Hi Anton,
Did you install all of the dependencies listed here
<https://files.ettus.com/manual/page_build_guide.html#build_dependencies_ubuntu>?
The error is a python error in not finding a needed package. It is possible
you need to configure PYTHONPATH to point to a UHD folder.  Did you specify
the FPGA_DIR option to rfnoc_image_builder?
