- →Visualize model comparison
- →Select the best model for production
Dataset
View on Kaggle Matches Kaggle
Superstore Sales dataset — Order Date, Sales, Category, Region, etc.
*bleep* Load the dataset in the browser terminal:
from pyodide.http import open_url
import pandas as pd
df = pd.read_csv(open_url("/datasets/train.csv"))
print(df.shape)
print(df.columns.tolist()) Running locally? The file inside the Kaggle download is already named train.csv — drop it into the notebook's working directory and the code above runs unchanged (swap open_url(...) for "train.csv").
