sedna: Joint Inference Service is failed on the agent

I am deploying Example1：Using Joint Inference Service in Helmet Detection Scenario.

In the last step Create joint inference service, master is okay, but joint-inference-helmet-detection-little can’t work on the edge: you can see there is no pod on the edge(I have already had the big and little images locally and version is v0.4.3)

on the edge, edgemesh and sedna are okay, but there is no joint-inference-helmet-detection-little

docker logs k8s_lc_lc-zlrzg_sedna

I have already tried to uninstall sdena and restart it again, the problem still exists.
