Solving error for random_spheres command

[Mah6iid]

Hello,

I am trying to use your example for generating a porous medium with spherical pores.

shape = [300, 300]
r = 15
im = ps.generators.random_spheres(shape=shape, r=r)
fig, ax = plt.subplots(1, 1, figsize=[4, 4])
ax.axis(False)
ax.imshow(im, origin='lower', interpolation='none');

However, I am getting an error in python: "random_spheres() got an unexpected keyword argument 'shape'". How should I solve this error?

Thanks,

The argument is im_or_shape, not just shape. You can specify a shape or you can pass an image that is already populated with some True values, and the function will insert spheres into the False regions. Docs are here

Thank you for your response. I created a structure using "overlapping-spheres" generator. However, I realized that this command creates images in which the spheres are not contained in the image and they touch or pass through the edges. I tried using some modifications, like "mode=contained", but this one does not work on "overlapping-spheres" command. Could you please guide me on how I achieve such a structure? Here is the code that I used for generating the structure.

"import porespy as ps
import numpy as np
import matplotlib.pyplot as plt

Generate structure

shape = [100, 100, 100]
e = 0.5
r = 10
mode = 'extended'

im = ps.generators.overlapping_spheres(shape=shape, r=r, porosity=e, edges=mode)
"

Thank you very much,

Hi @Mah6iid, please keep digging through the docs. There are examples for every generator that explain how each argument works. I think you are just using the wrong arguments with the wrong functions.
