llama.cpp ./embedding

Is there no rust binding to get the embeddings?

Using llama.cpp one would use:

./embedding -m ./path/to/model --log-disable -p "Hello World!" 2>/dev/null

have you tried this

rust-llama.cpp/src/lib.rs

Line 287 in baa1bcf

pub fn embeddings(

method ?

this will get you the embeddings for the prompt

@mdrokz thank you for your response.

I tried it before trying the direct llama.cpp ./embedding executable.

The function would always return an empty vector:

[]

I tried multiple configurations but could not fix the issue.

Alright i will test on my end see whats happening. Thanks

I was using zephyr-7B-alpha-GGUF with:

context_size: 8192 
n_batch: 512 
embeddings: true

without any GPU assistance.

Note:
There also was some strange behavior regarding n_batch and n_token where a longer prompt (still way below the context length) lead to an unexpected error:

GGML_ASSERT: n_token <= n_batch

Right now my workaround is to use a rust wrapper (Command::new) around the ./embedding binary and parse the float values from stdout back into a string, then vector. The only parameter I set is --ctx-size 8192 and --mlock.
I imagine this is less efficient as the model needs to be reloaded for each call.
