请先通过CI检测噢~

scalar的问题貌似是之前的一个pr有问题，已经revert了，重新merge一下develop分支即可

当前CI有几个问题仍然需要关注：

Coverage：单测提示超时。请在保证覆盖率的前提下，适当减少功能重复或不必要的单测用例
Static：代码风格报错，请按提示修改，或者用pre-commit刷下格式

python/paddle/fluid/tests/unittests/test_cosine_embedding_loss.py

+from __future__ import print_function
+
+import paddle
+import paddle.fluid as fluid


因为fluid目前是非公开API并在逐步清理退场中。这里请不要使用fluid API，避免增加后续清理工作。静态图下相关API请参考paddle.static，设备相关检查请换用paddle.device.is_compiled_with_cuda()，paddle.CPUPlace等等

+            return paddle.sum(scores)
+
+    fluid.data_feeder.check_variable_and_dtype(


同单测文件，这里也请不要显式使用fluid API。在文件开始引用了check_variable_and_dtype，这里直接使用这个就行，方便后续清理工作

+        dtype='{}'.format(label.dtype).replace("paddle.", ""),
+        value=0)
+    check_zero = fluid.layers.fill_constant(


同上，这里也请换用static下的api

+class TestFunctionCosineEmbeddingLoss(unittest.TestCase):
+    def setUp(self):
+        self.input1_np = np.random.random(size=(3, 3)).astype(np.float64)


单测中需要覆盖rfc设计文档中写到的测试用例，包括所有支持的dtype等

size可以适当设计一些不一样的case以及稍大的case

在我线下Windows paddle-gpu-0.0.0环境中，dtype为float32的计算result和numpy结果except如下图所示

差距在1e-8数量级上，应当是可以通过单测，但是不知道为什么只在window-inference中无法通过单测

出错代码在我上次commit中可以查看

The parameters of x1, x2, target in paddle.nn.functional.cosine_embedding_loss 's RFC must be same with parameters here.

According to the design requirements, our API requires the name parameter like other loss API.

Now changing parameters will lead to the modification of code and document. Can I just change x1, x2, target to input1, input2, label in RFC?
