Error running simple mechanism reduction case

[Zyr1ak]

Hello,

I have started using cantera and pymars for a couple of days so it is still a code i am unfamiliar with. For a project, i need to reduce some complex mechanism for biomass pyrolysis using CRECK database. While i ran the chemical mechanism reduction command for the simple tutorial case available on the website : pymars --input reduction_input.yaml using the same procedure as the website I see the following error:
Traceback (most recent call last):
File "/home/adil/anaconda3/bin/pymars", line 8, in
from pymars.main import main
File "/home/adil/anaconda3/lib/python3.12/site-packages/pymars/main.py", line 4, in
from .pymars import pymars
File "/home/adil/anaconda3/lib/python3.12/site-packages/pymars/pymars.py", line 19, in
from .tools import convert
File "/home/adil/anaconda3/lib/python3.12/site-packages/pymars/tools.py", line 9, in
from cantera import ck2cti
ImportError: dynamic module does not define module export function (PyInit_ck2cti).

The mistake probably might be silly and come from me. I thought that it might come from installation or python version but didn't work out. I am too unfamiliar with the code to look into it in detail either. (tried unsucessfully).

Please kindly help.

Hello, I have encountered the same problem as you. Have you solved it? How did you solve it? Thank you very much.

Hello, yes I managed to solve it somehow. I created two different environments, one running python 9.6 to use pymars module options and one using python 9.12 to use pure cantera problems. Using that I managed to make the cases work. Best regards, Adil
