ros wrapper issue "[detect_grasps-1] process has died ..."

[miladmalekzadeh]

Hi, I was able to run gpd without ros using eigen_params.cfg and krylon point cloud. Then I tried the gpd_ros. The installation went ok except some warnings regarding the libpcl version. I guess it is related to having version 1.7 in ros and 1.9 for gpd itself. I used ros_eigen_params.cfg file for ros with the realsense camera publishing pointcloud, but I see the following error:

Getting this same error. I tried running the lenet Eigen framework:

Excuse me, I have the same issue. Is there any solution? Thanks.

@miladmalekzadeh were you able to solve this ?

[jediofgever]

interesting ... in ros_vino_params.cfg, when I set weights_file to a directory it starts to work.

I change weights_file as;

weights_file = /home/atas/gpd/models/lenet/15channels/params/

@jediofgever If you want to use the customary neural network implementation based on Eigen, then weights_file should be the path to a directory with weight files (like here). If you want to use OpenVINO, then weights_file should be the path to the bin file with the weights (like here).
