Hello!

I really appreciate that you have upgraded this project!

However, there are still 2 tests that cannot pass. testGenerateInfill and testCompleteInfillCustom. The outputs would be something like this:

{"tid":"130286006306496","timestamp":1712589265,"level":"INFO","function":"update_slots","line":1772,"msg":"all slots are idle"}
{"tid":"130286006306496","timestamp":1712589265,"level":"INFO","function":"launch_slot_with_task","line":1066,"msg":"slot is processing task","id_slot":0,"id_task":21}
{"tid":"130286006306496","timestamp":1712589265,"level":"INFO","function":"update_slots","line":2082,"msg":"kv cache rm [p0, end)","id_slot":0,"id_task":21,"p0":0}

I have built with the command cmake .. -DBUILD_SHARED_LIBS=ON -DLLAMA_CUDA=ON -DLLAMA_CURL=ON.

Also, I have tested vanilla llama.cpp of tag b2619, with the same build args above and the same inference args (shown below), and it worked without crash:

./server -m PATH_TO_LLAMA_CHAT -ngl 43 --embeddings

and

curl --request POST \
    --url http://localhost:8080/completion \
    --header "Content-Type: application/json" \
    --data '{                                                                                                                                                                              
        "n_predict": 10,
        "input_prefix": "def remove_non_ascii(s: str) -> str:\n    \"\"\" ",
        "logit_bias": [[2, 2.0]],
        "stop": ["\"\"\""],
        "seed": 42,
        "input_suffix": "\n    return result\n",
        "temperature": 0.95,
        "prompt": ""
}'

Anyway, other java tests have been passed.

Thanks!
