+      This operation samples input X by using bilinear interpolation based on 
+      flow field grid, which is usually gennerated by affine_grid. The grid of
+      shape [N, H, W, 2] is the concatenation of (grid_x, grid_y) coordinates 
+      with shape [N, H, W] each, where grid_x is indexing the 4th dimension 
+      (in width dimension) of input data x and grid_y is indexng the 3rd 
+      dimention (in height dimension), finally results is the bilinear 
+      interpolation value of 4 nearest corner points.
+
+      Step 1:
+        Get (x, y) grid coordinates and scale to [0, H-1/W-1].
+
+        grid_x = 0.5 * (grid[:, :, :, 0] + 1) * (W - 1)
+        grid_y = 0.5 * (grid[:, :, :, 1] + 1) * (H - 1)
+
+      Step 2:
+        Indices input data X with grid (x, y) in each [H, W] area, and bilinear 
+        interpolate point value by 4 nearest points.

+    The hash algorithm we used was xxHash - Extremely fast hash algorithm
+    (https://github.com/Cyan4973/xxHash/tree/v0.6.5)
+
+    A simple example as below:
+
+    .. code-block:: text
+
+        Given:
+
+        # shape [2, 2]

+
+        input.lod = [[0, 2]]
+
+        hash_size = 10000
+
+        num_hash = 4
+
+        Then:
+
+        Hash op will take all number in input's 2nd dimension as hash algorithm's
+        input for each time. Each input will be hashed for 4 times, and get an
+        array whose length is 4. Each value in the array ranges from 0 to 9999.
+
+        # shape [2, 4]

+            [[9662], [9217], [1129], [8487]],
+            [[8310], [1327], [1654], [4567]],
+        ]
+
+        output.lod = [[0, 2]]
+
+    Args:
+        input (Variable): The input variable which is a one-hot word. The
+            dimensions of the input variable must be 2.
+        hash_size (int): The space size for hash algorithm. The output value
+            will keep in the range:math:`[0, hash_size - 1]`.
         num_hash (int): The times of hash, default 1.
         name (str, default None): The name of this layer.
