## Model description |
|
|
|
This model was fine-tuned with the purpose of performing the task of abstractive summarization. |
|
|
|
|
|
## Training and evaluation data |
|
|
|
Fine-tuned on cnn_dailymail training set |
|
Evaluated on cnn_dailymail test set |
|
|
|
## How to use model |
|
|
|
1. Loading the model |
|
|
|
```python |
|
import torch |
|
from peft import PeftModel, PeftConfig |
|
from transformers import AutoModelForSeq2SeqLM, AutoTokenizer |
|
|
|
# Load peft config for pre-trained checkpoint etc. |
|
peft_model_id = "emonty777/QLoRA-Flan-T5-Small" |
|
|
|
config = PeftConfig.from_pretrained(peft_model_id) |
|
|
|
# load base LLM model and tokenizer / runs on CPU |
|
model = AutoModelForSeq2SeqLM.from_pretrained(config.base_model_name_or_path) |
|
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path) |
|
|
|
# load base LLM model and tokenizer for GPU |
|
model = AutoModelForSeq2SeqLM.from_pretrained(config.base_model_name_or_path, load_in_8bit=True, device_map={"":0}) |
|
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path) |
|
|
|
# Load the Lora model |
|
model = PeftModel.from_pretrained(model, peft_model_id, device_map={"":0}) |
|
model.eval() |
|
``` |
|
2. Generating summaries |
|
|
|
```python |
|
text = "Your text goes here..." |
|
|
|
# If you want to use CPU |
|
input_ids = tokenizer(text, return_tensors="pt", truncation=True).input_ids |
|
# If you want to use GPU |
|
input_ids = tokenizer(text, return_tensors="pt", truncation=True).input_ids.cuda() |
|
# Adjust max_new_tokens based on size. This is set up for articles of text |
|
outputs = model.generate(input_ids=input_ids, max_new_tokens=120, do_sample=False) |
|
|
|
print(f"input sentence: {sample['article']}\n{'---'* 20}") |
|
print(f"summary:\n{tokenizer.batch_decode(outputs.detach().cpu().numpy(), skip_special_tokens=True)[0]}") |
|
|
|
``` |
|
|
|
|
|
