### Motivation

This issue tracks the progress of addressing compatibility issues in the recently released KTransformers fine-tuning feature and supporting key new enhancements.

1. Python version compatibility: It has been found that the fine-tuning feature does not work well with Python 3.10. Users are advised to use Python ≥3.11 for better compatibility. Additionally, for the user of LLaMA-Factory+KTransformers integration，Python 3.13 (latest version) is currently unavailable, as some dependency packages in Llamafactory do not yet support it. https://github.com/kvcache-ai/ktransformers/pull/1572
2. Llamafile integration issues: KTransformers cannot fine-tune models with llamafile, with errors occurring during KT operator operation. We will debug it soon, but we still recommend AMX for the best solution.
3. AMD CPU adaptation: There is user demand for fine-tuning support on AMD CPUs to expand hardware coverage. Current efforts focus on adapting the heterogeneous scheduling logic to AMD's instruction sets.
4. Qwen-MoE model adaptation: Need to optimize fine-tuning compatibility for Qwen-MoE models, including handling their specific MoE layer structures and inference logic.

Additionally, community members have suggested related enhancements (e.g., VL model support, fine-tuning with reinforcement learning), which will be evaluated after resolving core compatibility issues. Contributions or PRs targeting the above issues are welcome!

Start by reviewing the Python compatibility work in PR #1572 and reproduce the reported fine-tuning issues with Python 3.10, llamafile operators, AMD CPUs, and Qwen-MoE models. The issue is complete only when the targeted compatibility problems are resolved and verified; the scope should be narrowed to one item before implementation.
