Example run error

[Biyi-lab]

Hi
when I try to run the StartExperimentSFCEdge and SimpleExampleInterCloud codes, some error occurs:
The run configuration is set according to the tutorial.

SimpleExampleInterCloud:
java.lang.NullPointerException at org.cloudbus.cloudsim.sdn.example.SimpleExampleInterCloud.getAllHostList(SimpleExampleInterCloud.java:212) at org.cloudbus.cloudsim.sdn.example.SimpleExampleInterCloud.startSimulation(SimpleExampleInterCloud.java:192) at org.cloudbus.cloudsim.sdn.example.SimpleExampleInterCloud.main(SimpleExampleInterCloud.java:168) Unwanted errors happen

StartExperimentSFCEdge:
java.lang.Exception: net : Error - this entity has no PEs. Therefore, can't process any Cloudlets. at org.cloudbus.cloudsim.Datacenter.<init>(Datacenter.java:104) at org.cloudbus.cloudsim.sdn.physicalcomponents.SDNDatacenter.<init>(SDNDatacenter.java:61) at org.cloudbus.cloudsim.sdn.example.StartExperimentSFCEdge.createSDNDatacenter(StartExperimentSFCEdge.java:441) at org.cloudbus.cloudsim.sdn.example.StartExperimentSFCEdge.createPhysicalTopology(StartExperimentSFCEdge.java:377) at org.cloudbus.cloudsim.sdn.example.StartExperimentSFCEdge.main(StartExperimentSFCEdge.java:291)

java.lang.NullPointerException at org.cloudbus.cloudsim.sdn.example.StartExperimentSFCEdge.getAllHostList(StartExperimentSFCEdge.java:360) at org.cloudbus.cloudsim.sdn.example.StartExperimentSFCEdge.startSimulation(StartExperimentSFCEdge.java:340) at org.cloudbus.cloudsim.sdn.example.StartExperimentSFCEdge.main(StartExperimentSFCEdge.java:316)

Any helpful answer will be appreciated! Thank you!
