code: def load(cls, filename, gzipped, byteorder='big'):
          
          open_file = gzip.open if gzipped else open
          with open_file(filename, 'rb') as buff:

docs: Read, parse and return the file at the specified location.
  
          The `gzipped` argument is used to indicate if the specified
          file is gzipped. The `byteorder` argument lets you specify
          whether the file is big-endian or little-endian.
