+## Build error fix applied
+
+The previous package used `python_version: 3.10` without quotes in `README.md`. In YAML, that can be interpreted as `3.1`, which makes Hugging Face try to pull `python:3.1`. This package fixes it by using `python_version: "3.10"`.

+# Fix Notes
+
+The build error came from Hugging Face reading the YAML metadata value:
+
+python_version: 3.10
+
+as Python 3.1.
+
+This package fixes the metadata by changing it to:
+
+python_version: "3.10"
+
+It also quotes the Gradio SDK version for consistency:
+
+sdk_version: "5.23.3"

+# ESCP Book Analytics Space
+
+This Hugging Face Space runs the included Jupyter notebook automatically and turns the saved outputs into:
+
+- KPI cards
+- Interactive sales charts
+- Sentiment charts
+- Top-seller analysis
+- Table previews
+- A simple AI dashboard for natural-language questions
+
+## Files included
+
+- `app.py` — the Gradio application
+- `pythonanalysis.ipynb` — your uploaded analysis notebook
+- `synthetic_sales_data.csv` — sales dataset
+- `synthetic_book_reviews.csv` — reviews dataset
+- `style.css` — local styling with no background images
+- `requirements.txt` — pinned Python dependencies
+
+## Environment variables
+
+Optional variables for the AI tab:
+
+- `HF_API_KEY`
+- `MODEL_NAME`
+- `HF_PROVIDER`
+- `PAPERMILL_TIMEOUT`
+- `AUTO_RUN_ON_LOAD`
+
+## Notes
+
+The app creates notebook outputs inside:
+
+- `artifacts/py/figures`
+- `artifacts/py/tables`
+- `runs/`
+
+The app also sanitizes the notebook before execution so `!pip install ...` cells are skipped. Dependencies are handled by `requirements.txt`.
