## Examples
### Creating a dataset from a list of files
```python
tokenizer = SPM_Tokenizer(vocab_size=5000, corpus='./stories.txt')
tokenizer = SPM_Tokenizer(vocab_model_file='./tokenizer_.model')
dataset = tokenizer.load_dataset(['./stories.txt'])
for (X, Y) in dataset:
X = np.array(X)
Y = np.array(Y)
```
### Creating a GPT Model
```python
GPT_Block = GPT(Decoder,
TokenAndPositionEmbedding,
vocab_size=5001,
)
GPT_Model = keras.Sequential()
GPT_Model.add(keras.Input(shape=(64,)))
GPT_Model.add(GPT_Block)
loss_fn = keras.losses.SparseCategoricalCrossentropy(from_logits=False)
GPT_Model.compile(optimizer='adam', loss=[loss_fn])
GPT_Model.summary()
Model: "sequential"

dataset.create_vocabs(10, 3) # Second language
# Create a map between the first and second languages
map_dict, reverse_dict = dataset.create_map(0, 1)
# Write 5 sentence pairs to a file (append mode: True)
dataset.write_dataset_to_file(map_dict, reverse_dict, max_len=3, n=5, file_path='dataset.txt', append=False)
# Overwrite file with new 5 pairs (append mode: False)
dataset.write_dataset_to_file(map_dict, reverse_dict, max_len=3, n=5, file_path='dataset.txt', append=True)
