  • Owner changed from someone to ole

SVN Branch Created and migration started.

Problem: Scientific.IO.NetCDF does not yet work with numpy. See ​http://starship.python.net/~hinsen/ScientificPython

This has been looked into . Numpy was good. Netcdf is not supported though, so we will stick with Numeric

comment:3 Changed 18 years ago by ole

It seems that NetCDF is now supported:

See ​http://netcdf4-python.googlecode.com/svn/trunk/docs/netCDF4-module.html or ​http://code.google.com/p/netcdf4-python/ or ​http://pydap.org/plugins/netcdf.html

This may also solve the 2GB limitation mentioned in ticket:35

Numpy can be downloaded at ​http://www.numpy.org/

  • Keywords numpy migration added
  • Owner changed from ole to rwilson
  • Priority changed from lowest to highest

Initial work towards migration to Numpy was done in changeset:2544 through to changeset:2548 as well as changeset:3749. It wasn't too hard but the NetCDF issue stopped the progress at the time. Now, two years later, we are pretty optimistic that it'll work.
