This repository is used to store the binder environment used to run the notebooks in https://docs.pymc.io/projects/examples/en/latest/ (hosted on this GitHub repo)
This freezes the dependencies at the time of each snapshot to ensure notebooks can always be executed on binder and accelerate loading the binder kernel for the notebooks.
To update the requirements.txt use
pip-compile requirements.in --resolver=backtracking -U
which will generate the new requirements.txt. You'll need pip-tools installed
