PowerPoint-Generative-AI

This library streamlines the utilization of GPT models for automatic PowerPoint content generation. It further offers a class for loading PowerPoints and performing semantic searches on slide content, enabling you to quickly pinpoint relevant information.

Setup

conda create -n 'powerpoint' python=3.10
conda activate powerpoint
pip install -r requirements.txt

How to use

from powerpoint_generative_ai import PowerPointGenerator, PowerPointAnalyzer


# set up two classes
ppt_gen = PowerPointGenerator(openai_key="...", model="gpt-4")
ppt_analyzer = PowerPointAnalyzer(openai_key="...", pinecone_key="...", pinecone_index="...", pinecone_env="...")

# generate powerpoints
powerpoint_files = [ppt_gen.create_powerpoint(user_input=user_text) for user_text in USER_TEXTS]

# load powerpoints into pinecone
ppt_analyzer.load(file_paths=powerpoint_files)

Custom Embeddings Function

By default, PowerPointAnalyzer utilizes OpenAI's text-embedding-ada-002 embeddings. However, an optional parameter custom_embeddings_function allows the use of a user-defined embeddings solution in place of OpenAI's.

This function should follow the following signature:

def custom_embeddings_function(texts: List[str]) -> List:
    # The function takes in a list of strings to calculate the embeddings for
    # ...
    # Return a list of lists that represent the embeddings of the input texts


# This can then be used when instantiating an analyzer class like this
ppt_analyzer = PowerPointAnalyzer(openai_key="...", pinecone_key="...", pinecone_index="...", pinecone_env="...", custom_embeddings_function=custom_embeddings_function)

Generating Alt-Text for Images

The PowerPointGenerator has a function create_alt_text_for_powerpoint. It takes two parameters; ppt_path (the path to the powerpoint) and device. The device param has a few options, namely (cuda, mps, cpu). The function generates alt-text for images, sets them as the descr attribute (alt text), then saves them back to the path it read it from. Here is an example snippet using the function:

from powerpoint_generative_ai.ppt_generator import PowerPointGenerator
ppt_gen = PowerPointGenerator(openai_key="...", model="gpt-4")
ppt_gen.create_alt_text_for_powerpoint(ppt_path="/path/to/slide_deck.pptx", device="mps")

The generated captions will also be logged for the user to see what has been generated.

Cleaning up index
