Jim,
Thanks for taking care of this. I'll just fix it on my end and wait for the eventual updates in the repository.

Mike, My last comment was related to gr-ettus (ettus_rfnoc_graph.block.yml), which I installed with gnuradio 3.8 / uhd 4.1. But I do see that gnuradio 3.10 has the exact same issue (as you found) in uhd_rfnoc_graph.block.yml: https://github.com/gnuradio/gnuradio/blob/maint-3.10/gr-uhd/grc/uhd_rfnoc_gr aph.block.yml <https://github.com/gnuradio/gnuradio/blob/maint-3.10/gr-uhd/grc/uhd_rfnoc_g raph.block.yml> <https://github.com/gnuradio/gnuradio/blob/maint-3.10/gr-uhd/grc/uhd_rfnoc_g raph.block.yml> gnuradio/uhd_rfnoc_graph.block.yml at maint-3.10 . gnuradio/gnuradio GNU Radio - the Free and Open Software Radio Ecosystem - gnuradio/uhd_rfnoc_graph.block.yml at maint-3.10 . gnuradio/gnuradio github.com So, it looks like we've run into the same issue in different implementations. I can post and issue on the gnuradio github page as well.

Hi all, This goes in the category of "Did anyone else need to do this?". I'm running Ubuntu 20.04.5 LTS with GNURadio 3.8 (Maint) and UHD 4.0. I recently upgraded UHD to 4.2. I ran into a gnuradio issue starting a "RFNoC" flow graph with a syntax error for an unmatched ')': Self.rfnoc_graph=ettus_rfnoc_graph_0 = ettus.rfnoc_graph(uhd.device_addr("addr=xxx,type-n3xx"))) I was able to manually edit the generated python code to remove one of the parentheses and see the code work. I then upgraded gnuradio to 3.10 which had the same issue. I then compared the "uhd_rfnoc_graph.block.yml" block files between UHD4.0 and 4.2. It's significantly different as 4.0 uses python .join to build the argument list and UHD 4.2 uses the python module "ast" to generate the argument list. But the final line on the 4.2 version had the syntax error of the extra ')': self.rfnoc_graph = ${id} = uhd.rfnoc_graph(uhd.device_addr("${graph_args}"))) I removed one ')' then reinstalled gnuradio (make install) from the build directory and everything seemed to work after that. So, it seems like it is a simple syntax error. But normally something like this (in my experience) indicates that I might have missed some configuration step somewhere and have yet to see the other errors. So, has anyone seen something like this? Thanks, Mike
