Getting Started example errors during execution

[tianrui-wei]

I was trying to run the getting started example in this repository, and here is the error backtrace I got

I was wondering if anyone would be able to take a look at this. Thanks!

What specific model were you trying to convert? And did you encounter the error when running this line?

hls_model = hls4ml.converters.keras_to_hls(config)

[tianrui-wei]

I was using the model from the example

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('KERAS_3layer.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()

and the errors indeed happened during that line

Hello,

I'am getting the same error. It's coming from this line hls4ml.converters.keras_to_hls(config). Did you manage to solve the problem?

Thanks :)
