[Arnauld Adjovi]

No model/vocab.txt
I suggest you to clone your repo out of initial directory, run it to make sure that everything is okay

[Renato Violin]

The vocab.txt is in the download file together the pre-trained checkpoint.
Make sure to extract and get the following structure:

electra_large_qa_model
    data
    model
        model.ckpt-64000
        vocab.txt
    tfrecords

Make sure to adjust the DATA_MODEL_DIR to electra_large_qa_model folder.
