I have been experimenting with the best way to save a numpy array to file whilst using pypy (this means that I can't use the obvious <code>numpy.save</code>, <code>numpy.savetxt</code> etc as they are not supported). I've tried using the Pickle module (which works with pypy) but Pickle will only let me save lists of data. Although I can use <code>array.tolist()</code>, this gets complicated when moving away from a 1D numpy array. I know that the Struct module can be used to save and load numpy arrays but I have not idea how to approach the problem and there seems to be little information online. Any helpful tips/tutorials would be very useful!

1. COI'm confused. Why can you not use pickle with the Numpy arrays directly?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
