Example Code

import openai
from langsmith import traceable
import uuid
client = openai.Client()
session_id = str(uuid.uuid4())
@traceable(
    run_type="chain",
    name="OpenAI Assistant",
)
def assistant(
    messages: list[dict]
):
    return client.chat.completions.create(
        model="gpt-3.5-turbo",
        messages=[{"role": "system", "content": "You are a helpful assistant."}] + messages,
    ).choices[0].message
messages = [
    {"role": "user", "content": "hi! im bob"}
]
response = assistant(
    messages,
    langsmith_extra={"metadata": {"session_id": session_id}}
)
messages = messages + [
    response,
    {"role": "user", "content": "what's my name?"}
]
response = assistant(
    messages,
    langsmith_extra={"metadata": {"session_id": session_id}}
)

Description

I'm using the langsmith_extra session_id to send all related traces to a thread.
But now that I have the unique identifier for the thread, is there a simple way to get the langsmith link where this thread is shown?
The link is something like

Hey there, @the-krushnakant! I'm here to help you with any bugs, questions, or contributions while you wait for a human maintainer. Let's crack this code conundrum together! 🤖

To get the LangSmith trace link from the session ID, you can use the get_run_url method from the LangChainTracer class. This method retrieves the URL for the latest traced run. Here is an example of how you can use it:

from langchain_core.tracers.langchain import LangChainTracer
from langsmith import Client

# Initialize the LangChainTracer with your LangSmith client
client = Client(api_key="your_api_key")
tracer = LangChainTracer(client=client, project_name="your_project_name")

# Assuming you have already run your assistant function and have traces
try:
    trace_link = tracer.get_run_url()
    print(f"LangSmith trace link: {trace_link}")
except ValueError as e:
    print(f"Error retrieving trace link: {e}")

This method will return the URL for the latest run, which you can use to access the trace link directly ^[1].

Given thread id, I want the thread url.
Or even given project name, I want project url.

[dosubot[bot]]

To get the thread URL given a thread ID or the project URL given a project name, you can use the following formats:

1. Thread URL:

   https://smith.langchain.com/o/<organization-id>/projects/p/<project-id>/t/<thread-id>
   

2. Project URL:

   def _format_project_url(project_name: str) -> str:
       return f"https://smith.langchain.com/o/<organization-id>/projects/p/{project_name}"

For example, if you have the project name and thread ID, you can construct the URLs as follows:

organization_id = "your_organization_id"
project_id = "your_project_id"
thread_id = "your_thread_id"

thread_url = f"https://smith.langchain.com/o/{organization_id}/projects/p/{project_id}/t/{thread_id}"
project_url = f"https://smith.langchain.com/o/{organization_id}/projects/p/{project_id}"

print(f"Thread URL: {thread_url}")
print(f"Project URL: {project_url}")

Replace your_organization_id, your_project_id, and your_thread_id with the actual values.

This seems like a hacky way. Is there a better way to do this? maybe a way to get project id given project name?

[dosubot[bot]]

To get the project ID given the project name in a more robust way using the LangSmith API, you can use the client.create_project method. This method handles the creation of a project and returns the project object, which includes the project ID. Here is an example of how you can use this method:

import uuid
from some_langsmith_client_module import LangSmithClient, LangSmithError

def get_project_id(client: LangSmithClient, project_name: str, dataset_id: str, tags: list = None, project_metadata: dict = None):
    try:
        project_metadata = project_metadata or {}
        project_metadata["dataset_version"] = "some_version"  # Replace with actual version if needed
        project = client.create_project(
            project_name,
            reference_dataset_id=dataset_id,
            project_extra={"tags": tags} if tags else {},
            metadata=project_metadata,
        )
        return project.id
    except (HTTPError, ValueError, LangSmithError) as e:
        if "already exists " not in str(e):
            raise e
        uid = uuid.uuid4()
        raise ValueError(
            f"Test project {project_name} already exists. Please use a different name:"
            f"\n\nrun_on_dataset(\n    ...\n    project_name=\"{project_name} - {uid}\", # Update since {project_name} already exists\n)"
        )

# Example usage
client = LangSmithClient(api_key="your_api_key")
project_id = get_project_id(client, "my_project_name", "my_dataset_id")
print(f"Project ID: {project_id}")

This code snippet demonstrates how to create a project and retrieve its ID using the LangSmith API, handling potential errors robustly ^[1].

@dosu I want to get id of existing project

[dosubot[bot]]

To get the ID of an existing project given its name using the LangSmith API, you can use the following approach:

import requests

def get_project_id_by_name(api_url, api_key, project_name):
    headers = {
        'Authorization': f'Bearer {api_key}',
        'Content-Type': 'application/json'
    }
    response = requests.get(f'{api_url}/projects', headers=headers)
    
    if response.status_code == 200:
        projects = response.json()
        for project in projects:
            if project['name'] == project_name:
                return project['id']
    else:
        response.raise_for_status()

    return None

# Example usage
api_url = 'https://api.langsmith.com'
api_key = 'your_api_key_here'
project_name = 'your_project_name_here'

project_id = get_project_id_by_name(api_url, api_key, project_name)
if project_id:
    print(f'Project ID: {project_id}')
else:
    print('Project not found')

This code snippet sends a GET request to the LangSmith API to retrieve a list of projects and then searches for the project with the specified name to return its ID ^[1].
