Hi Cédric, I have uninstalled the binary version of GNU Radio and replaced it with version 3.9.0.0, which I built from source as per the instructions on the following web pages:
- https://wiki.gnuradio.org/index.php/InstallingGR#From_Source - https://wiki.gnuradio.org/index.php/ModuleNotFoundError#B._Finding_the_Python_library I have verified the installation as follows: - $ gnuradio-config-info --version --> returns '3.9.0.0' - $ gnuradio-config-info --prefix --> returns '/usr/local' - $ find /usr/local -name gnuradio | grep "packages" --> returns '/usr/local/lib/python3/dist-packages/gnuradio' and '/usr/local/lib/python2.7/dist-packages/gnuradio' - Python3 interpreter: from gnuradio import uhd --> uhd.__file__ --> returns '/usr/local/lib/python3/dist-packages/gnuradio/uhd/__init__.py' - Reinstalled GNU Radio Companion via Ubuntu Software & Updates utility Next, I opened GNU Radio Companion and tried to connect to a UHD source like before. Result: Exactly the same problem as before! GRC is still pulling in UHD 3.10, even though I did not install that version of UHD: linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown UHD Warning: EnvironmentError: IOError: Could not find path for image: usrp_b200_fw.hex Using images directory: <no images directory located> Set the environment variable 'UHD_IMAGES_DIR' appropriately or follow the below instructions to download the images package.
