Description

I have a pretrained model.bin file which was earlier converted using OpenNMTPy converter using fp32 quantisation. Now i want to reduce the size of the model and thought of quantising it to int8. But, I was only able to find ways to quantise it upon loading of the model, not able to find how to save it for further use.

Any idea how it can be achieved?

Research direction

The issue mentions a model.bin file, the OpenNMTPy converter, and quantization during model loading, but names no repository files or tests. Start by locating the loading-time quantization and model serialization entry points, then determine whether an int8 model can be saved for later use. Done should include a documented, repeatable conversion path and coverage for loading the saved model.
