Unable to generate bitfile

[CestMerNeil]

I am now trying to reproduce this tutorial, however I am unable to generate a bitfile and there is an error when I run the following code in part 7a

hls_model.build(csim=False, export=True, bitfile=True)

ERROR:

I am using Ubuntu and using the provided Docker image with Vivado.

Here is the log file:

I am sorry to say that this is a Vivado generated problem.

To solve this problem, I refer to the following URL of AMD.

In this project, I solved the problem by modifying the first block of code in notebook 7a as follows:

from tensorflow.keras.models import load_model
from qkeras.utils import _add_supported_quantized_objects

co = {}
_add_supported_quantized_objects(co)
import os

os.environ['PATH'] = os.environ['XILINX_VIVADO'] + '/bin:' + os.environ['PATH']
os.environ['LD_PRELOAD'] = '/lib/x86_64-linux-gnu/libudev.so.1'

Many thanks, you fixed my problem
