Hello all,

I am doing a lgsvl simulator demo from here and getting this error when launching the my_map.launch file as shown below. C:\fakepath\Screenshot from 2020-04-04 16-53-10.png

Here is the error: ['roslaunch', '/home/autoware/shared_dir/autoware-data/BorregasAve/my_launch/my_map.launch'] pid=1399 sched policy=OTHER prio=0 [pcl::PCDReader::readHeader] No points to read load failed /home/autoware/shared_dir/autoware-data/BorregasAve/data/map/pointcloud_map/BorregasAve.pcd load /home/autoware/shared_dir/autoware-data/BorregasAve/data/map/pointcloud_map/BorregasAve.pcd I am running Autoware on docker 19.03 and nvidia-doker 2.2.2. And I am using './run.sh -t 1.12.0' to start the autoware docker.

Please help me if I am making a mistake anywhere.

Thanks!

You have to use git lfs: git lfs install before clone/pull the autoware-data repo. Did you?

Hi @pedroexe

I deleted my autoware-data folder and installed git-lfs by running sudo apt-get install git-lfs. I recloned the autoware-data on shared_dir folder and tried loading map lauch file again on Autoware. But it did not change anything. I am getting the same error.

 load failed /home/autoware/shared_dir/autowaredata/BorregasAve/data/map/pointcloud_map/BorregasAve.pcd

Somehow Autoware is not able to load the data from the above path. Please help.

Thank you!

Can you check the sizes of the files? They should be some MB (BorregasAve.pcd is 13MB in my computer).

@pedroexe I looked at the file size and it is only 132 bytes. This might be the problem. I will try to download manually.

Ok. That is probably the problem then. You have not only to install git-lfs (sudo apt), as you did, but also initialize it before cloning with git lfs install command. Sorry if my instructions were unclear. I just remind it from the top of my head. You can search on how to use git-lts in more detail, because that appears to be the problem.

I tired downloading the zip file from here and still getting the BorregasAve.pcd file size as 132 bytes. Any work arround? @pedroexe

Got you. Will try that and let you know.

I tried it and this time the downloaded file was 3.1 MB and not 13MB. I tried launching the map this time and the error 'No points to read' was gone. But still I am getting an other error as shown below. Please advise.
