No module named 'commonroad_dc.pycrcc'

[you_bear_er_lai]

Hi all,

Because the virtual machine is too lagging, I want to install the program on the macOS, but I encountered such a problem. I followed https://commonroad.in.tum.de/docs/commonroad-drivability-checker/sphinx/installation.html#full-installation-with-anaconda for manual installation. The installation of the necessary third-party library has been implemented, but I encountered a problem when Compile the CommonRoad Drivability Checker library by running (after running $ sed -i ‘’ ‘s!-lccd!/usr/local/lib/libccd.2.0.dylib! and $ make)’ python_binding/CMakeFiles/pycrcc.dir/link.txt). I don’t know if it is because of this reason that the final problem is still not solved.

Hi, I can report this to my colleagues who have written the installation manual for the drivability checker. In the meantime, maybe you can try out docker for running the exercise?

Hi Edmond, thanks for your reply, i will.

Hi you_bear_er_lai,

Please add -DENABLE_SERIALIZER=0 after cmake
Or just remove libs11n.dylib from the path in the screenshot (with same effect).

Compilation with serializer is known not to work out-of-the-box under MacOSX. It is not needed for the exercise.

P.S. It could be installed with serializer support (pickle) under MacOSX, but the manual installation of gcc instead of using the integrated C++ compiler would be required.

Hi vitalii_rusinov,

Thanks for your suggestion, this error is finally resolved, but the problem “No model named CommonRoad_dc.pycrcc” still exists. I am running well with docker, if you have any other methods to solve this problem please let me know.

Hi,

Have you run python setup.py install in the end? (with the conda environment being activated) Could you possibly check if the pycrcc.cpython-37m-darwin.so is indeed in commonroad_dc folder of the git repository?

The only thing that we need is to copy this file into the site-packages/…/commonroad_dc/ folder (shown in the screenshot in your first message in green letters). It is usually achieved by running the python setup.py install

[you_bear_er_lai]

Hi,

yes, i did it, but it says there is no *.so file and the installation was not successful in the end, ich checked the pycrcc.cpython-37m-darwin.so is already indeed in commonroad_dc folder.

[vitalii_rusinov]

Hi,

You should remove the directory commonroad_drivability_checker… from the site-packages folder of the anaconda environment.

Then you should run

sudo python setup.py install

because it looks like you don’t have rights to write into your anaconda environment directory

It looks like compilation has succeeded, there are just not enough rights to write into the anaconda environment directory.

P.S. This advice is specific yo your situation, normally sudo is not required before running python setup.py install.

Thank you so much, the problem is solved! X)
