This warns you that part of your Python infrastructure
(the content of "/home/conrado/.python-eggs") could be changed
by other people (than you).
You might not be concerned at all (if you act in a safe, trustfull
environment). Otherwise, you have essentially two options:
* prevent write access for others than you to "/home/conrado/.python-eggs"
(--> "chmod" command)
* move the part of your Python infrastructure to another
location not writable by "other" and "group" -
and tell your Python system where to find is (via
"set_extraction_path" or envvar "PYTHON_EGG_CACHE").

A "FutureWarning" warns about something that may give an error
in the future.
>From this specific message, I guess (!), that "_edgecolors"
consists in fact not of a single but of multiple components -
but is compared here to a single value. The warning means, that
the current behaviour (returning a scalar value) is likely to change
in the future (returning a composite value for the elementwise
comparison). Should this happen, the code will likely fail.
This warning comes from "matplotlib" - i.e. it is outside of
your immediate control. You can hope that a future version
of "matplotlib" will correctly handle the changed behaviour in the future --
and ignore the problem until then.
