+.. _cn_api_fluid_dygraph_jit_set_code_level:
+
+set_code_level
+-----------------
+
+.. py:function:: paddle.jit.set_code_level(level=100)
+设置代码级别，打印该级别 AST Transformer 转化后的代码。
+
+有两种方法设置代码级别：
+
+1. 调用函数 ``set_code_level``
+2. 设置环境变量 ``TRANSLATOR_CODE_LEVEL``
+
+.. note::
+    函数 ``set_code_level`` 的优先级高于环境变量 ``TRANSLATOR_CODE_LEVEL``。
+
+
+参数：
+  - **level** (int) - 打印的代码级别。默认值为100，这意味着打印的是所有 AST Transformer 转化后的代码。
+
+**示例代码**
+
+.. code-block:: python
+
+    import paddle
+    import os
+    paddle.jit.set_code_level(2)
+    # It will print the transformed code at level 2, which means to print the code after second transformer,
+    # as the date of August 28, 2020, it is CastTransformer.
+    os.environ['TRANSLATOR_CODE_LEVEL'] = '3'
+    # The code level is now 3, but it has no effect because it has a lower priority than `set_code_level`

+.. _cn_api_fluid_dygraph_jit_set_verbosity:
+
+set_verbosity
+-----------------
+
+.. py:function:: paddle.jit.set_verbosity(level=0)
+设置动态图转静态图的日志详细级别。
+
+有两种方法设置日志详细级别：
+
+1. 调用函数 ``set_verbosity``
+2. 设置环境变量 ``TRANSLATOR_VERBOSITY``
+
+.. note::
+    函数 ``set_verbosity`` 的优先级高于环境变量 ``TRANSLATOR_VERBOSITY``。
+
+
+参数：
+    - **level** (int) - 日志详细级别。值越大，表示越详细。默认值为0，表示不显示日志。
+
+**示例代码**
+
+.. code-block:: python
+
+    import os
+    import paddle
+    paddle.jit.set_verbosity(1)
+    # The verbosity level is now 1
+    os.environ['TRANSLATOR_VERBOSITY'] = '3'
+    # The verbosity level is now 3, but it has no effect because it has a lower priority than `set_verbosity`
