Re: Why is a range in relax created as xrange objects which is not sliceable? -- December 10, 2013 - 14:14

Hi Edward.

To solve the wxPython problem on my Mac 10.9, I reverted

to use "epd" enthought python distribution.

This ships with dateutil version 1.5, which give the problem.

I have written the install details here:

http://wiki.nmr-relax.com/Installation_mac_mavericks_os_x

The fix for dateutil was dead simple.

sudo pip install python-dateutil --upgrade

I have noted this down here:

http://wiki.nmr-relax.com/Matplotlib_dateutil_bug

Now I am finally in position to plot directly in matplotlib.

Ok, so it was an some random package failing!  According to
http://labix.org/python-dateutil, version 2.0 is Python 3 compatible.
So these lines must have been fixed.  Matplotlib looks like it bundles
dateutil with itself.  I don't know how long it will take matplotlib
to bundle a functional dateutil package!  Are you using the newest
version of matplotlib?

Regards,

Edward
