Hi Rob,
Thank you for your reply. Yes I actually installed all the dependencies. The python path environment variable shows: echo $PYTHONPATH usr/local/lib/python2.7/site-packages:/usr/local/lib/python3/dist-packages: I have checked the locations but obviously the imagbuilder module is not found in those locations, but it is found in ~/rfnoc_devel/uhd/host/python/uhd/imgbuilder. I guess that the image_builder.py is not properly compiled... or is it sufficient to use this python script? I checked the CMake files but there was no link to the imgbuilder folder or the related python files... Could it be that there is no linkage to this script in the Cmake files? Do you use UHD-4.2 and are you able to run rfnoc_image_builder? No I do not specify the FPGA directories... Thank you again for your help!

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?

I checked the files for UHD4.0 (the rfnoc_image_builder runs fine here) but I am not experienced enough to find the problem... Any help would be very appreciated!

When I try to run rfnoc_image_builder, I get the following error: rfnoc_image_builder --help Traceback (most recent call last): File "/usr/local/bin/rfnoc_image_builder", line 29, in <module> from uhd.imgbuilder import image_builder ImportError: cannot import name 'image_builder' from 'uhd.imgbuilder' (unknown location) What is the issue here? I tried UHD4.1 but got the same issue here... Any help is very appreciated! BR, Anton
