DSPy Explained in Simple Words with Easy Example

 In this video, I am going to explain DSPy in simple words with a simple example. If, by end of the video, you are still unable to understand what DSPy is I will return your money. Guaranteed. 

Code Used:

!pip install dspy-ai

!pip install openai~=0.28.1

import dspy

class ShakespeareanTranslation(dspy.Signature):

    """Translate simple english to Shakespearean english."""

    simple_english = dspy.InputField()

    shakespearean_english = dspy.OutputField()

   

from google.colab import userdata

OPENAI_API_KEY=userdata.get('OPENAI_API_KEY')

turbo = dspy.OpenAI(model='gpt-3.5-turbo', max_tokens=1000, api_key=OPENAI_API_KEY)

dspy.settings.configure(lm=turbo)

from dspy.signatures.signature import signature_to_template

shakespeare_translation_as_template = signature_to_template(ShakespeareanTranslation)

class CoT(dspy.Module):

    def __init__(self):

        super().__init__()

        self.prog = dspy.ChainOfThought(ShakespeareanTranslation)

   

    def forward(self, simple_english):

        return self.prog(simple_english=simple_english)

c = CoT()

c.forward("You should relax and have fun while it lasts.")
