Request for Release Update on `Fix for RuntimeError('context has already been set')`

Hello,

I'm encountering the `RuntimeError('context has already been set')` error on both macOS and Ubuntu environments. I noticed that this issue seems to have been addressed in [Pull Request #223](https://github.com/guofei9987/scikit-opt/pull/223), but the issue still appears in the latest release version `scikit-opt==0.6.6`. Is there a planned timeline for releasing the latest code to PyPI?

This package has been incredibly helpful for my project, and a new release would be much appreciated. Thank you, and I look forward to your response.

Review Pull Request #223 and compare its fix with the PyPI package version scikit-opt==0.6.6. Confirm whether the fix is included; done means releasing the updated code to PyPI so the RuntimeError no longer affects users of the latest release.
