Lab requires Python 3.6+ and Linux (e.g., Ubuntu). We recommend installing Lab in a Python virtual environment. This has the advantage that there are no modifications to the system-wide configuration, and that you can create multiple environments with different Lab versions (e.g., for different papers) without conflicts:
# Install required packages, including virtualenv. sudo apt install python3 python3-venv # Create a new directory for your experiments. mkdir experiments-for-my-paper cd experiments-for-my-paper # If PYTHONPATH is set, unset it to obtain a clean environment. unset PYTHONPATH # Create and activate a Python 3 virtual environment for Lab. python3 -m venv --prompt my-paper .venv source .venv/bin/activate # Install Lab in the virtual environment. pip install -U pip wheel pip install lab # or preferably a specific version with lab==x.y # Store installed packages and exact versions for reproducibility. # Ignore pkg-resources package (https://github.com/pypa/pip/issues/4022). pip freeze | grep -v "pkg-resources" > requirements.txt
If you want to install the latest development version and/or need to change Lab itself, you can clone the Lab repo and install it in the virtual environment:
git clone https://github.com/aibasel/lab.git /path/to/lab pip install --editable /path/to/lab
The --editable
flag installs the project in "editable mode", which
makes any changes under /path/to/lab
appear immediately in the
installed package.
Please note that before running an experiment script you need to activate the virtual environment with:
source .venv/bin/activate
We recommend clearing the PYTHONPATH
variable before activating the
virtual environment.
