|
### How to use |
|
|
|
```python |
|
from huggingface_hub import hf_hub_url, cached_download |
|
import joblib |
|
import pandas as pd |
|
|
|
REPO_ID = "julien-c/wine-quality" |
|
FILENAME = "sklearn_model.joblib" |
|
|
|
|
|
model = joblib.load(cached_download( |
|
hf_hub_url(REPO_ID, FILENAME) |
|
)) |
|
|
|
# model is a `sklearn.pipeline.Pipeline` |
|
``` |
|
|
|
#### Get sample data from this repo |
|
|
|
```python |
|
data_file = cached_download( |
|
hf_hub_url(REPO_ID, "winequality-red.csv") |
|
) |
|
winedf = pd.read_csv(data_file, sep=";") |
|
|
|
|
|
X = winedf.drop(["quality"], axis=1) |
|
Y = winedf["quality"] |
|
|
|
print(X[:3]) |
|
``` |

|
|
|
|
|
#### Get your prediction |
|
|
|
```python |
|
labels = model.predict(X[:3]) |
|
# [5, 5, 5] |
|
``` |
|
|
|
#### Eval |
|
|
|
```python |
|
model.score(X, Y) |
|
# 0.6616635397123202 |
|
``` |
