Load new trained model

Dear guys,

Thank you so much for your interesting works. I was able to train a new model based on [this instruction](https://github.com/huggingface/neuralcoref/blob/master/neuralcoref/train/training.md) and this [blog post](https://medium.com/huggingface/how-to-train-a-neural-coreference-model-neuralcoref-2-7bb30c1abdfe). However, I could not find anywhere a manual how to load the trained model.

To understand how the model was loaded using `add_to_pipe` function, I downloaded the model from this [URL](https://s3.amazonaws.com/models.huggingface.co/neuralcoref/neuralcoref.tar.gz) and unzipped it. Inside, I could saw the `static_vectors` and `tuned_vectors`. I guess those are exactly the like the ones I used to train the model. However, I also see new file which is `key2row` and I don't know what it is and how to construct this file.

Can some one please give me a small instruction how to do the inference for the trained model?
Thank you so much!
