Missing "load_data" method

Hello, 

Inside **summarization.py**, we see the following code lines:

```python
    import utils
    summary, docs, templates, triplets = utils.load_data(log_path, template_path, 0, log_type)
``` 

However, this method is not present inside the **utils.py** file. 

Could you please indicate if whether this method is present in the repo? 

Thank you in advance.
