Installation

Docker

This is already included in the deps image and other images that use it as a base image.

Mac

1. To setup python on macOS using Homebrew, first install Homebrew if you haven't already. Then, install Python by running:

``sh
brew install python
`

2. Homebrew's python formula now points to Python 3 by default. Verify that python3 is installed by running:

`sh
python3 --version
`

3. Check if you have a python virtual env
by running python3 -V, if not you can create one by running

`sh
python3 -m venv ~/pppython
source ~/pppython/bin/activate

check the installed path

which python3

Gives the absolute path to the python installattion in the virtual environment

`

4. Now you should be able to install all the relevant python modules by installing all modules in the requirement.txt file

`sh
pip3 install -r requirements.txt


5. In order for the nodejs server code to use python virtual environment
that has been set up, you can do one of the following:

- a. set a serverconfig.python option that equals the absolute path to your .venv/bin/python3 installation
- b. call source path/to/.venv/bin/activate in the same shell or terminal tab/window before running a package script
like npm run dev , npm run test:integration, etc.

6. Once Python development and testing are finished, execute the following command from the proteinpaint/python directory to deactivate the currently active virtual environment:

`sh
source .venv/bin/deactivate
``

This is important to keep the GitHub hook working.
