Sure! Here's a step-by-step tutorial on using models on Hugging Face:
1. Install the Transformers library:
```
!pip install transformers
```
2. Import the necessary libraries:
```
from transformers import AutoTokenizer, AutoModelForSequenceClassification, pipeline
```
3. Choose a pre-trained model from the Hugging Face model hub. For this tutorial, we'll use the DistilBERT model for sentiment analysis:
```
model_name = "distilbert-base-uncased-finetuned-sst-2-english"
```
4. Load the tokenizer and model:
```
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)
```
5. Create a pipeline for sentiment analysis:
```
sentiment_pipeline = pipeline('sentiment-analysis', model=model, tokenizer=tokenizer)
```
6. Use the pipeline to analyze some text:
```
text = "I loved the new movie, it was amazing!"
result = sentiment_pipeline(text)
print(result)
```
This should output:
```
[{'label': 'POSITIVE', 'score': 0.9998785252571106}]
```
And that's it! You can now use Hugging Face to quickly and easily use pre-trained models for various NLP tasks.
