• 问题描述：如何使用半精度训练？，卷积的dtype='float16'

self._conv = fluid.dygraph.Conv2D(self.full_name(),
                                          num_filters=num_filters,
                                          filter_size=filter_size,
                                          stride=stride,
                                          padding=padding,
                                          dilation=dilation,
                                          act=None,
                                          dtype='float16',
                                          bias_attr=bias_attr,
                                          param_attr=fluid.ParamAttr(
                                              initializer=fluid.initializer.MSRAInitializer(False))
                                          )

    def forward(self, inputs):
        # inputs.dtype = 'float16'
        x = self._conv(inputs)

会出现以下错误：
