Passing a list of integers instead of a list of strings to torchtext.voca.lookup_indices CRASHES the kernel

🐛 Describe the bug

I was using torchtext to construct a vocabulary (v) and tokenize the input text. I just wanted to check the indices of the tokens and therefore used the method v.vocab.lookup_indices(). Accidentally, I passed the list of integers as an argument instead of the list of string as expected by the method. Then it crashed the Jupyter kernel (I am using colab notebook).

# Assume all necessary imports
v = build_vocab_from_iterator(yield_tokens(sentences),min_freq=1,specials=['<pad>','<unk>','<mask>'])
v.set_default_index(v['<unk>'])  
# the Jupyter kernel crashed after executing the statement below
v.vocab.lookup_indices([0,1,2])

I looked at the source code at https://pytorch.org/text/stable/_modules/torchtext/vocab/vocab.html#Vocab.lookup_indices and found that the type checking (of elements in the list) is missing in the function definition.

def lookup_indices(self, tokens: List[str]) -> List[int]:
        r"""
        Args:
            tokens: the tokens used to lookup their corresponding `indices`.

        Returns:
            The 'indices` associated with `tokens`.
        """
        return self.vocab.lookup_indices(tokens)
