Note: User could run cd scripts && python collect_info.py all under project directory to get system information
and paste them here directly.

• Qlib version:pyqlib==0.9.3
• Python version: python pkgs/main/win-64::python-3.10.13-he1021f5_0
• OS (Windows, Linux, MacOS): Windows
• Commit number (optional, please provide it if you are using the dev version):

Additional Notes

Start by inspecting setup.py and the contents of the wheel produced by python -m build; the report shows that the artifact contains metadata but no importable package. Reproduce the Windows installation and import qlib or import pyqlib checks, then verify that a rebuilt wheel includes the package and imports successfully.
