@dosu Can you give me a simple configuration for access Langsmith while I am running my langchain or langgraph please?

[dosubot[bot]]

To access Langsmith while running your Langchain or Langgraph, you can use the following simple configuration:

1. Install the required packages:

   %pip install -U langchain-community langgraph langchain-anthropic tavily-python langgraph-checkpoint-sqlite

2. Set up your LangSmith API key and enable tracing:

   import getpass
   import os
   
   os.environ["LANGCHAIN_TRACING_V2"] = "true"
   os.environ["LANGCHAIN_API_KEY"] = getpass.getpass("Enter your LangSmith API key: ")

3. Clone an example dataset:

   from langsmith import Client as LangSmithClient
   
   ls_client = LangSmithClient()
   
   dataset_name = "LangSmith Few Shot Datasets Notebook"
   dataset_public_url = (
       "https://smith.langchain.com/public/55658626-124a-4223-af45-07fb774a6212/d"
   )
   
   ls_client.clone_public_dataset(dataset_public_url)

4. Initialize the document loader and load documents:

   from langchain_core.document_loaders import LangSmithLoader
   
   loader = LangSmithLoader(
       dataset_name=dataset_name,
       content_key="question",
       limit=50,
   )
   
   docs = loader.load()
   print(docs[0].page_content)

5. Optional: Configure LangSmith for tracing, monitoring, and debugging:

   export LANGCHAIN_TRACING_V2=true
   export LANGCHAIN_API_KEY=<your-api-key>
   export LANGCHAIN_PROJECT=<your-project>  # if not specified, defaults to "default"

6. Start a LangServe instance:

   If you are inside your project directory, you can spin up a LangServe instance directly by:

   langchain serve

   This will start the FastAPI app with a server running locally at http://localhost:8000.

This configuration will allow you to access Langsmith while running your Langchain or Langgraph ^{[1][2][3][4][5]}.
