after changing factory.pyx

215             cdef str image_format = str(self.properties['PixelFormat'])
216             cdef str bits_per_pixel_prop = str(self.properties['PixelSize'])

it worked

>>> for im in cam.grap_images(1): print im
[[187 175 181 ..., 255 255 255]
 [189 185 177 ..., 255 255 255]
