Installation¶
Attention
ShapePipe was not designed to be a stand-alone Python library. Instead users are expected to install the full ShapePipe environment on the system(s) where data should be processed.
Standard Installation¶
Tip
Check out Miniconda for a light weight and easy installation of Conda.
The standard installation of ShapePipe manages dependencies and scripts using a Conda environment. Therefore, to follow the standard installation Conda must be available on the system.
The ShapePipe package should first be cloned (or downloaded) from the GitHub repository.
Note
Developers should simply clone the repository as usual.
git clone -b <VERSION> --depth 1 git@github.com:CosmoStat/shapepipe.git
cd shapepipe
where <VERSION> is a
tagged release of ShapePipe
(e.g. v1.0.1). It is recommend to use the
latest release
unless you want to reproduce an older set of results.
Then, the entire ShapePipe environment, including dependencies, can be built
using the install_shapepipe script as follows.
./install_shapepipe
The install_shapepipe script will create the recommended Conda environment
along with all of the required core and module dependencies. The script also
provides a checklist for the success or failure of installing each of the
dependencies.
Once the installation is complete the shapepipe environment needs to be
activated.
conda activate shapepipe
A list installation options can be seen using the --help option.
./install_shapepipe --help
In particular, the --develop flag can be used to install additional tools
for developers.
MPI Installation¶
The standard installation of ShapePipe will install and enable MPI on a given
node (i.e. a given machine). However, mpi4py needs to be built from source
in order to take advantage of a preinstalled MPI distribution on the compute
nodes of a cluster.
This can be done as follows
./install_shapepipe --mpi-root=<PATH TO MPI>
where <PATH TO MPI> is the full path to MPI root directory (i.e. where the
bib, include and lib directories can be found). If the installation is
successful, ShapePipe will be able to submit jobs to all of the nodes in the
cluster.
Uninstalling ShapePipe¶
The --uninstall flag can be passed to install_shapepipe to remove the
entire ShapePipe environment.
./install_shapepipe --uninstall
Installing the ShapePipe Library Only¶
The ShapePipe library, i.e. the core package not including module dependencies, can be installed in the following ways.
After cloning the repository.
Warning
Note, this method will not include any system executables or examples.
pip install .
Without cloning the repository.
pip install git+https://github.com/CosmoStat/shapepipe.git
