trouble with relative / absolute functions import in scikit-image

One ugly hack to resolve this would be to move that import inside the function, like

def hessian_filter(image, scale = (1, 10), scale_ratio = 2, beta1 = 0.5, beta2 = 15):
   ""
"
Blah - blah - blah ""
"
from..feature
import hessian_matrix, hessian_matrix_eigvals
#
function body

Histogram from which to determine the threshold, and optionally a corresponding array of bin center intensities. An alternative use of this function is to pass it only hist.,This function uses the Difference of Gaussians method for applying band-pass filters to multi-dimensional arrays. The input array is blurred with two Gaussian kernels of differing sigmas to produce two intermediate, filtered images. The more-blurred image is then subtracted from the less-blurred image. The final output image will therefore have had high-frequency components attenuated by the smaller-sigma Gaussian, and low frequency components will have been removed due to their presence in the more-blurred intermediate.,Standard deviation for Gaussian kernel. The standard deviations of the Gaussian filter are given for each axis as a sequence, or as a single number, in which case it is equal for all axes.,Histogram from which to determine the threshold, and optionally a corresponding array of bin center intensities. If no hist provided, this function will compute it from the image.

>>> image = np.array([1, 2, 3, 2, 1, 2, 1, 3, 2]) >>>
   apply_hysteresis_threshold(image, 1.5, 2.5).astype(int)
array([0, 1, 1, 1, 0, 0, 0, 1, 1])

>>> from skimage.data
import camera, astronaut
   >>>
   from skimage.filters
import butterworth
   >>>
   high_pass = butterworth(camera(), 0.07, True, 8) >>>
   low_pass = butterworth(astronaut(), 0.01, False, 4, channel_axis = -1)

>>> from skimage.data
import astronaut
   >>>
   from skimage.filters
import difference_of_gaussians
   >>>
   filtered_image = difference_of_gaussians(astronaut(), 2, 10,
      ...channel_axis = -1)

>>> filtered_image = difference_of_gaussians(astronaut(), 2,
   ...channel_axis = -1)

>>> from skimage.data
import camera
   >>>
   filtered_image = difference_of_gaussians(camera(), (2, 5), (3, 20))

>>> from skimage
import data
   >>>
   camera = data.camera() >>>
   from skimage
import filters
   >>>
   edges = filters.farid(camera)

Syntax of import statements :
User can import both packages and modules. (Note that importing a package essentially imports the package’s __init__.py file as a module.) User can also import specific objects from a package or module.
There are generally two types of import syntax. When you use the first one, you import the resource directly.

import gfg

When user uses the second syntax, then user import the resource from another package or module.

from gfg
import geek
