 # InfiAgent-DABench
 This example is used to solve the InfiAgent-DABench using Data Interpreter (DI), and obtains 94.93% accuracy using gpt-4o.
 
-## Dataset
+## Dataset download
 ```
 cd /examples/di/InfiAgent-DABench
 git clone https://github.com/InfiAgent/InfiAgent.git
 mv InfiAgent/examples/DA-Agent/data ./
 ```
+## Special note:
+When doing DABench testing, you need to set the ExecuteNbCode() init to:
+```
+class ExecuteNbCode(Action):
+    """execute notebook code block, return result to llm, and display it."""
+
+    nb: NotebookNode
+    nb_client: NotebookClient
+    console: Console
+    interaction: str
+    timeout: int = 600
+
+    def __init__(
+        self,
+        nb=nbformat.v4.new_notebook(),
+        timeout=600,
+    ):
+        super().__init__(
+            nb=nbformat.v4.new_notebook(),#nb,
+            nb_client=NotebookClient(nb, timeout=timeout),
+            timeout=timeout,
+            console=Console(),
+            interaction=("ipython" if self.is_ipython() else "terminal"),
+        )
+```
+The path of ExecuteNbCode() is: 
+```
+metagpt.actions.di.execute_nb_code
+```
+Instead of using the original nb initialization by default.
 ## How to run
 ```
 python run_InfiAgent-DABench_single.py --id x   # run a task, x represents the id of the question you want to test
