Re: [Matplotlib-users] Still a memory leak in matplotlib?

[Remo G. <su...@li...>]

Hi Föhn,

By default, the pyplot interface (recall that it is a Matlab-like state 
machine) does not release a figure's memory. You need to do this by hand 
by calling the clf() method after every plot you make:
...
plt.close()
plt.clf()

Stackoverflow contains a few threads about the subject.

Best,
Remo
