Re: [sumo-user] libsumo DLL load error
|
Hi,
we regularly experience difficulties in using anaconda because it brings
its own libraries. Can you retry with a pure python?
Best regards,
Michael

Dear all,
I'm going to run sumo using libsumo and Python multiprocessing packages.
I successfully installed it using pip install libsumo.
However, importing libsumo from python results in the error message
"Module not found."
My error message is as follows
---------------------------------------------------------------------------ImportErrorTraceback (most recent call last) Cell In[1], line 97fromtqdmimporttqdm 8frommultiprocessingimportProcess, Pool ----> 9importlibsumoFile C:\Program Files (x86)\Eclipse\Sumo\tools\libsumo\__init__.py:3028fromtraciimportconnection, constants, exceptions, _vehicle, _person, _trafficlight, _simulation # noqa29fromtraci.stepimportStepManager, StepListener # noqa---> 30from.libsumoimportvehicle, simulation, person, trafficlight # noqa31from.libsumoimportTraCIStage, TraCINextStopData, TraCIReservation, TraCILogic, TraCIPhase, TraCIException # noqa32from.libsumoimportTraCICollision, TraCISignalConstraint # noqaFile C:\Program Files (x86)\Eclipse\Sumo\tools\libsumo\libsumo.py:1311# Import the low-level C/C++ module12if__package__ or"."in__name__: ---> 13from.import_libsumo 14else: 15import_libsumoImportError: DLL load failed while importing _libsumo: Module not found.
My environment is sumo 1.17, libsumo 1.17, and I use python 3.10.9 in
anaconda3.
I added site-package, sumo tools, sumo bin, etc. from anaconda env to
the path in the Windows system environment variable, but I still get DLL
load error.
How should I solve this problem?
Thank you so much for your kind response and good insights all the time.
