DSPy Visualization Quickstart

LangWatch DSPy Visualization allows you to start tracking your DSPy experiments in real-time and easily follow the progress, track costs and debug each step.

​

1. Install the Python library

• Notebook
• Command Line

!pip install langwatch

​

2. Login to LangWatch

Import and authenticate the LangWatch SDK:

import langwatch

langwatch.login()

Be sure to login or create an account on the link that will be displayed, then provide your API key when prompted.

​

3. Start tracking

Before your DSPy program compilation starts, initialize langwatch with your experiment name and the optimizer to be tracked:

# Initialize langwatch for this run, to track the optimizer compilation
langwatch.dspy.init(experiment="my-awesome-experiment", optimizer=optimizer)

compiled_rag = optimizer.compile(RAG(), trainset=trainset)

​

Follow your experiment

Open the link provided when the compilation starts or go to your LangWatch dashboard to follow the progress of your experiments:

​

Wrapping up

With your experiments tracked on LangWatch, now it’s time to explore how is the training going, take a look at the examples, the llm calls, the different steps and so on, so you can understand and hypothesize where you could improve your DSPy program, and keep iterating!
