Hello @excavator-matt 

Thanks for your response. 

I dont have a workspace to test on 17.2 BETA ML cluster. Highly recommended to use LTS based cluster. 

however: You can try running upgrade transformers and run sentence_transformers. 

After the pip install --upgrade transformers, run from sentence_transformers import SentenceTransformer again in your 17.2 ML Beta cluster. If it still crashes with the undefined symbol error, the upgrade alone might not have fixed the flash-attn compatibility issue (as transformers 4.41.2 might still rely on the runtime's pre-built flash-attn 2.7.4.post1).

Thank you.
