Installation of PyImfit¶
Note that since PyImfit is only meant to work with Python 3
(specifically, version 3.5 or later on Linux and version 3.6 or later on
macOS), I reference pip3
instead of just pip
in the example
installation commands below. If your version of pip
automatically
installs into Python 3, then you don’t need to explicitly specify
pip3
.
Standard Installation: macOS¶
A precompiled binary version (“wheel”) of PyImfit for macOS can be
installed from PyPI via pip
:
$ pip3 install pyimfit
PyImfit requires the following Python libraries/packages (which will
automatically be installed by pip
if they are not already present):
- Numpy
- Scipy
Astropy is also useful for reading in FITS files as numpy arrays (and is required by the unit tests).
Standard Installation: Linux¶
PyImfit can also be installed on Linux using pip
. Since this
involves building from source, you will need to have a working
C++-11-compatible compiler (e.g., GCC version 4.8.1 or later); this is
probably true for any reasonably modern Linux installation. (Note: a
64-bit Linux system is required.)
$ pip3 install pyimfit [or "pip3 install --user pyimfit", if installing for your own use]
If the installation fails with a message containing something like “fatal error: Python.h: No such file or directory”, then you may be missing headers files and static libraries for Python development; see this Stackexchange question for guidance on how to do that.
