Error when running on Jetson nano

[Lenni]

When I tried to run the benchmarking script on the Jetson Nano, I get the following Error:

I also get this error.

Hi! Could you please try adding --jetson_clocks to the command? For example:

sudo python3 benchmark.py --all --csv_file_path /benchmark_csv/tx2-nano-benchmarks.csv --model_dir /Desktop/benchmark/jetson_benchmarks/models/ --jetson_devkit nano --gpu_freq 921600000 --power_mode 0 --precision fp16 --jetson_clocks

Yep, it works by adding this flag.
