To create a local large language model using Hugging Face’s Transformers library and F#/.NET, you can follow these steps:

Install Required Packages:

Install the HuggingFace.Transfomers package from NuGet. You can use the Package Manager Console or the .NET CLI to install it:

dotnet add package HuggingFace.Transfomers

Install any additional packages you may need for your interactive interface, such as FSharp.Compiler.Service or Fable.

Load Pretrained Model:

Choose a pre-trained language model from the Hugging Face Model Hub. You can find various models trained on large datasets, such as GPT-2 or GPT-3.

The concept of using pre-trained language models is often referred to as transfer learning.

In your F# code, use the AutoModel class from the HuggingFace.Transfomers package to load the pre-trained model:

open Huggingface.Transfomers // Load the pretrained model let model = AutoModel.ForPretrainedModel("model_name")

Tokenization:

Tokenize the input text using the tokenizer associated with the loaded model:

// Load the corresponding tokenizer let tokenizer = AutoTokenizer.ForModel(model_name) // Tokenize the input text let input = "Your input text" let tokenizedInput = tokenizer.Encode(input)

Inference:

Feed the tokenized input to the loaded model for inference and obtain the model’s response:

// Inference let response = model.Forward(tokenizedInput)

Postprocessing:

Convert the model’s response back to human-readable text using the tokenizer.

// Decode the model's response let decodedResponse = tokenizer.Decode(response)

Interactive Interface:

• Build your interactive interface using F# libraries like FSharp.Compiler.Service or Fable.

• Handle user input and call the tokenization, inference, and postprocessing steps accordingly.

• Display the model’s response to the user.

Here’s an example of an interactive F# console application that uses Hugging Face’s Transformers library to create a local language model:

We’re serious about HuggingFace. Especially the face!

open Huggingface.Transfomers

// Load the pretrained model
let model = AutoModel.ForPretrainedModel("model_name")// Load the corresponding tokenizer
let tokenizer = AutoTokenizer.ForModel("model_name")// Interactive loop
let rec interactiveLoop () =
    printfn "Enter your input:"
    let input = Console.ReadLine()
    let tokenizedInput = tokenizer.Encode(input)
    let response = model.Forward(tokenizedInput)
    let decodedResponse = tokenizer.Decode(response)
    printfn "Model response: %s" decodedResponse
    interactiveLoop ()// Start the interactive loop
interactiveLoop ()

Remember to replace "model_name" with the actual name of the pre-trained model you want to use.

This entire process might run on your local system, but in case you want to really get into the whole business and ask some very open-ended questions to fully trained and optimized transformers, running the transformers on the cloud might be the best solution.

Amazon has created an interesting tool: Amazon SageMaker Studio which looks similar to a Jupyter Notebook but runs on the cloud. Make sure you estimate model costs, your own bank balance, and your current budget before you ever start with say, the BLOOM LLM (176 Billion parameters, FYI).

Budget or get broke very fast. Be careful! We’re paying in USD!

Summary

The code provided allows you to create a local large language model using Hugging Face’s Transformers library and F#/.NET. It works locally by loading the pre-trained model and tokenizer into memory and performing inference on the local machine.

However, it’s important to note that the size and complexity of large language models may require significant computational resources and memory. Therefore, depending on the specific model and hardware available on your local machine, you might encounter resource limitations when working with very large models.

If you’re working with a particularly large language model that exceeds the capabilities of your local machine, you may need to consider utilizing cloud resources, such as cloud-based GPUs or TPUs, to perform inference efficiently. Cloud platforms like Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure offer services for running deep learning models at scale.

In such cases, you would typically deploy your F# code to the cloud platform of your choice and leverage the cloud’s computational resources to handle the model’s computation. Your local interface can then communicate with the deployed model via API calls or other integration methods.

The code provided can serve as a foundation for building the interactive interface and handling the communication with the model, regardless of whether it is executed locally or with cloud resources. The decision on where to run the model depends on the specific requirements, available resources, and scalability needs of your application.

Code-Based HuggingFace API

From the HuggingFace website documentation:

If you need to create a repo from the command line:

$pip install huggingface_hub
#You already have it if you installed transformers or datasets

$huggingface-cli login
#Log in using a token from huggingface.co/settings/tokens
#Create a model or dataset repo from the CLI if needed
$huggingface-cli repo create repo_name --type {model, dataset, space}

Clone your model or dataset locally

#Make sure you have git-lfs installed
#(https://git-lfs.github.com)
$git lfs install
$git clone https://huggingface.co/username/repo_name

Then add, commit and push any file you want, including large files

# save files via `.save_pretrained()` or move them here
$git add .
$git commit -m "commit from $USER"
$git push

In most cases, if you’re using one of the compatible libraries, your repo will then be accessible from code, through its identifier: username/repo_name

For example for a transformers model, anyone can load it with:

tokenizer = AutoTokenizer.from_pretrained("username/repo_name")
model = AutoModel.from_pretrained("username/repo_name")

Surprisingly simpler and more accessible than one might think. That’s the true power of the HuggingFace API.

Or you can use the pipeline library, which does both tokenization and loading pre-trained weights (transfer learning).

Of course, we need to discuss the HuggingFace Hub:
