Cannot Import "process_scenario" while executing batch_processing

CommonRoad-Search
1

Hello, I am having trouble executing batch_processing_parallel and batch_processing_sequential files, as I am always getting this Error:

Additionaly I have noticed, that many imports dont work, though I have not changed anything in the files. I marked the commonroad-search folder as source root, but this has not helped.
If I try to run the script from the tutorial_batch_processing in the python console, I get the same Import Error, but this time “cannot import name run_parallel_processing”
Any ideas what i might be doing wrong? Thanks very much in advance

Hello Vladislav,

Did you try to execute these scripts in the browser Jupyter notebook?

Thanks for your reply! Yes, unfortunately, I get an import error in Jupyter as well. I tried many things and I dont see a reason, why it shouldnt be possible to import the files

Hi Vladislav,

which installation option did you choose? And on which Platform are you running the Code?

Best,
Gerald

CommonRoad-Search requires python 3.7 (not a higher version). One reason for this error could be that your anaconda environment uses some other python version.

Hi Gerald,
I am using the VM installation option, running on virtual box. I ran the code on pycharm and tried in the browser using Jypiter Notebook, but result was the same.

Unfortunately, this is not the case, as I am using the VM with python 3.7.11

This is quite a strange situation, I just tried tutorial4(batch_processing) again in the vm environment. But I didn’t encounter the issue about unable to import process_scenario. Maybe you can uplode your changed student.py file to cloud and delete the VM file then re-unzip the VM image.

This has helped, thank you!
