qkeras_mnist_dense example fails to convert

Created by: siorpaes

I am trying the 'qkeras_mnist_dense' example using the following script derived from the Getting Started section:

import hls4ml

#Fetch a keras model from our example repository
#This will download our example model to your working directory and return an example configuration file
config = hls4ml.utils.fetch_example_model('qkeras_mnist_dense.json')

print(config) #You can print the configuration to see some default parameters

#Convert it to a hls project
hls_model = hls4ml.converters.keras_to_hls(config)

# Print full list of example models if you want to explore more
hls4ml.utils.fetch_example_list()

print(hls_model)

#Use Vivado HLS to synthesize the model
#This might take several minutes
hls_model.build()

#Print out the report if you want
hls4ml.report.read_vivado_report('my-hls-test')

The model is being downloaded but the process stops almost immediately with this error:

The Conda environment being used is the usual 'hls4ml-tutorial-0.5.0'
