lsq 训练量化error： name 'grad_factor' is not defined

[wangshankun]

name 'grad_factor' is not defined

这份代码不论is_tracing_state是否为true都会报错

              if is_tracing_state():
                    X = FakeQuantizeLearnablePerchannelAffine.apply(
                        X, self.scale, self.zero_point, self.ch_axis,
                        self.quant_min, self.quant_max, grad_factor)
                else:
                    X = _fake_quantize_learnable_per_channel_affine_training(
                        X, self.scale, self.zero_point, self.ch_axis,
                        self.quant_min, self.quant_max, grad_factor)

您好，按理不会报这个错，在调用grad_factor之前grad_factor都被定义了。
可否提供进一步的错误信息
