while executing the tf_elasticjob_on_k8s example, job fails with error.

cd examples/tensorflow/criteo_deeprec
kubectl apply -f autoscale_job.yaml

initial error messages as follows:

[root@localhost test]# kubectl get pods -n dlrover

 2024-05-13 19:13:25.419	
/bin/bash: line 0: cd: /home/examples/tensorflow/criteo_deeprec: No such file or directory

upon unpacking the image of registry.cn-hangzhou.aliyuncs.com/intell-ai/dlrover:deeprec_criteo_v1 it appears that the directory is missing. however there are files in the directory of /dlrover/examples/tensorflow/criteo_deeprec

I've changed the spec.containers.command of the examples/tensorflow/criteo_deeprec/autoscale_job.yaml/ file as follows for trying to remedy the issue:

              command:
                - /bin/bash
                - -c
                - "cd /dlrover/examples/tensorflow/criteo_deeprec \
                  && python -m dlrover.trainer.entry.local_entry \
                  --platform=Kubernetes --conf=train_conf.TrainConf \
                  --enable_auto_scaling=True"

the failure persists with the following error logs:

I have fixed the example in #1141 . You can try the example with the latest master branch.

You can use kubectl to delete a worker and a new work will restart.
