PyFerret is available pre-built as gzipped tar files for each of the systems listed below. The source code for PyFerret is also available as a gzipped tar file. See Installing or Building PyFerret for information on installing or building PyFerret from these files. At this time PyFerret cannot be built to run directly on Windows. See this WINDOWS_README file for more information on using a Linux version of PyFerret in a Linux virtual machine running under Windows.
The PyFerret 7.3 release, which encapsulates version 7.3 of Ferret, includes binaries for:
- RedHat Enterprise Linux 6 (RHEL6), 64-bit, which uses Python 2.6
- RedHat Enterprise Linux 7 (RHEL7), 64-bit, which uses Python 2.7
The latest PyFerret release for the Mac is is v7.0.
- Mac OS X 10.11 (El Capitan), using Python 2.7 - check the PyFerret GitHub site: https://github.com/NOAA-PMEL/PyFerret/releases
For many of the "free" Linux operating systems, the RHEL6 or RHEL7 versions (depending on whether it uses Python 2.6 or Python 2.7) should work. These binaries are (statically) linked with NetCDF-220.127.116.11 and HDF5-1.8.18 libraries, with OPeNDAP dataset access enabled.
For installing PyFerret using the pre-built files, download the appropriate PyFerret binaries tarball from the GitHub link. Starting with version 7.0.0, for PyFerret the environment files are part of the binaries tarball.
Ferret Datasets The datasets used for creating land outlines and masks, and also used by example and tutorial scripts. For Ferret v7.1, the datasets that are used by "go land" and "go land_detail" to draw land boundaries, national borders, rivers, and so forth on maps were updated.
For building PyFerret from source code, you only need to download the PyFerret source tarball from the NOAA-PMEL PyFerret GitHub repository.
