Multiple languages supports

[Ke Fang]

Because the CLIP model is language-dependent, if we use something like Multilingual-CLIP (supporting 40+ languages), the size of the Queryable app would exceed 1GB. And because of offline limitations, it's impossible to use a translation API, which is why Queryable currently only supports English.

I have added a script to export PyTorch models to Core ML. Therefore, if you're interested, you can train a CLIP model in your own language and integrate it into Queryable. New model additions are welcome : )

hello, @mazzzystar .

how to modify script to support Chinese-CLIP?

I try to convert https://github.com/OFA-Sys/Chinese-CLIP to Core ML via script but failed.

The two model architecture is different, that's why there is an error, you may change the network to fit Chinese-CLIP.

This is a fantastic project, and I'm very interested in it. I'm currently learning about this project, and I will attempt to provide multi-language support. If I succeed, I will update it here. Thank you to the author for their selfless sharing. This is truly an amazing project.

@Enternalcode That's very kind of you, thank you so much!
