Problems in the Evaluation and Submission of segmentation

[Shixiaomeng7]

Thanks for this excellent piece of work! I encountered "Warning: could not find environment variable "-x", mpirun was unable to find the specified executable file, and therefore did not launch the job. Warning: could not find environment variable "-x", mpirun was unable to find the specified executable file, and therefore did not launch the job. This error was first reported for process rank 0; it may have occurred for other processes as well", but I have already run the chmod +x evaluate.sh command, and I would like to know how to create a hyperlink to the semantickitti dataset if it is placed in a different location, and is hyperlink necessary?

Hi, thanks for your attention. You may check whether the mpirun is installed correctly according to the instructions. Because there are different versions of mpirun (like open mpi, intel mpi, mpich etc.), and they work in slightly different ways. And, the hyperlink can be created by ln -s stored/path/of/semantickitti data/semantickitti. Feel free to contact me if you have more questions.

Thank you for such a quick reply, I can now run . /evaluate.sh now, but it doesn't move when it loads to this location, and it doesn't report an error to exit, but it just stops, have you ever encountered this?

And I've already completed the training once, and it didn't stop moving while training.

Well, I've met this before and found several reasons may cause this. You can check: 1. whether the process get stuck in loading data (due to wrong data path); 2. whether the CUDA_VISIBLE_DEVICES is set correctly.
