Error executing end2end_example/cybersecurity

[TheAxelax]

When running the notebooks/end2end_example/cybersecurity example the jupyter notebook fails to execute the line build.build_dataflow_cfg(model_file, cfg_stitched_ip)

Execution stops with the following output:

Intermediate outputs will be generated in /tmp/finn_dev_alex
Final outputs will be generated in output_ipstitch_ooc_rtlsim
Build log is at output_ipstitch_ooc_rtlsim/build_dataflow.log

I am using FINN_XILINX_VERSION=2020.1, as suggested by the Getting-Started article.

@TheAxelax, Did you find any solution? I am facing the same problem.
Thanks!

Facing same error.

[gunertatar]

same error too. Anybody solved ?

Hello,
My guess is that vivado is failing to finish up with the IPs (would have to see the logs to be sure...). But, assuming that is the problem, it may being caused by this issue: https://support.xilinx.com/s/article/76960?language=en_US

So, if you haven't yet applied this patch yet, it may help.

(I'm just guessing here, since I remember getting a similar error earlier this year...)
