any solution??

We tested our framework under Ubuntu 18.04 or 20.04. Apparently, you are running it under Windows, which expects a different path format. The important part of the abovementioned error is:

File "C:\Users*\anaconda3\envs\lidar\lib\multiprocessing\spawn.py", line 105, in spawn_main
trainer = Trainer(ARCH, DATA, FLAGS.dataset, FLAGS.log, FLAGS.pretrained)
File "../..\tasks\semantic\modules\trainer.py", line 69, in init
exitcode = _main(fd)
File "C:\Users*\anaconda3\envs\lidar\lib\multiprocessing\spawn.py", line 115, in _main
shuffle_train=True)
File "../..//tasks/semantic/dataset/kitti/parser.py", line 272, in init
self = reduction.pickle.load(from_parent)
ModuleNotFoundError: No module named 'parserModule'

I fixed this error by using os.path.join to account for the difference between ../..//tasks/semantic/dataset/kitti/parser.py, which is a valid path under unix-based operating systems, and ..\..\tasks\semantic\dataset\kitti\parser.py, which is a valid path under windows. Let us know if this fix resolves your issue.

aaaaaaa

the path is fine as you can see but the problem is still there?

I am getting this error?

It's hard for me to diagnose the problem as I haven't a Windows environment setup. We run the code mainly under Ubuntu 20.04 or 18.04. Sorry that we cannot provide support for Windows.

urbansound8K commented 3 years ago

thanks

I was able to run the code on Ubuntu

do you have any idea how to measure the distance of detected objects? I mean how to display the distance of an object after the segmentation?
