Welcome to the world of AutoNLP, where automating the development of natural language processing models is not just a dream but a reality! In this guide, we will explore how to leverage AutoNLP to build an extractive question-answering model, specifically focused on answering questions about a given context. Let’s dive in!

Understanding the Basics: A Simple Analogy

Think of AutoNLP like a magical librarian who knows the right book to pull off the shelf based on your question. Instead of sifting through piles of books (text data), the librarian comes to you with the exact information you need. In our case, the “librarian” is the AutoNLP model that pulls answers from a provided context based on the question you ask.

Model Overview

• Problem Type: Extractive Question Answering
• Model ID: 24465518
• CO2 Emissions: 45.27 grams
• Validation Metrics: Loss – 0.5742

How to Use the Model

You can interact with the model using two different methods: through cURL or with the Python API. I’ll break it down for you!

Method 1: Using cURL

With cURL, you can send a POST request to access the model. Here’s how:

$ curl -X POST -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" -d '{"question": "Who loves AutoNLP?", "context": "Everyone loves AutoNLP"}' https://api-inference.huggingface.com/models/teacookies/autonlp-roberta-base-squad2-24465518

Method 2: Using Python API

If you prefer Python, you can use the following code to access the model:

import torch
from transformers import AutoModelForQuestionAnswering, AutoTokenizer

model = AutoModelForQuestionAnswering.from_pretrained("teacookies/autonlp-roberta-base-squad2-24465518", use_auth_token=True)
tokenizer = AutoTokenizer.from_pretrained("teacookies/autonlp-roberta-base-squad2-24465518", use_auth_token=True)

question, text = "Who loves AutoNLP?", "Everyone loves AutoNLP"
inputs = tokenizer(question, text, return_tensors="pt")

start_positions = torch.tensor([1])
end_positions = torch.tensor([3])

outputs = model(**inputs, start_positions=start_positions, end_positions=end_positions)
loss = outputs.loss
start_scores = outputs.start_logits
end_scores = outputs.end_logits

Troubleshooting Common Issues

While working with AutoNLP, you may encounter some common issues. Here’s how to troubleshoot them:

• Invalid API Key: Ensure that your API key is valid and correctly placed in the cURL command or Python script.
• Incorrect Model ID: Verify that you are using the correct model ID, which is 24465518 in this case.
• Tokenization Errors: Double-check that your inputs are formatted correctly. Ensure you are passing plain text without extra commas or quotations.
