error when trying to run itzi.

[geoendemics]

Hi guys finally I got the time to try itzï.
I installed it using the source file
I am running Ubuntu 22.04.3 LTS and GRASS GIS 8.2.1. So far, I managed to install and run itzï according the tutorial.

I run the test as you suggested using the following commands and everything seems to be ok

itzi version
itzi run -h

When I try to run the simulation for surface modelling I get the following message:

(Wed Sep 6 00:15:02 2023)
itzi run ch_cuenca1
Starting simulation of ch_cuenca1...
WARNING: Error during execution: itzi.itzi_error.ItziFatal:
'[grass] section is missing.'
Simulation(s) complete. Elapsed times:
ch_cuenca1: 0:00:00
Total: 0:00:00
Average: 0:00:00
(Wed Sep 6 00:15:03 2023) Command finished (0 sec)

below my parameter file

[time]
duration = 02:00:00
record_step = 00:05:00

[input]
dem = Chile_19s_sirgas2021@PERMANENT
friction = n@PERMANENT
rain = rain@PERMANENT
bctype = bctype@PERMANENT
bcval = bcvalue@PERMANENT

[output]
prefix = nc_itzi_tutorial
values = h, wse, v, vdir, boundaries

[statistics]
stats_file = nc_itzi_tutorial.csv

I was looking into the documentation and seems to be that Itzĩ try to run outside the shell, which according to your documentation will require a grass section. But I am running ith from within .

I would appreciate any help I can get to solve this issue
best regards

Itzi has yet to be tested with grass 8, so this might be the issue.

thanks for your quick response. I installed grass 7.8.6 on ubuntu 18 lts. Installed itzi as explained in the tutorial still get following error:
itzi run -h

Itzi is only compatible with python 3. It is strange that it tries to run with python 2.
