Hello! Seems like something is using the video memory on my Jetson Nano and I can’t figure out what.
Since there is no nvidia-smi on Jetson Nano, I check video memory using Tensorflow. When tf.Session is initialized it logs:
2019-09-03 04:21:19.118556: I tensorflow/compiler/xla/service/service.cc:168] StreamExecutor device (0): NVIDIA Tegra X1, Compute Capability 5.3 2019-09-03 04:21:19.118912: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1433] Found device 0 with properties: name: NVIDIA Tegra X1 major: 5 minor: 3 memoryClockRate(GHz): 0.9216 pciBusID: 0000:00:00.0 totalMemory: 3.86GiB freeMemory: 2.86GiB
This is pure system after reboot with disabled GUI https://devtalk.nvidia.com/default/topic/1050739/how-to-boot-jetson-nano-in-text-mode-/
I tried to reboot, switch xorg off in case it took the memory, nothing helps.
I tried https://github.com/rbonghi/jetson_stats/wiki/jtop to monitor GPU usage but it doesn’t show the memory
Can you please say what might be the problem, or suggest a program which allows to view what processes use GPU
