A problem from SVM Training with my own pcd data

[FransicsXu]

Just follow the wiki tutorial I use the methon A
Method A
Preparations:
Each point cloud file needs to be called obji.pcd where i goes from 0 to num_files
pcd_directory is the location of the directory plus the root name of the training files, e.g., /home/userA/data/obj.
Training:
$ rosrun agile_grasp train_svm num_files pcd_directory/obj svm_filename [plots_hands] [num_samples] [num_threads]

So I write the command in terminal as follows:
rosrun agile_grasp train_svm 100 /home/xkx/agile_grasp_ws/src/agile_grasp-master/data/obj svm_cube false 200 12

the pcd files directory is /home/xkx/agile_grasp_ws/src/agile_grasp-master/data
this is my pcd data and their names

However, I get some of the problem:
