Do you feel comfortable sharing a concise (minimal) script that reproduces the error? :)

Yes, I will share a minimal reproducible script.

🐛 Describe the bug

When I run the training example from https://colossalai.org/zh-Hans/docs/advanced_tutorials/train_gpt_using_hybrid_parallelism with the following configuration, I encounter the following error:
TypeError: colossalai.shardformer.layer.attn.ColoAttention.attention() argument after ** must be a mapping, not Tensor

plugin = HybridParallelPlugin(
    tp_size=1,
    pp_size=1,
    sp_size=1,
    enable_all_optimization=True,
)

However, when I set enable_all_optimization to False in the configuration, the error disappears.
Therefore, it seems that the issue may be caused by a bug related to the enable_all_optimization option.

Below is the Python training script main.py that can reproduce the error:
