# Try out in the Hosted inference API

In the right panel, you can try to the model (although it only handles a short sequence length).
Enter the document you want to summarize in the panel on the right.

# Model Loading
The model (based on a GPT2 base architecture) can be loaded in the following way:
```

from transformers import GPT2LMHeadModel, GPT2TokenizerFast



model = GPT2LMHeadModel.from_pretrained("philippelaban/summary_loop46")

tokenizer = GPT2TokenizerFast.from_pretrained("philippelaban/summary_loop46")

```

# Example Use
```

document = "Bouncing Boulders Point to Quakes on Mars. A preponderance of boulder tracks on the red planet may be evidence of recent seismic activity. If a rock falls on Mars, and no one is there to see it, does it leave a trace? Yes, and it's a beautiful herringbone-like pattern, new research reveals. Scientists have now spotted thousands of tracks on the red planet created by tumbling boulders. Delicate chevron-shaped piles of Martian dust and sand frame the tracks, the team showed, and most fade over the course of a few years. Rockfalls have been spotted elsewhere in the solar system, including on the moon and even a comet. But a big open question is the timing of these processes on other worlds — are they ongoing or did they predominantly occur in the past?"



tokenized_document = tokenizer([document], max_length=300, truncation=True, return_tensors="pt")["input_ids"].cuda()

input_shape = tokenized_document.shape

outputs = model.generate(tokenized_document, do_sample=False, max_length=500, num_beams=4, num_return_sequences=4, no_repeat_ngram_size=6, return_dict_in_generate=True, output_scores=True)

candidate_sequences = outputs.sequences[:, input_shape[1]:] # Remove the encoded text, keep only the summary

candidate_scores = outputs.sequences_scores.tolist()



for candidate_tokens, score in zip(candidate_sequences, candidate_scores):

    summary = tokenizer.decode(candidate_tokens)

    print("[Score: %.3f] %s" % (score, summary[:summary.index("END")]))
