Packages can be added to the Conda environment via two mechanisms either of which work fine.
Python has native Conda Environment support, hence from within a notebook using the Kernel simply calling Conda will install any package correctly to the current environment. This has the added advantage (if this is a python-based project), of capturing your package installs within a Notebook for ease of re-reproducibility for others.
The terminal can also be used to install any Conda packages using the following commands;
source activate /data/conda/<environment_name> conda install -y <package> # e.g # source activate /data/conda/myenv # conda install -y numpy |
