Cannot run benchmark_rate

[BIXUT]

Hi,

I tried to run the benchmark_rate.cpp and benchmark_rate.py but cannot. Do you have any idea whether it is because the uhd installation or my system settings.

Thanks.

BIXUT,

the error indicates that uhd python support is not present in your python version. Looks like you are attempting to run the benmark_rate.py directly from source. How did you installer UHD?

If you installed UHD via linux package manager you would also need to install the package python3-uhd to install the UHD Python API into your system python version.

Hi,

I just follow the steps in https://kb.ettus.com/Building_and_Installing_the_USRP_Open-Source_Toolchain_(UHD_and_GNU_Radio)_on_L.... I think it is Building and installing UHD from source code. How can I install the package python3-uhd? Do I need to install the UHD again?

Hi BIXUT,

on linux the python API typically is included when you build from source. 

If you build into a custom prefix (not installed you custom build to /usr/local/) than you may also need to tell python where to find the python API.

export PYTHONPATH=$LOCALPREFIX/lib/python3.12/site-packages:$PYTHONPATH

I would also expect that you would run the benchmark_rate tool from your installation location, so either /usr/local/lib/uhd/examples/benchmark_rate or $LOCALPREFIX/lib/uhd/examples/benchmark_rate.
