How can I get deterministic results from map_embeddings.py?

I'm running the below command, however my results are not deterministic. Is there a way to do so?  (I'm debugging the pipeline, so would like a fully reproducible run)
```
export OMP_NUM_THREADS=1
python3 $VECMAP/map_embeddings.py \
        --unsupervised -v --seed 1 \
        $working/step3/emb.src $working/step3/emb.trg \
        $root/emb.src $root/emb.trg
```
