Will this cause an error if single_grouped_weight is not in the signature of GroupedLinear.__init__()?
A better way may be

if is_te_min_version("2.14.0"):
    extra_kwargs["single_grouped_weight"] = getattr(config, "moe_single_grouped_weight", False)
    extra_kwargs["single_grouped_bias"] = getattr(config, "moe_single_grouped_bias", False)

Then pass them via **extra_kwargs.
