사전 준비사항 (Pre-requisites)

설정 (Setup)

Colab에서 이 노트북을 여는 경우라면 LlamaIndex 🦙 설치가 필요할 거예요.

% pip install llama-index-llms-databricks
!pip install llama-index
from llama_index.llms.databricks import Databricks
None of PyTorch, TensorFlow >= 2.0, or Flax have been found. Models won't be available and only tokenizers, configuration and file/data utilities can be used.

Terminal window

export DATABRICKS_TOKEN=<your api key>
export DATABRICKS_SERVING_ENDPOINT=<your api serving endpoint>

대안으로 LLM을 초기화할 때 API 키와 서빙 엔드포인트를 전달할 수도 있어요.

llm = Databricks(
    model="databricks-dbrx-instruct",
    api_key="your_api_key",
    api_base="https://[your-work-space].cloud.databricks.com/serving-endpoints/",
)

사용 가능한 LLM 모델 목록은 여기에서 확인할 수 있어요.

response = llm.complete("Explain the importance of open source LLMs")
print(response)

메시지 목록으로 chat 호출

from llama_index.core.llms import ChatMessage


messages = [
    ChatMessage(
        role="system", content="You are a pirate with a colorful personality"
    ),
    ChatMessage(role="user", content="What is your name"),
]
resp = llm.chat(messages)
print(resp)

스트리밍 (Streaming)

stream_complete 엔드포인트 사용

response = llm.stream_complete("Explain the importance of open source LLMs")
for r in response:
    print(r.delta, end="")

stream_chat 엔드포인트 사용

from llama_index.core.llms import ChatMessage


messages = [
    ChatMessage(
        role="system", content="You are a pirate with a colorful personality"
    ),
    ChatMessage(role="user", content="What is your name"),
]
resp = llm.stream_chat(messages)
for r in resp:
    print(r.delta, end="")
