Error "Can't load geometry" and Warning "Missing geometry for traffic objects"

Question

Using SensCompute with a Windows host system may result in the following issues:

  • "Can't load geometry"
  • "Missing geometry for traffic objects"

In general, these issues describe a faulty circumstance where some required tools of CarMaker to utilize GPU sensors cannot access the project files. This may happen when a Windows host system is used, because Windows-based paths are wrongly sent to the Linux-based SensCompute system, e.g.:

  • Target: /CM_Projects/Test_Project
  • Actual: C:/CM_Projects/Test_Project

Solution

There is a workaround for this issue before a proper solution is implemented.

  1. Connect via passwordless ssh from the Windows host system to the target SensCompute system (e.g. using the user "developer": ssh developer@senscompXX)
  2. Verify the current working directory by executing command pwd. The correct outcome should return /home/developer
  3. Create a symbolic link in the home folder using the following command: ln -s / ./C:
  4. Change the current directory to the project folder. For example, cd /CM_Projects/Test_Project
  5. Create the same symbolic link in the project folder now: ln -s / ./C:
  6. Close the ssh session with the command exit.

Caution:

  • The symbolic link for the home folder must be set only once for every user on the SensCompute module. In case you change the user from e.g. "developer" to "expert", create the same symbolic link in the "expert" home folder.
  • If you use a project folder located on another Windows drive with e.g. the drive letter "D:", the symbolic link must be changed accordingly.
  • This symbolic link is required for every newly created project folder once.
