AttributeError: 'module' object has no attribute 'grasping_test'

This error usually occurs when you try to access an attribute or method that does not exist in the module you are importing. In this case, it seems that you are trying to access a method called "grasping_test" from a module, but that method does not exist in that module.

To fix this error, you need to check the module and make sure that the "grasping_test" method exists in it. If it does not exist, you can either create the method yourself or use a different method that does exist in the module.
