'Saves symbol to a file.
You can also use pickle to do the job if you only work on python.
The advantage of `load`/`save` functions is that the file contents are language agnostic.
This means the model saved by one language binding can be loaded by a different
language binding of `MXNet`.
You also get the benefit of being able to directly load/save from cloud storage(S3, HDFS).
Parameters
fname : str
The name of the file.
- "s3://my-bucket/path/my-s3-symbol"
- "hdfs://my-bucket/path/my-hdfs-symbol"
- "/path-to/my-local-symbol"

symbol.load : Used to load symbol from file.'

def save(self, fname):

    if (not isinstance(fname, string_types)):
        raise TypeError('fname    need    to    be    string')
    check_call(_LIB.MXSymbolSaveToFile(self.handle, c_str(fname)))
