Getting started

Requirements

simsopt requires python 3.x. For now, simsopt itself (as opposed to the separate physics modules like VMEC) is pure python, and so it does not have any mandatory requirements other than certain python packages, listed in requirements.txt. These packages are all installed automatically when you install using pip, as discussed below. If you prefer to install via python setup.py install, you will need to install these python packages manually using pip or another python package manager such as conda.

For requirements of separate physics modules like VMEC, see the documentation of the module you wish to use.

Installation

Installation from PyPI is not yet available, but it is planned soon.

First, clone the repository using

git clone https://github.com/hiddenSymmetries/simsopt.git

Then install the package to your local python environment with

cd simsopt
pip install -e .

The -e flag makes the installation "editable", meaning that the installed package is a pointer to your local repository rather than being a copy of the source files at the time of installation. Hence, edits to code in your local repository are immediately reflected in the package you can import.

If the installation is successful, simsopt will be added to your python environment. You should now be able to import the module from python:

>>> import simsopt

On some systems, you may not have permission to install packages to the default location. In this case, add the --user flag to pip so the package can be installed for your user only:

pip install --user -e .
