model = LlamaForSequenceClassification.from_pretrained('path/to/your/model')
tokenizer = LlamaTokenizer.from_pretrained('path/to/your/tokenizer')
# Define an endpoint
@app.route('/chat', methods=['POST'])
def respond():
user_input = request.json.get('message')
inputs = tokenizer(user_input, return_tensors='pt')
output = model.generate(inputs['input_ids'])
response = tokenizer.decode(output[0], skip_special_tokens=True)
return jsonify({'response': response})
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000)
This Flask-based API ensures that your model remains responsive, processing incoming requests and sending relevant replies back to users. Once running, your chatbot will be accessible via its designated API.
