If none of the other kernels in the graph are getting called then it is quite likely that the graph is not being run at all.
In order to confirm k['eles/limiter'] is not an empty list you need to print it or take it length.

You are right, k[‘eles/limiter’] is an empty list. But why this happened?
Thanks a lot.
For the same reason that k['eles/sadfasfd'] will return an empty list: the kernel does not exist; or rather a kernel by that name is not provided by the Elements class.
