Installation error

[mnishikawara]

I followed the installation guide by typing the following at the conda prompt: (conda install -c conda-forge porespy)
https://porespy.org/installation.html
After typing the script, the following error happened. The screenshot is attached.

How can I solne the problem?

Not totally sure what is causing your problem, but seems like you have too many packages in your environment and they are starting to conflict with each other. I suggest you make a new fresh env and install python.

HOWEVER, be sure to use python <3.13 since llvmlite does not seem to work in 3.13 yet, and numba requires it. I"m sure they'll get this sorted out soon, but as of yesterday I needed to use python 3.12.5.

Thank you.
By the way, What is the relationship between porespy and openpnm?
I had the installation problem for openpnm, but it was solved.
PMEAL/OpenPNM#2941
If openpnm can cover porespy, I don't need to install porespy.

You need to open Spyder or VSCode, or perhaps use JupyterLab. Then you can write a file like:

import porespy as ps
import matplotlib.pyplot as plt
im = ps.generators.blobs(shape=[500, 500], porosity=0.6, blobiness=2)
plt.imshow(im)

Basically, the 'conda' prompt is for installing things, while the IDE (Spyder, Jupyter, etc) is where you run the code.

Thank you so much. I could run the example.
