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