hls_model.build() cannot not work in Jupyter about hls4ml HOT 4 CLOSED

@jsncepu May I ask which HLS backend are you using? I would suggest checking the path for that HLS backend

I use vivado 2020.1 as backend. I can complete build process for part1 and part2 tutorials by inputing the command for example "hls4ml build -p model_1/hls4ml/prj" in the terminal. The project can be successfully built and report the csim, cosim and synth results. However, for part4 and part7a, the command doesn't work and remind me that configuration file is not found. It's weird enough.

import os
os.environ['PATH']+= os.pathsep + '/opt/Xilinx/Vivado/2020.1/bin'

@jsncepu Can you try this snippet in your ipynb file, changing the path according to your vivado path? If it doesn't work, please print the value of os.environ['PATH'] here.
I hope this helps.
Thank you.

Hi, I can build successfully by inputing the command vivado_hls build -f build_prj.tcl "csim=1 synth=1 cosim=1 vsynth=1" first and inputing the command vivado -stack 2000 -mode batch -source design.tcl to obtain the bitstream and hwh files etc. But I still cannot build the model from jupyter directly. But now, it doesn't matter for me.
