Tensorflow: Retraining inception v3 shows 0 % GPU usage -


i trying out tensorflow's inception model , while use gpu bottlenecks generation, doesn't seem on training-wise.

  • gpu usage monitored through nvidia-smi, stays @ 0%
  • log_device_placement returns gpu:0 80% of operation seems fine.
  • at beginning detect titan x usual /job:localhost/replica:0/task:0/gpu:0 -> device: 0, name: titan x (pascal), pci bus id: 0000:01:00.0
  • the memory on gpu allocated
  • cuda installed , cudnn both last version
  • the temperature rise (about 20 celsius 40->60) cpu heating whole case?

another way check whether gpu used nvprof. can tell sure.

for many models, check argument specify gpu count. example: num_gpus. few examples default not use gpu unless specified.
