The model name can't be found from config.json for skops models

[merveenoyan]

I noticed for some skops models the inference API doesn't work so I wanted to debug it. It works for this one but not for this one (same behavior occurs on my local, as for widgets, model loading times out)

What happens when I send a request:

(base) ➜  ~ curl -X POST -d '{"data": {"attribute_0": ["material_7","material_3","material_2"],"attribute_1": ["material_8","material_8","material_6"],"attribute_2": ["5","5","6"],"attribute_3": ["8","8","9"],"loading": ["154.02","108.73","99.84"],"measurement_0" :["14","4","6"],"measurement_1": ["6","7","7"],"measurement_10": ["16.637","16.207","17.17"],"measurement_11": ["20.719","20.058","20.858"],"measurement_12": ["12.824","11.898","10.968"],"measurement_13": ["16.067","13.871","16.448"],"measurement_14": ["15.181","14.266","15.6"],"measurement_15": ["18.546","15.734","14.637"],"measurement_16": ["19.402","16.886","13.86"],"measurement_17": ["643.086","642.533","673.545"],"measurement_2": ["6","9","6"],"measurement_3": ["19.532","18.128","12"],"measurement_4": ["11.017","11.866","10.064"],"measurement_5": ["15.639","17.891","16.287"],"measurement_6": ["16.709","20.302","17.445"],"measurement_7": ["10.057","12","12.117"],"measurement_8": ["20.201","18.148","20.659"],"measurement_9": ["11.106","10.221","11.999"],"product_code": ["C","C","E"]}}' http://localhost:8000/
{"error":"An error occurred while loading the model: [Errno 2] No such file or directory: '/Users/mervenoyan/.cache/huggingface/hub/models--scikit-learn--tabular-playground/snapshots/a2caff2628a7b0d4ca7588c93cf44363d109f906/sklearn_model.joblib'"}          

Model file name, as specified in configuration file, is model.pkl so it should look for that and not for DEFAULT_FILENAME that is defined here.

Pinging @adrinjalali and @BenjaminBossan as they were interested.
I will dig into why it occurs for this model and fix it.

A way to debug this is to directly see what the model has in its information

from huggingface_hub import model_info
model_info("scikit-learn/Fish-Weight")
## vs
model_info("scikit-learn/tabular-playground")

You'll notice some differences in the config field

Ugh this is directly linked with #96 😂 The config is not parsed properly and that's why. I'm very tired of this, I think errors should be raised properly. Will propose a solution there.
