| - **weight** (Tensor，可选) - 权重值，默认为 None。 如果给定权重则形状为 :math:`[C, ]` | ||
| - **reduction** (str，可选) - 指定应用于输出结果的计算方式，可选值有：``'none'``、``'mean'``、``'sum'``。默认为 ``'mean'``，计算 Loss 的均值；设置为 ``'sum'`` 时，计算 Loss 的总和；设置为 ``'none'`` 时，则返回原始 Loss。 | ||
| - **name** (str，可选) - 具体用法请参见 :ref:`api_guide_Name`，一般无需设置，默认值为 None。 | ||
