ValueError: Stop argument for islice() must be None or an integer: 0 <= x <= sys.maxsize.

Hi,

I am getting
ValueError: Stop argument for islice() must be None or an integer: 0 <= x <= sys.maxsize.

My code:

databunch_lm = BertLMDataBunch.from_raw_corpus(
    data_dir=DATA_PATH,
    text_list = examples,
    tokenizer = loaded_tokenizer,
    batch_size_per_gpu=128,
    max_seq_length=32,
    model_type="bert",
    multi_gpu=False,
    logger=logger,
    test_size=0.01
)

Stack trace:

ValueError                                Traceback (most recent call last)
