Set Up the Project
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.
Installing Python
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.
You can follow this guide to install it (alternatively, you can google how to install Python 3.8 (or 3.9)
).
Installing Poetry
Poetry
is our package manager. It drastically simplifies dependency and environment management.
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.
Installing Make
The dev tools use make
to launch the various commands.
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:
# check for gmake
which gmake
# If you don't have it, it will error out, install gmake
brew install make
# recheck, now you should have gmake
which gmake
It is possible to install gmake
as make
. Check this StackOverflow post for more info.
On Windows, check this GitHub gist.
Cloning repository
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).
Setting up environment on your host OS
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.
cd concrete-ml
make setup_env
Activating the environment
Finally, all we need to do is to activate the newly created environment using the following command:
macOS or Linux
source .venv/bin/activate
Windows
source .venv/Scripts/activate
Setting up environment on Docker
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:
docker volume ls
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).
# Here we have dev_venv sourced
(dev_venv) dev_user@8e299b32283c:/src$ make setup_env
Leaving the environment
After your work is done, you can simply run the following command to leave the environment:
deactivate
Syncing environment with the latest changes
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!
make sync_env
Troubleshooting your environment
In your OS
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:
# Try to install the env normally
make setup_env
# If you are still having issues, sync the environment
make sync_env
# If you are still having issues on your OS, delete the venv:
rm -rf .venv
# And re-run the env setup
make setup_env
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.
In Docker
Here are the steps you can take in your Docker to try and fix issues:
# Try to install the env normally
make setup_env
# If you are still having issues, sync the environment
make sync_env
# If you are still having issues in Docker, delete the venv:
rm -rf ~/dev_venv/*
# Disconnect from Docker
exit
# And relaunch, the venv will be reinstalled
make docker_start
# If you are still out of luck, force a rebuild which will also delete the volumes
make docker_rebuild
# And start Docker, which will reinstall the venv
make docker_start
If the problem persists at this point, you should ask for help. We're here and ready to assist!
