WSL Ubuntu

Additional Notes

[Hoder-zyf]

what's your model? Deepseek?

[Tylor-Tian]

I use openai

[Tylor-Tian]

I change max_retry = 100 and it is still does not work

[Hoder-zyf]

Maybe you can switch branch to qlib_ds and try again.
It seems that hypothesis doesn't return a string and I have enhanced this string section in that branch though because the observation of deepseek failure. BUT I think you can switch to that branch and have a try.

[Hoder-zyf]

Now you can pull our latest main branch and have a try. If you have any questions, just comment here.
