AttributeError in livestock

[muc-martin]

I installed livestock and anaconda according to the following tutorial https://kongsgaard.eu/install-livestock.html. However, I cannot get the example files to work as I get the following error.

from livestock.hydrology import run_model
File "H:\Anaconda\envs\livestock_env\lib\site-packages\livestock\hydrology.py", line 22, in
from livestock import geometry as lg
File "H:\Anaconda\envs\livestock_env\lib\site-packages\livestock\geometry.py", line 261, in
-> shapefile._Shape:
AttributeError: module 'shapefile' has no attribute '_Shape'

Could the error be possibly due to pyshp being version 2.x instead 1.x?
After downgrading pyshp to 1.2.12 I get following error:

File "H:\Anaconda\envs\livestock_env\lib\site-packages\livestock\hydrology.py", line 606, in run_model
project, mesh_info = mesh_to_cells(project, mesh_paths)
File "H:\Anaconda\envs\livestock_env\lib\site-packages\livestock\hydrology.py", line 55, in mesh_to_cells

c = project.NewCell(*center, area=polygon.area, with_surfacewater=with_surfacewater)
RuntimeError: Can't create cell #0. Area<=0.0

Hi @HerrHansDampf
I haven't used Livestock since sometime in 2018. So it is very likely that the dependencies are not working.

Hi @ocni-dtu ,
do you by any chance still have the conda environment you worked with, so I can reproduce it?
Attached is my cmf folder as well as the debug info
cmf.zip
livestock_debug.log

Traceback.log

[ocni-dtu]

@Martin-TUM it says in the traceback that the area of the cell is less than 0. Can you check that your geometry is correct?

[ocni-dtu]

I unfortunately doesn't have the environment anymore.
Try to use a version of CMF before 1.2. It looks like they changed how the handled geotry in 1.2: https://github.com/philippkraft/cmf/releases

I checked the geometry and it is a valid .obj file with all geometry included. Downgrading CMF to 1.1.1 (or lower) results in the following error:
