Need preprocessor config error

[mtkgeek]

Hi, I'm trying to run the phi3-vision model using local files. I followed the instructions but ran into this error

panicked at mistralrs-core/src/pipeline/vision.rs:192:22: Need preprocessor config

Even though the instructions do not say a preprocessor config file is needed, I added that as well but still ran into the same error. I'm on a Mac btw

MY CODE

from mistralrs import Runner, Which, ChatCompletionRequest, VisionArchitecture

runner = Runner(
    which=Which.VisionPlain(
        model_id="/Users/path/to/my/phi3v_model",
        tokenizer_json=None,
        repeat_last_n=64,
        arch=VisionArchitecture.Phi3V,
    ),
)

res = runner.send_chat_completion_request(
    ChatCompletionRequest(
        model="phi3v",
        messages=[
            {
                "role": "user",
                "content": [
                    {

                        },
                    },

Hi @mtkgeek, I just merged #489 which should fix this. As you are using the Python API, can you please follow the instructions to install from source, and try it again?

[mtkgeek]

Oh nice. I'm using the pip version. I tried installing from source but keep running into errors when I run pip install maturin[patchelf].

I guess I'll just wait for these changes to make it to pypi.

@mtkgeek I just released v0.1.23 which includes this fix. Can you please try it again after a pip reinstall?

[mtkgeek]

Thanks for the update @EricLBuehler. Now pip install doesn't work though

@mtkgeek thank you for reporting this, can you please try it again after you update via pip - it should be fixed?

[mtkgeek]

@EricLBuehler the new version installs but the original problem still persists. PanicException: Need preprocessor config when I run the code.

Can you please paste the output of ls /Users/path/to/my/phi3v_model?

[mtkgeek]

Sure @EricLBuehler . It's

config.json                             model.safetensors.index.json
model-00001-of-00002.safetensors        tokenizer.json
model-00002-of-00002.safetensors        tokenizer_config.json

[EricLBuehler]

Ah ok! I think I must have forgotten to update the docs. As documented here now, if you add preprocessor_config.json this should work.

[mtkgeek]

Thanks, it works now. I also wanted to point out that I can see Loading model /Users/path/to/my/phi3v_model on cpu. is this normal, I was expecting "on metal" or "on mps" ?

[EricLBuehler]

Ok, that is good that it works. Regarding the device, can you close this issue and open another for that?
