+This is a list of encoded sequences: a list of lists. As you can see, the lengths of the tokenized outputs are different. Tensors require a "rectangular" shape (like a matrix), so you won't be able to convert this list of lists directly to a tensor. To resolve this, you need to use padding, as we saw earlier.

 While the model accepts a lot of different arguments, only the input IDs are necessary. We'll explain what the other arguments do and when they are required later, 
 but first we need to take a closer look at the tokenizers that build the inputs that a Transformer model can understand.
