For the latest updates, see the Changelog.

3/8/2015: Version 1.1.6 released. Minor bug fixes for regressions introduced in 1.1.5, including incorrect handling of UTC offsets in units string by date2num/num2date. Datetime instances returned by num2date are now time-zone naive, so python-dateutil is no longer required.

3/1/2015: Version 1.1.5 released. Significant improvements to netcdftime and num2date/date2num - accuracy is now between a millisecond and a microsecond depending on the time interval and calendar used. use_ncconfig=True is now the default in setup.py, so the utility nc-config is used to find the library and include file paths.

Quick Start

  • clone github repository, or get source tarball (or Windows binary installers) from PyPI.

  • make sure numpy and (required) and Cython (recommended) are installed and you have python 2.5 or newer.

  • make sure HDF5 and netcdf-4 are installed, and the nc-config utility is in your Unix PATH. If setup.cfg does not exist, copy setup.cfg.template to setup.cfg, and make sure the line with use_ncconfig=True is un-commented.

  • run python setup.py build, then python setup.py install (with sudo if necessary).

  • To run all the tests, execute cd test; python run_all.py.

See the online docs for more details.
