+    Create a CTR reader for data feeding in Python
+
+    This layer returns a Reader Variable.
+    The Reader provides :code:`decorate_paddle_reader()` and
+    :code:`decorate_tensor_provider()` to set a Python generator as the data
+    source in Python side. When :code:`Executor::Run()` is invoked in C++
+    side, the data from the generator would be read automatically. Unlike
+    :code:`DataFeeder.feed()`, the data reading process and
+    :code:`Executor::Run()` process can run in parallel using
+    :code:`py_reader`. The :code:`start()` method of the Reader should be
+    called when each pass begins, while the :code:`reset()` method should be
+    called when the pass ends and :code:`fluid.core.EOFException` raises.
+    Note that :code:`Program.clone()` method cannot clone :code:`py_reader`.
+
+    Args:
+       capacity(int): The buffer capacity maintained by :code:`py_reader`.
+       thread_num(list|tuple): List of tuples which declaring data shapes.
+       batch_size(list|tuple): List of strs which declaring data type.
+       file_list(list|tuple): List of ints which declaring data lod_level.
+       slots(bool): Whether use double buffer or not.
+       name(basestring): The prefix Python queue name and Reader name. None will
+            be generated automatically.
+
+    Returns:
+       Variable: A Reader from which we can get feeding data.
+
+    Examples:
+
+        1. The basic usage of :code:`py_reader` is as follows:
