     Cycles are not allowed in a Pipeline.

+.. warning:: Ignored user inputs
+
+    If inputs are provided both by user in the `pipeline.run` method and as
+    `input_config` in a connect method, the user input will be ignored. Take for
+    instance the following pipeline, adapted from the previous one:
+
+    .. code:: python
+
+            pipe.connect("a", "b", input_config={"number2": "a.result"})
+            asyncio.run(pipe.run({"a": {"number1": 10, "number2": 1}, "b": {"number1": 4, "number2": 42}}))
+
+    The result will still be **15** because the user input `"number2": 42` is ignored.
