The file 'vivado_hls' does not exist anymore

[Gabriel-MarcoSilva]

Here’s the translation to English:

I was trying to use hls4ml, followed the instructions from the quick start, but I always got the following error when running build():

Vivado HLS installation not found. Make sure "vivado_hls" is on PATH.

I went to the directory where I installed Vivado (2024.2) and looked for vivado_hls, but that file no longer exists. I searched in forums and they mentioned that the functionality was moved to vitis_hls. How do I use hls4ml now? How do I configure it to recognize vitis_hls instead of vivado_hls?

I also tried copying the file and renaming it to use it, but I got the following error:

Project myproject_prj does not exist. Rerun "hls4ml build -p my-hls-test".

Use Vitis backend

Thanks!!! I've been trying for three weeks. And this was the most I could do.

Hey I wanted to ask what else did you do with this? I'm having the same problem. The Vivado I have is also 2024.1 and I'm using the pynq-zu fpga.

When I change the VivadoAccelerator backend into Vitis backend I get this message:
TypeError: VivadoBackend.create_initial_config() got an unexpected keyword argument 'board'

I was using the quick start example code, and it has the print(config) option, I saw it in the console and copied what was being configured and pasted it into the config variable, and there I changed the fields in this case I changed the board and the backend.

After that I did hls_model.compile(), followed by hls_model.build(), which generated a series of files, but I don't know what to do with them, when I put them in Vivado it simply crashes my laptop
