+    The time distributed layer.
+
+    Time distributed is a wrapper which allows to apply a layer to every temporal slice of an input.
+    And the input should be at least 3D.
+    There are two cases in the implementation.
+    When reshape_with_axis provided, the reshape method will be chosen, which is more efficient;
+    otherwise, the method of dividing the inputs along time axis will be used, which is more general.
+    For example, reshape_with_axis could not be provided when deal with batch normal.
+
+    Args:
+        layer(Union[Cell, Primitive]): The Cell or Primitive which will be wrapped.
+        time_axis(int): The axis of time_step.
+        reshape_with_axis(int): The axis which time_axis will be reshaped with. Default: 'None'.

+    Raises:
+        TypeError: If cell is not a Cell or Primitive.
