Unloading models from memory

[tunot]

Hello, I've been working with this library, and I've noticed that when a translation is requested its respective model is loaded into memory to do the translation. That's expected, but afterward the model stays in memory indefinitely.

How do make it so the translation model is unloaded after it performs its task. I'm fine with any performance issues resulting from this. I just prefer rarely used languages to not take up memory so much. Thanks
