got AttributeError: 'numpy.ndarray' object has no attribute 'clf' for 3d input

Hi,

I have got this error when dealing with 3d input data.

Traceback (most recent call last):

File "", line 4, in
iter_callback=visual_callback_3d)

File "/Users/renne/anaconda3/lib/python3.7/site-packages/morphsnakes.py", line 346, in morphological_chan_vese
iter_callback(u)

File "", line 37, in visual_callback_3d
fig.clf()

AttributeError: 'numpy.ndarray' object has no attribute 'clf'

Could you please help answer it?

Many thanks,

Renne
