For Nvidia GPUs there is a tool nvidia-smi that can show memory usage, GPU utilization and temperature of GPU.
For Intel GPU's you can use the intel-gpu-tools.
AMD has two options
fglrx (closed source drivers):
aticonfig --odgc --odgtAnd for mesa (open source drivers), you can use RadeonTop
sudo apt install radeontop radeontop

After finding the process corresponding to your code in the bottom panel, by looking for your user ID (i.e., ONYEN) under the USER column, you can examine the GPU and GPU MEM columns to get the GPU utilization, GPU memory usage, and GPU memory utilization for your process. A nice feature of nvtop is that the output automatically updates. Here, I can see my process is using 39% of the GPU and 7% of the GPU's memory (i.e., 2680 MiB of GPU memory). After you have finished monitoring, be sure to exit the node by typing exit and hitting Enter. The atop command is a powerful UNIX command-line utility for monitoring system resources and performance.

To get real-time insight on used resources, do:
nvidia-smi -l 1
This will loop and call the view at every second.
If you do not want to keep past traces of the looped call in the console history, you can also do:
watch -n0.1 nvidia-smi
Where 0.1 is the time interval, in seconds.
