To Reproduce

Steps to reproduce the behavior:

1.cd examples # Avoid running program under the directory contains qlib
2.qrun benchmarks/LightGBM/workflow_config_lightgbm_Alpha158.yaml

Environment

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: Newest
• Python version: 3.8.5
• OS (MacOS):
• Commit number (optional, please provide it if you are using the dev version):

Additional Notes

Please help, thanks a lot!~

Reproduce the failure from the examples directory with qrun benchmarks/LightGBM/workflow_config_lightgbm_Alpha158.yaml. Review that workflow configuration and run scripts/collect_info.py all to capture the missing environment details, then narrow down the stage causing the segmentation fault. Done means the workflow completes without the crash on the reported macOS setup.
