Still no solution but a few comments:
1) What you write here and on SE are not the same. Please cut-and-paste because details matter. For example, the SE code has "import matplotlib.pyplot" and then "plt.figure" but that code crashes because you did not import "as plt" like you do here...
2) It seems to be an echo issue. In my *with_matplotlib* buffer in Emacs, I see:
#+BEGIN_EXAMPLE

plt.savefig('myfig.png')
'myfig.png'
open('/var/folders/bl/trcxdptd1_q4k6q5fdhvp2m00000gn/T/babel-52565cmH/python-525659vF', 'w').write(str(_))

Where you see everything printed twice. I notice that in addition, you have
> r/folders/kz/1c2cxn1x60n_t5p2j1p02b180000gn/T/py6499_X0''', 'exec'));
at the top of your buffer, and I do not. I think the "exec" might be causing everything to echo as it runs, so everything is printed 2x, and that confuses Org, and it is not able to capture your filename.
-k.
