This is one of the many python layers designed as a part of ABG DNA Veda 2.0 The objectives of this layer are:

• Pick stream information from redis cache
• Read multiple streams continuously, convert them into frames and store these frames in the file system
• Push the frame information to RabbitMQ server

• python3.6
• virtualenv

Upgrade python to python3.6 and make it as the default python:

If you are using Ubuntu 14.04 or 16.04, you can use Felix Krull's deadsnakes PPA at https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa:

sudo add-apt-repository ppa:deadsnakes/ppa

Alternatively, you can use J Fernyhough's PPA at https://launchpad.net/~jonathonf/+archive/ubuntu/python-3.6:

sudo add-apt-repository ppa:jonathonf/python-3.6

sudo apt-get update
sudo apt-get install python3.6

If you are using Ubuntu 16.10 or 17.04, then Python 3.6 is in the universe repository, so you can just run:

sudo apt-get update
sudo apt-get install python3.6

To use python3.6 for virtualenv creation and inside virtualenv use 'python3.6'

Ubuntu 17.10 and 18.04 already come with Python 3.6 as default. Just use python3 to invoke it.

Keep in mind no spaces are there in the project path.

Create and activate a virtualenv: (Make sure to activate virtual environment with python version 3.6)

virtualenv --python=python3 venv
source venv/bin/activate

Install dependencies:

pip3 install -r requirements/local.txt

Edit the environment variables in '.env.template' file and then RENAME the file to '.env'

NOTE: This file has already been added to .gitignore, hence it will not be pushed to your repository. While deployment or using CI tools like travis or circle-ci, you have to take care of setting the environment variables seperately.
