If applicable, add logs to help explain your problem.
You may also attach an `.ipynb` file to this issue if it includes relevant logs or output.

Start with inference/nlp/realtime/llm/opt30b/djl_deepspeed_deploy_opt30b.ipynb and run the model-loading step to confirm the reported InferenceEngine text-generation error. The issue does not provide reproduction steps or logs, so determine the failing notebook stage and collect the missing output; done means the cause and a supported resolution or limitation are documented.
