GVSTream object is not callable

[pechavarri]

Describe the bug
I am trying to capture with profiler but when doing "stream.pop_buffer ()" Stream says: "GVSTream object is not callable"

Here is the code:
import sys
import gi
import numpy as np
import ctypes
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
from PIL import Image as im
import cv2
import time

gi.require_version('Aravis', '0.8')

from gi.repository import Aravis

Aravis.enable_interface ("Fake")

try:
if len(sys.argv) > 1:
camera = Aravis.Camera.new (sys.argv[1])
else:
camera = Aravis.Camera.new ('192.168.100.200')
except TypeError:
print ("No camera found")
exit ()

payload = camera.get_payload ()

[x,y,width,height] = camera.get_region ()

stream = camera.create_stream (None, None)

for i in range(0,1024):
stream.push_buffer (Aravis.Buffer.new_allocate (payload))

print ("Start acquisition")

camera.start_acquisition ()

filas=1024
array_intensity= np.empty((filas,2048))

print ("Acquisition")

for i in range(0,filas):
inicio=time.time()
image = stream.pop_buffer ()
data=image.get_part_data(1)
f=image.get_part_pixel_format(1)
if f==17825795:
#arr2=np.ctypeslib.as_array(ctypes.cast(data, ctypes.POINTER(ctypes.c_int16)),(width,)).copy()
array_intensity[i]=np.ctypeslib.as_array(ctypes.cast(data, ctypes.POINTER(ctypes.c_short)),(width,)).copy()
#min_i=np.amin(array_intensity)
#max_i=np.amax(array_intensity)

stream.push_buffer(image)			
#array_intensity=np.vstack((array_intensity,arr2)) 
fin=time.time()

tiempo=fin-inicio
print('fps:', 1/tiempo)

#array_intensity=np.delete(array_intensity,0,0)
print('array:',array_intensity)
image_2D=im.fromarray(array_intensity)
image_2D.show()

print ("Stop acquisition")

camera.stop_acquisition ()
