Is TorchText implemented? #1381

Open przemyslawbak opened 2 weeks ago

przemyslawbak commented 2 weeks ago

For TorchSharp text classification example there is TorchText used to load data set.

I am not sure what I am doing wrong, but I can not find any usings to import this library.

For TorchSharp MNIST example I did manage to find and install proper NuGet to use torchvision.

Is TorchText implemented for .NET?

If not, alternatively, how can I load data from CSV file? I do not know what data type should be used for var reader in the example? Im confused.

I think we don't have torchtext support currently, and I've found the class in Examples.Utils.

We do not have that implemented.

Maybe @luisquintanilla can comment on some of the text-based preprocessing primitives we've added to ML.NET -- there's a few new tokenizers there, which should be usable with TorchSharp.

Could you share your view which of the recent progress in ML.NET, regarding deep NLP, could be relevant for advancing TorchText project using TorchSharp?
