.
