Can we get calculated embeddings directly into variable?

`embed.py` script calculates embeddings of inputs in `sample-metadata.json` and stores them in output file `output.jsonl`

```
python scripts/embed.py \
--ids data/sample.ids --metadata data/sample-metadata.json \
--model ./model.tar.gz \
--output-file output.jsonl \
--vocab-dir data/vocab/ \
--batch-size 16 \
--cuda-device -1
```
Is there any way to call the function directly from python script and get the output embeddings in a variable? ...something like the web-api is doing but locally, offline
I do not want to load the model for each evaluation call
