Error while reading NAM file

[afernandezody]

I'm trying to read a NAM file with the code:

import xarray as xr
import numpy as np

file_path = '/home/ubuntu/DATA/nam20250105.t00z.awphys00.tm00.grib2'
# Open the GRIB2 file using the cfgrib engine
try:
    ds = xr.open_dataset(file_path, engine='cfgrib')

    # Print the dataset to see all dimensions, coordinates, and attributes
    print(ds)

    # Access specific properties/attributes
    # Example: Global attributes
    print(f"\nGlobal attributes: {ds.attrs}")
    print(f"File history: {ds.attrs.get('history')}")

    # Access specific variables and their attributes
    # The variable name will depend on your GRIB file content (e.g., 't2m' for 2m temperature)
    # You can see variable names in the print(ds) output
    variable_name = 't2m' # Example variable name
    if variable_name in ds.variables:
        print(f"\nProperties of variable '{variable_name}': {ds[variable_name].attrs}")
        print(f"Units of {variable_name}: {ds[variable_name].attrs.get('units')}")
        print(f"Long name of {variable_name}: {ds[variable_name].attrs.get('long_name')}")

        # Access coordinates (lat/lon)
        lats = ds[variable_name].latitude.values
        lons = ds[variable_name].longitude.values
        print(f"\nLatitude range: {np.min(lats)} to {np.max(lats)}")
        print(f"Longitude range: {np.min(lons)} to {np.max(lons)}")

except Exception as e:
    print(f"Error reading GRIB file: {e}")

However, it returns the error:

Error reading GRIB file: multiple values for unique key, try re-open the file with one of:

Any suggestion on what I might be doing wrong. Thanks.
