[BUG]: RuntimeError(f"Could not compute metadata for {kind} target {target}: {e}")

Start with colossalai/fx/tracer/tracer.py, especially _meta_data_computing and create_proxy, and compare the failing get_attr path with the installed PyTorch FX behavior shown in the traceback. A minimal reproduction and environment details are still needed; done means metadata computation succeeds for the reported transformer target or the incompatibility is documented with a confirmed fix path.

Is there an existing issue for this bug?

• I have searched the existing issues

The bug has not been fixed in the latest main branch

• I have checked the latest main branch

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

Yes, I will share a minimal reproducible script.

🐛 Describe the bug

Is it because the PyTorch version is not right?
