GPU Access Limited by CGroup

I think i have read the config file correctly but currently i am failing at importing the hook:

[root@hpc-batch14 cgroup]# qmgr
Max open servers: 49
Qmgr: c hook cgroup
Qmgr: import hook cgroup application/x-python default pbs_cgroups.PY
Qmgr: s hook cgroup event=exechost_periodic,exechost_startup,execjob_attach,execjob_begin,execjob_end,execjob_epilogue,execjob_launch
qmgr: Syntax error

Mir current Config looks like this:
