Welcome @zengchen1024!

It looks like this is your first PR to mindspore-ai/mindarmour 🎉.

You will be prompted by a bot to use commands during the review process. Do not be afraid to follow the prompts! It is okay to experiment. Here is the bot commands documentation.

You can also check if mindspore-ai/mindarmour has its own contribution guidelines. We want to make sure your contribution gets all the attention it needs!

Thank you, and welcome to MindSpore. 😃

Hi @zengchen1024. Thanks for your PR.

I'm waiting for a mindspore-ai member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
