Hi Cinaed, Sorry but I am beginner in USRP. What is the file dummy.dat please ? I don't have front end hardware.
If I run fmtest.py I have no problem but my target is to generate my own python code with my flow graph. Thanks you very much for your help.

Try grep dummy.dat ./fm_rx.grc which will return file: dummy.dat or just open the file with GRC and replace file source with your front end hardware. But you can run gnuradio/share/gnuradio/examples/analog/fmtest.py without using the GRC. -- CInaed P.S. - please keep the discussion on the mailing list. Thank you.

The GRC file is a text file which you can attach to email. -- Cinaed On 3/17/21 12:12 AM, COURANT Frederique - Contractor wrote: Hello all, I would like to known if someone has ever had this error when you want to generate python code with gnuradio : Generate Error: 'catch_execptions' >>>Failure Traceback (most recent call last): File "/usr/local/lib/python3/dist-packages/gnuradio/grc/gui/Application.py", line 710, in _handle_action generator.write() File "/usr/local/lib/python3/dist-packages/gnuradio/grc/core/generator/top_block.py", line 83, in write for filename, data in self._build_python_code_from_template(): File "/usr/local/lib/python3/dist-packages/gnuradio/grc/core/generator/top_block.py" line 123, in _build_python_code_from_template 'catch_excetions':fg.get_option('catch_exceptions') File "/usr/local/lib/python3/dist-packages/gnuradio/grc/core/FlowGraph.py", line 181, in get_option Return self.options_block.params[key].get_evaluated() KeyError: 'catch_exceptions' The problem is present with my personal flow graph and examples available with gnuradio.
