Thank you for making a PR, @drupol .

Interestingly, the CI fails consecutively 4 times. Do you have any clues?

Hello,

I don't think this is related to my changes... Or is it?

Edit: After scrutinizing those logs, I'm quite confident in saying that my changes are not responsible for these breakages.

I agree with you, @drupol . However, unfortunately, we cannot merge your PR when the CI complains.

Thanks @drupol and @dongjoon-hyun!

I think the CI failures are due to unstable connections to download dependencies.
