Need Help with oneAPI backend

[Boostedx]

I just wanted to ask on how I should write the python code for oneAPI back-end, it only produces a emulation file, what I want is a fpga hardware file so that I can synthesize it on my FPGA board.currently I have this:

`def convert_to_hls4ml(keras_model, x_test, y_test_cat=None, precision='ap_fixed<16, 6>', reuse_factor=4):    
    output_dir = '/home/renz/hlstest/oneAPItest4'
    os.makedirs(output_dir, exist_ok=True)

#Generate HLS4ML config with optimized settings
hls_config = hls4ml.utils.config_from_keras_model(
    keras_model, 
    granularity='name'
)

# Global Strategy for reduced resource usage
hls_config['Model']['Strategy'] = 'Resource'

# Ensure precision is a string
for layer in keras_model.layers:
    if isinstance(layer, Dense):
        hls_config['LayerName'][layer.name] = {
            'Precision': str(precision),  # Ensure precision is a string
            'ReuseFactor': reuse_factor,  
            'Strategy': 'Resource'
        }

# Convert Keras model to HLS4ML model with oneAPI backend
hls_model = hls4ml.converters.convert_from_keras_model(
    keras_model,
    io_type='io_stream',
    hls_config=hls_config,
    output_dir=output_dir, 
    backend='oneAPI', # Use oneAPI for conversion
    part='5CSEMA5F31C6'
)

hls_model.compile()  # Compile HLS model

return hls_model

The command to use, after compiling the model, is build, hls_model.build(build_type='fpga'). You can look at the options at:

https://fastmachinelearning.org/hls4ml/autodoc/hls4ml.backends.oneapi.html#hls4ml.backends.oneapi.oneapi_backend.OneAPIBackend.build

(This is not the function you call directly, but hls_model.build() calls the backend-specific function with the same arguments.) Note that the building is based on what is given in oneAPI-samples, so you can also manually work with the cmake file.

By the way, as an aside, it's also usually a good idea to pass backend='oneAPI' to the config_from_keras_model so that it also adds configurations for backend-specific optons.
