 Megatron-SWIFT训练Qwen3.5的提示：
-- 全参数训练：参考[这个例子](https://github.com/modelscope/ms-swift/tree/main/examples/models/qwen3_5/mcore_full.sh)。
 - 关于MTP训练："mcore-bridge>=1.1.0"支持了多模态MTP的训练（暂时需安装[main分支](https://github.com/modelscope/mcore-bridge/pull/14)），请安装对应版本。
 - TP 限制解除：使用 "megatron-core>=0.16" 可解除 TP 受到的 `num_query_groups` 限制。
 - CP支持："mcore-bridge>=1.1.0"支持了GDN的CP训练（暂时需安装[main分支](https://github.com/modelscope/mcore-bridge/pull/16)），此外需安装megatron-core dev分支。

 Tips for training Qwen3.5 with Megatron-SWIFT:
-
-- Full parameter training: Refer to [this example](https://github.com/modelscope/ms-swift/tree/main/examples/models/qwen3_5/mcore_full.sh).
 - Regarding MTP training: `mcore-bridge>=1.1.0` supports multimodal MTP training (currently requires installing the [main branch](https://github.com/modelscope/mcore-bridge/pull/14)). Please install the corresponding version.
 - TP Limitation Removed: Using `megatron-core>=0.16` removes the `num_query_groups` limitation on TP.
 - CP support: "mcore-bridge>=1.1.0" supports CP training for GDN (currently requires installing the [main branch](https://github.com/modelscope/mcore-bridge/pull/16)). Additionally, the megatron-core dev branch needs to be installed.
