vivado_hls missing

[DrBwts]

Ubuntu 24.04 Vivado 2024.1 (64 bit)

Ran,

conda env create -f environment.yml
conda activate hls4ml-tutorial

I'm trying to run the "Get started" notebook.

Its all fine until I run 2nd to last cell hls_model.build(csim=False)

Which throws the following error,

Exception                                 Traceback (most recent call last)

Which version of Vivado are you using?
