# Because it is surprisingly difficult to activate a conda environment inside a DockerFile
# (from personal experience and per https://github.com/ContinuumIO/docker-images/issues/89),
# we just update the base/root one from the 'environment.yml' file instead of creating a new one.

# Set up environment
RUN conda install -y mamba
RUN mamba env update -n base -f "$pandas_home/environment.yml"
