I have no idea whether this is related with the GIL. Anyhow, you may work around this by running the blocking function in a separate thread, although I only tested this with Gtk backends. Here is a related post.

The recent version of the mpl have better support for this (blocking_input.py) and the code should be reimplemented. -JJ On Mon, Mar 9, 2009 at 4:32 PM, Jonathan Taylor <jonathan.tay...@utoronto.ca> wrote: > Yes I already use this, but I think the problem is that the other > toolkits need the GIL to update but raw_input() also grabs the GIL so > you cannot examine your plot in a pause (i.e. raw_input()).
