Installation¶
Stable version¶
Installing the latest stable version is possible either using pip or conda.
Using pip¶
To install pyregion with pip from PyPI simply run:
pip install --no-deps pyregion
Note
The --no-deps
flag is optional, but highly recommended if you already
have Numpy installed, since otherwise pip will sometimes try to “help” you
by upgrading your Numpy installation, which may not always be desired.
Using conda¶
To install regions with Anaconda from the conda-forge channel on anaconda.org simply run:
conda install -c conda-forge pyregion
Testing installation¶
To check if your install is OK, run the tests:
python -c 'import pyregion; pyregion.test()'
Development version¶
Install the latest development version from https://github.com/astropy/pyregion :
git clone https://github.com/astropy/pyregion
cd pyregion
python setup.py install
python setup.py test
python setup.py build_docs
Dependencies¶
Python 2.7 and 3.4+ are supported.
pyregion
has the following required dependencies:
- Astropy version 1.0 or later (which requires Numpy)
pyregion
has the following optional dependencies for plotting:
If you are using Astropy version 1.3 or later,
then you have astropy.visualization.wcsaxes
.
For older versions of Astropy, you have to install the separate package:
wcsaxes
To work with the development version, you’ll need Cython and a C compiler, because the code to generate masks from regions is written in Cython.
