[Qgis-user] Using the qplanet plugin on Windows? - pysqlite2, scipy

[Alister Hood]

OK,
The latest version of scipy didn't work because the osgeo numpy is too old.  I went right back to 0.6.0 and now I can import scipy successfully.  All I had to do was open the installer with 7-zip and copy the scipy folder into my site-packages folder.
I then had to make the same `import sqlite3` edit to $HOME/.qgis/python/plugins\Qplanet\planetsasha.py
It then failed at:

  File "C:/Documents and Settings/alister.hood/.qgis/python/plugins\Qplanet\gps.py", line 11, in 
    NaN = float('nan')
ValueError: invalid literal for float(): nan

This seems to be a problem on Windows:
http://bytes.com/topic/python/answers/803393-numpy-handling-float-nan-different-xp-vs-linux
I replaced the offending line in gps.py with the following code and now the plugin loads:

from numpy import nan
NaN = nan

Since I don't know how to use the plugin I'll need to come back some other time to see if it actually works :) (I thought I saw some instructions, but I don't know where).
I notice I get an error message if I click Plugins>Planet Sasha>Planet Sasha, but I'm guessing this could just a minor bug - that it doesn't check whether I've set up the preferences or something.

It is installed.  It just doesn't seem to contain pysqlite2

Ah, I tried that, but I think I just didn't go far enough.  When I tried opening the .exe inside the .exe it ran it instead.  But if I extract the .exe inside the .exe then I can open it... I'll try again.

Thanks.
