+  summary: "Finds unique elements along an axis of a tensor."
+  description: <<END
+This operation either returns a tensor `y` containing unique elements
+along the `axis` of a tensor. The returned unique elements is sorted
+in the same order as they occur along `axis` in `x`.
+This operation also returns a tensor `idx` and a tensor `count`
+that are the same size as the number of the elements in `x` along the
+`axis` dimension. The `idx` contains the index in the unique output `y`
+and the `count` contains the count in the unique output `y`.
+In other words, for an `1-D` tensor `x` with `axis = None:
+
+`y[idx[i]] = x[i] for i in [0, 1,...,rank(x) - 1]`
+
+For example:
+
+```
+# tensor 'x' is [1, 1, 2, 4, 4, 4, 7, 8, 8]
+y, idx, count = unique_with_counts(x)
+y ==> [1, 2, 4, 7, 8]
+idx ==> [0, 0, 1, 2, 2, 2, 3, 4, 4]
+count ==> [2, 1, 3, 1, 2]
+```
+
+For an `2-D` tensor `x` with `axis = 0`:
+
+```
+# tensor 'x' is [[1, 0, 0],
+#                [1, 0, 0],
+#                [2, 0, 0]]
+y, idx, count = unique_with_counts(x, axis=0)
+y ==> [[1, 0, 0],
+       [2, 0, 0]]
+idx ==> [0, 0, 1]
+count ==> [2, 1]
+```
+
+For an `2-D` tensor `x` with `axis = 1`:
+
+```
+# tensor 'x' is [[1, 0, 0],
+#                [1, 0, 0],
+#                [2, 0, 0]]
+y, idx, count = unique_with_counts(x, axis=1)
+y ==> [[1, 0],
+       [1, 0],
+       [2, 0]]
+idx ==> [0, 1, 1]
+count ==> [1, 2]
+```
