+ # gradio_dataset_manager.py – Unified YOLO Dataset Toolkit (EvaluateΒ +Β Merge/Edit)
2
+ """
3
+ Gradio application that **combines** the functionality of the original evaluation‑only app and
4
+ the Streamlit dataset‑merging dashboard.
5
+
6
+ ### Key features added
7
+ * **Multi‑dataset loader**
8
+ – Roboflow URLs (with automatic latest‑version fallback)
9
+ – ZIP uploads (GitHub/Ultralytics releases, etc.)
10
+ – Existing server paths
11
+ * **Interactive class manager** (rename / remove / per‑class max images) using an **editable
12
+ Gradio `Dataframe`**. Multiple rows can share the same *NewΒ name* to merge classes.
13
+ * **Dataset merger** with:
14
+ – Per‑class image limits
15
+ – Consistent re‑indexing after renames/removals
16
+ – Duplicate image avoidance
17
+ – Final `data.yaml` + ready‑to‑train directory structure
18
+ * One‑click **ZIP download** of the merged dataset
19
+ * Original **Quality Evaluation** preserved (blur/IOU/conf sliders, fastdup, optional
20
+ Model‑QA/Cleanlab)
21
+
22
+ > ⚠️ This is a standalone Python script – drop it into a HuggingΒ Face **Space** or run with
23
+ > `python gradio_dataset_manager.py`. Requires the same pip deps you already list.
