uv is a tool for creating virtual environments (along with many other features !) that can be useful for working on Alliance Canada resources.
For example, to download uv and create a Python environment with datalad installed:
# download uv
curl -LsSf https://astral.sh/uv/install.sh | sh
# verify uv installation
uv -h
# create datalad venv
uv venv datalad --python=3.12
# activate datalad venv
source datalad/bin/activate
# install git-annex and datalad
uv pip install git-annex datalad
# verify datalad installation
datalad --help
# deactivate datalad venv
deactivateWe can then use this datalad environment to access existing datasets on the local RIA store.
We will use a reckless --ephemeral installation of the dataset such that we do not consume additional inodes, and our changes do not modify the original dataset.
As an example, to access the cneuromod.things.fmriprep dataset:
source datalad/bin/activate
# to install the cneuromod.things.fmriprep dataset from the Rorqual RIA store
datalad install --reckless 'ephemeral' ria+file://$HOME/links/projects/rrg-pbellec/ria-rorqual#~cneuromod.things.fmriprep
