The flag transpose in to_csv is nice but creates an extra axis with a default name (an integer).
Btw, users may want to change that meaningless default name.
So when you try to read the CSV file after, you get an LArray object with shape like
'axis1 (10) x axis2 (16) x axis3 (8) x default (1)' and then you need to reshape the array to get rid of this last axis.

Do you think it worth to do something about it?

+1 for an ability to change that name (and have some something more sensible as default, like "value")
+1 for being able to read that back nicely, though I don't know how to improve on the current situation. Please provide mockup syntaxes and (tiny) output examples.
Btw: In this situation, I have so far told our users to use ['label_of_default_axis'] to get rid of it. It is simpler than reshape.

@gdementen rename argument transpose as vertical or data_to_column?

I have never heard it called "vertical".

  • Wikipedia speaks about wide and narrow (sometimes un-stacked and stacked, or wide and tall)
  • Pandas uses wide and long

From a quick google search, the most common of the terms above seems to be "wide". So use wide=True instead?

OK for wide. We need to add some explanation/examples in the tutorial ;)
