Encode input text

input_text = "Hello, how are you?" input_ids = tokenizer.encode(input_text, return_tensors='pt')

Generate text

output = model.generate(input_ids, max_length=100, temperature=0.7, num_return_sequences=1)

Decode the output

output_text = tokenizer.decode(output[0], skip_special_tokens=True)

print(output_text)
