Are you looking to enhance your natural language processing tasks with sentence similarity? The JonasChris2103 tiny llama embedder, a sentence-transformers model, is an excellent choice that maps sentences and paragraphs to a 2048-dimensional dense vector space. This allows for effective clustering, semantic search, and more. Let’s dive into how to use this model seamlessly!

Getting Started with the Model

To begin using this sentence embedder, ensure you have the sentence-transformers library installed. You can do this by running the following command:

pip install -U sentence-transformers

Using the Model

To use the model for sentence encoding, you can follow these simple steps. Let’s first take a look at the code snippet:

from sentence_transformers import SentenceTransformer

# Define your sentences
sentences = ["This is an example sentence", "Each sentence is converted"]

# Load the model
model = SentenceTransformer('jonaschris2103tiny_llama_embedder')

# Get embeddings
embeddings = model.encode(sentences)

# Print the embeddings
print(embeddings)

Understanding the Code

Let’s use an analogy to explain the above code. Imagine you’re a librarian (the model) who receives a stack of books (the sentences). Each book needs to be categorized into a specific section of a library (the embedding space). Here’s how it works:

• The librarian prepares a list of books that need sorting (the ‘sentences’ list).
• Next, the librarian looks at the library’s organization system (the ‘SentenceTransformer’) to determine where each book belongs.
• After this categorization, each book gets placed in its corresponding section (the embeddings are generated and printed).

Using the HuggingFace Transformers without Sentence-Transformers

If you prefer to use the model without the sentence-transformers library, here’s how you can do it:

from transformers import AutoTokenizer, AutoModel
import torch

# Define your sentences
sentences = ["This is an example sentence", "Each sentence is converted"]

# Load model from HuggingFace Hub
tokenizer = AutoTokenizer.from_pretrained('jonaschris2103tiny_llama_embedder')
model = AutoModel.from_pretrained('jonaschris2103tiny_llama_embedder')

# Tokenize sentences
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')

# Compute token embeddings
with torch.no_grad():
    model_output = model(**encoded_input)

# Define mean pooling
def mean_pooling(model_output, attention_mask):
    token_embeddings = model_output[0] 
    input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
    return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)

# Perform pooling
sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])

# Print the sentence embeddings
print("Sentence embeddings:")
print(sentence_embeddings)

Evaluation of the Model

To evaluate how well your model performs, you can check the Sentence Embeddings Benchmark. This provides an automated assessment of the model’s effectiveness.

Troubleshooting Tips

If you encounter any issues while using the JonasChris2103 tiny llama embedder, consider the following troubleshooting ideas:

• Ensure that all necessary libraries are installed and updated. You can reinstall with pip install --upgrade sentence-transformers transformers torch.
• Check if your input sentences are correctly formatted; they should be wrapped in quotes and separated by commas.
• If the model doesn’t seem to work as expected, try lowering the batch size in your encoding step.
