notebook-finetuning -- Unsloth fine-tuning notebook data candy
Candy Properties
| Property | Value |
|----------|-------|
| Dependencies | (none) |
| Packages | (none) |
| Services | (none) |
| Volumes | workspace -> /workspace (from unsloth-studio) |
| Data | data/finetuning -> workspace volume, dest: finetuning |
| Install files | (none) |
How It Works
This is a data candy — it uses the data: field in charly.yml to map a directory of notebooks to a named volume with a subdirectory destination:
info: "Unsloth fine-tuning notebook collection for unsloth-studio"
data:
- src: data/finetuning
volume: workspace
dest: finetuning
At build time, the contents of data/finetuning/ are staged into /data/workspace/finetuning/ inside the box.
At deploy time, when the workspace volume is configured as a bind mount (charly config --bind workspace), charly config copies the staged data into the host-backed volume directory at <workspace>/finetuning/. This seeds the volume with ready-to-use training notebooks.
The dest: finetuning field places the notebooks in a subdirectory rather than the volume root, keeping the workspace organized alongside other content.
Included Data
37 Jupyter notebooks + 1 manifest, organized by training category:
| Category | Notebooks | Models |
|----------|-----------|--------|
| 00-Setup | 00_Unsloth_Setup.ipynb | (general) |
| 01-FastInference | 3 notebooks | Llama, Qwen, Qwen_Think |
| 02-Vision Training | 2 notebooks | Ministral, Pixtral |
| 03-SFT Training | 5 notebooks | Ministral (text + vision), Pixtral, Qwen, Qwen_Think |
| 04-GRPO Training | 5 notebooks | Ministral (text + vision), Pixtral, Qwen, Qwen_Think |
| 05-DPO Training | 2 notebooks | Qwen, Qwen_Think |
| 06-Reward Training | 2 notebooks | Qwen, Qwen_Think |
| 07-RLOO Training | 5 notebooks | Ministral (text + vision), Pixtral, Qwen, Qwen_Think |
| 08-QLoRA | 12 notebooks | Ministral, Qwen_Think (alpha scaling, continual learning, rank comparison, multi-adapter, quantization comparison, target modules) |
Manifest: notebooks.yaml — structured catalog of all notebooks with metadata.
Usage
# charly.yml
unsloth-studio:
candy:
- unsloth-studio
- notebook-finetuning
# ... other candies
# Deploy with bind-backed workspace volume
charly config unsloth-studio --bind workspace
# Notebooks are seeded at <workspace>/finetuning/ on first config
charly start unsloth-studio
# Open http://localhost:8888 → navigate to finetuning/
Notebook Compatibility Fixes
The notebooks include several workarounds for upstream library changes:
packing=Truein SFTConfig (19 notebooks) -- Required for TRL 1.0 compatibility. Without it, SFT training fails with the updated TRL APIos.environ["UNSLOTH_ENABLE_FLEX_ATTENTION"] = "0"(16 Ministral/Pixtral notebooks) -- Disables flex_attention to work around a transformers 5.5 bug that crashes these model architecturesmax_memory={0: "14GB"}in model loading (3 Pixtral-12B notebooks) -- Fixes accelerate device_map estimation for Pixtral-12B models that would otherwise OOMmax_prompt_lengthremoved from DPOConfig (2 DPO notebooks) -- Parameter deprecated and removed in TRL 1.0

When to Use This Skill
Use when the user asks about:
- The notebook-finetuning candy or its contents
- Unsloth fine-tuning notebook templates or training workflows
- How training notebooks get provisioned into the workspace volume
- The
data:field withdest:subdirectory mapping - Which models and training methods are covered by the notebook collection
