I am using load\_dataset to load my data which is basically files stored in a directory:

I load the data with:  
`dataset = load_dataset(path='/Users/petar/Documents/bert/data', split='train')`

Basically, only “train” split is available and my data is stored there. I also would like to get a eval or test split so I can do “per\_device\_eval\_batch\_size” in TrainingArguments. How can I make that split and specify split size?

Hi @petarulev ! You can use Datasets `train_test_split` function to create and adjust the size of each split:

```nohighlight
dataset.train_test_split(test_size=0.2)

```

Check out the docs [here](https://huggingface.co/docs/datasets/process#split) 🙂
