chain-server container keeps crashing (rag-app-text-chatbot.yaml)

I'm trying to deploy a basic RAG chatbot using the rag-app-text-chatbot.yaml file, but I'm running into issues with the chain-server container crashing shortly after startup. I believe I've properly followed the directions on https://nvidia.github.io/GenerativeAIExamples/latest/local-gpu.html. I'm using the v0.6.0 tag on the github repository. If I run docker logs on the chain-server container, here's the output I see:

Bắt đầu với rag-app-text-chatbot.yaml và startup traceback, sau đó đọc common/server.py, example/chains.py và common/utils.py ở khu vực import được báo cáo và phần thiết lập LLM. Sử dụng docker logs cho chain-server để tái hiện lỗi và kiểm tra phiên bản của các dependency liên quan. Hoàn tất khi ứng dụng chain-server khởi động xong và tiếp tục chạy với cấu hình này.
