Latest DJL dependencies cause incompatibility for PyTorch in MacOS x86_64

[tzolov]

DJL versions >= 0.29.0 doesn't support PyTorch for MacOS x86_64.

Additional context: https://github.com/spring-projects/spring-ai/commit/df17f08f5b7c22b31ac73893b90d621180856774#commitcomment-146828827

I just tested your suggestion and it's working without issues. My test case was really quite simple but it's the same that was failing yesterday on my laptop.

import org.junit.jupiter.api.Test;
import org.springframework.ai.embedding.EmbeddingModel;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class MainTest {

    @Autowired
    EmbeddingModel embeddingModel;

    @Test
    void generateSimpleEmbedding() {
        embeddingModel.embed("Simple text for embedding");
    }
}

Checking DJL documentation, they added a comment about this topic here.

Thank you for checking it out.

Looks like DJL is not going to try to provide some form of backward compatibility for MacOS x86_64.

The explicit downgrading to 0.28.0 seems to be the only workaround i can think of. Thanks for confirming it works. I'm coping it here for are reference. Perhaps we can add it to the Spring Ai docs as well:
