Description
One of my colleague found this issue when trying to run the part7a model.build() using the containers from the packages of the repo : https://github.com/orgs/fastmachinelearning/packages?repo_name=hls4ml-tutorial.
I was able to reproduce it with a brand new install of vivado 2020.1 in a jupyter/base-notebook image. And I think this can be resolved following the solution from the following post : https://support.xilinx.com/s/article/000034450?language=en_US.
To find the right path for libudev.so.1, I just ran : find / -name "libudev.so.1" 2>/dev/null. And I added the following line to the part7a notebook : os.environ['LD_PRELOAD'] = '/usr/lib/x86_64-linux-gnu/libudev.so.1'.
I tried it in my container with vivado 2020.1 and with another one running the hls4ml-0.8.0-vivado-2019.1 image and I do not get the realloc error anymore.
Also, I think there is a typo in the name of the vivado docker image that is refered in the README.md of the repo since there is no vivado2019.2 for hls4ml 0.8.0.
Cheers!
