Bugs in the backend/server.py and script.sh

script.sh and server.py discrepancies

There are some serious issues in the backend...

The Issue:

1. script.sh

the script does not do what is expected of it in README.md ... this is done by https://github.com/SnehaChaursia in #188 but ill still add the PR anyway

2. server.py

Many of the libraries that it imports have some dependency modules that are deprecated. Reason for this maybe because they're too old to be maintained, or have been removed by the maintainers, or just renamed to something else.

When you try to import similarity library (like in backend/server.py and backend/Generator/main.py ) ... you get an import error...
reason: the jors_winkler module from library jellyfish doesnt exist anymore..
its been renamed to jors_winkler_similarity

In some computers with limited GPU, the issue occurred because the server.py script attempted to load a large model on a GPU with insufficient VRAM (1.96GB), causing a CUDA Out of Memory error

What I propose:

• Replace every instance of jors_winkler to jors_winkler_similarity

• Force use CPU instead of GPU if insufficient VRAM is present

• before running server.py , set the environment variable os.environ["PYTORCH_CUDA_ALLOC_CONF"] = "expandable_segments:True"
