Hello Shmuma, any idea how i can resolve this error :

Traceback (most recent call last): File "./python", line 37, in proc_tracker.check(gpus, processes, active_users) File "/home/mysystem/.config/python/gpu_mon/proc.py", line 128, in check proc_conf = self.conf.process_config(gpu_id) File "/home/mysystem/.config/python/gpu_mon/config.py", line 124, in process_config if gpu_id in c.gpu_indices: TypeError: argument of type 'NoneType' is not iterable

? Thank you
