OSError: firmware/myproject-73DAB14B.so: cannot open shared object file: No such file or directory

I'm rewriting the ONNX converter and got the conversion to work. However, when I try compiling the hls model,I got this error:

I suspect that this is because I'm working on a fresh conda environment that I created on correlator2, so some libraries might not be set up appropriately ...

Never mind, it's just an error caused by not processing the layer's class name appropriately.

How did you address the error though?

[thesps]

Generally, this error means that the compilation of the C++ failed, so the shared library doesn't exist. You could try running the model 'build' to see the exact error in the Vivado log files.

Yeah. there is a build error with no matches for operator "=". Seems to be an issue with the way concat was implemented and how it works with conv layers
