-    The OP creates a tensor of specified :attr:`shape` and :attr:`dtype`, and fills it with 1.
+    Create a Tensor of specified :attr:`shape` and :attr:`dtype` and fill it with 1.
 
     Args:
-        shape(tuple|list|Tensor): Shape of the Tensor to be created, the data type of shape is int32 or int64.
-        dtype(np.dtype|str, optional): Data type of output Tensor, it supports
-            bool, float16, float32, float64, int32 and int64. Default: if None, the data type is 'float32'.
-        name(str, optional): The default value is None. Normally there is no need for user to set this property. For more information, please refer to :ref:`api_guide_Name`
+        shape (tuple|list|Tensor): Shape of the Tensor to be created, the data type of shape should be int32 or int64.
+        dtype (np.dtype|str, optional): Data type of output Tensor, it should be one of
+            bool, float16, float32, float64, int32 and int64. If it is set to None, the data type will be float32.
+        name (str, optional): For details, please refer to :ref:`api_guide_Name`. Generally, no setting is required. Default: None.
     
     Returns:
-        Tensor: A tensor of data type :attr:`dtype` with shape :attr:`shape` and all elements set to 1.
+        Tensor: A Tensor of data type :attr:`dtype` with shape :attr:`shape` and all elements are 1.
