Commonroad_rl:cannot import name 'LOG' from 'shapely'

CommonRoad-RL

Hi:
currently i’m using commonraod_rl to transfer xml to pickle.
But when the it runs, the system at my side report that:

ImportError: cannot import name ‘LOG’ from ‘shapely’

the shapely version in my computer is 2.0.6
The commonroad-drivability-checker version is released as 2024.1

I check the commonroad_rl code in git as below:

line 19 still have the code:
from shapely.geos import LOG

But there is no LOG in shapely.geos

So, is there any solution for this issue, or what should i do to fix this issue?

Hi Chris_Yin,

simply downgrading your shapely version should fix the problem.
Try pip install shapely<2.0.0. For me 1.8.0 works.

Hi Philipp:
i will try.
And i think I tried shapely 1.8.4 yesterday,but there’s a warning,says the commonroad-io may not work with this version.

I will try again today and post process.

Thank you

Another question is: why the latest version of commonroad_rl still these old version of shapely?

Hi:

when down grade shapely to 1.8.4, i have the following warning:

ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
commonroad-io 2023.1 requires shapely<3.0.0,>=2.0.1, but you have shapely 1.8.0 which is incompatible.

and i try to convert. it seems not work on my side.

Is it means i need to down grade commonroad-io as well?

Dear Chris,
we are working on an update, but for now that is your best approach, yes.
Best,
