Ml agents namespace "input" can't be found in Unity.MLAgents.Extension

I Imported MlAgents and everything worked fine untill I also imported the Unity examples folder that caused multiple namespace errors. I don't know how to fix it Assets\ML-Agents\Examples\PushBlockWithInput\Scripts\PushBlockWithInputPlayerController.cs(1,33): error CS0234: The type or namespace name 'Input' does not exist in the namespace 'Unity.MLAgents.Extensions' (are you missing an assembly reference?) Assets\ML-Agents\Examples\PushBlockWithInput\Scripts\PushBlockWithInputPlayerController.cs(21,66): error CS0246: The type or namespace name 'IInputActionAssetProvider' could not be found (are you missing a using directive or an assembly reference?)
