[WT-103] Unable to reproduce results

[DavidHerel]

Hi,

I have successfully done all the steps from original knn_lm.
Then I have tried to run your scripts:
python rq/fast_evaluate.py --preset wiki_valid --save_knns # Save the neighbors.
python rq/fast_evaluate.py --preset wiki_valid --save_exact # Save the exact vector distances.
python rq/fast_evaluate.py --preset wiki_valid --exact # Compute perplexity using exact vector distance.

But I got following error:

fast_evaluate.py: error: unrecognized arguments: --save_exact
