You will need to first install Python. This can be done automatically for Linux with the rest of the dependencies running the script indicated below with the --linux-install-python flag. If you want to install some of the dependencies manually, we detail the installations of Poetry and Make.
On Linux and macOS you will have to run the script in ./script/make_utils/setup_os_deps.sh. Specify the --linux-install-python flag if you want to install python3.8 as well on apt-enabled Linux distributions. The script should install everything you need for Docker and bare OS development (you can first check the content of the file to check what it will do).
It is strongly recommended to use the development Docker (see the docker guide). However, our helper script should bring all the tools you need to develop directly on Linux and macOS.
For Windows see the Warning admonition below.
The project targets Python 3.8 through 3.9 inclusive.
For Windows users, the setup_os_deps.sh script does not install dependencies because of how many different installation methods there are/lack of a single package manager.
The first step is to install Python (as some of our dev tools depend on it), then Poetry. In addition to installing Python, you are still going to need the following software available on path on Windows, as some of our basic dev tools depend on them:
Development on Windows only works with the Docker environment. Follow this link to setup the Docker environment.
Concrete ML is a Python library, so Python should be installed to develop Concrete ML. v3.8 and v3.9 are the only supported versions.
As stated at the start of this document, you can install Python 3.8 for Linux automatically if it's available in your distribution's apt repository using the ./script/make_utils/setup_os_deps.sh script.
You can follow this guide to install it (alternatively, you can google how to install Python 3.8 (or 3.9)).
Poetry is our package manager. It drastically simplifies dependency and environment management.
As stated at the start of this document, you can install Poetry for macOS and Linux automatically using the ./script/make_utils/setup_os_deps.sh script.
You can follow this official guide to install it.
As there is no concrete-compiler package for Windows, only the dev dependencies can be installed. This requires Poetry >= 1.2.
At the time of writing (March 2022), there is only an alpha version of Poetry 1.2 that you can install. Use the official installer to install preview versions.
The dev tools use make to launch the various commands.
As stated at the start of this document, you can install make for macOS and Linux automatically if it's available in your distribution's apt repository using the ./script/make_utils/setup_os_deps.sh script.
On Linux, you can install make from your distribution's preferred package manager.
On macOS, you can install a more recent version of make via brew:
It is possible to install gmake as make. Check this StackOverflow post for more info.
On Windows, check this GitHub gist.
In the following sections, be sure to use the proper make tool for your system: make, gmake, or other.
Now, it's time to get the source code of Concrete ML.
Clone the code repository using the link for your favourite communication protocol (ssh or https).
We are going to make use of virtual environments. This helps to keep the project isolated from other Python projects in the system. The following commands will create a new virtual environment under the project directory and install dependencies to it.
The following command will not work on Windows if you don't have Poetry >= 1.2.
Finally, all we need to do is to activate the newly created environment using the following command:
Docker automatically creates and sources a venv in ~/dev_venv/
The venv persists thanks to volumes. We also create a volume for ~/.cache to speed up later reinstallations. You can check which Docker volumes exist with:
You can still run all make commands inside Docker (to update the venv, for example). Be mindful of the current venv being used (the name in parentheses at the beginning of your command prompt).
After your work is done, you can simply run the following command to leave the environment:
From time to time, new dependencies will be added to the project or the old ones will be removed. The command below will make sure the project has the proper environment. So run it regularly!
If you are having issues, consider using the dev Docker exclusively (unless you are working on OS specific bug fixes or features).
Here are the steps you can take on your OS to try and fix issues:
At this point, you should consider using Docker as nobody will have the exact same setup as you. If, however, you need to develop on your OS directly, you can ask us for help but may not get a solution right away.
Here are the steps you can take in your Docker to try and fix issues:
If the problem persists at this point, you should ask for help. We're here and ready to assist!
