Hey, this is the MXNet Label Bot.
Thank you for submitting the issue! I will try and suggest some labels so that the appropriate MXNet community members can help resolve it.
Here are my recommended labels: Test, Flaky

@mxnet-label-bot add [Test, Flaky]

Based on the master branch CI log, the test started to become flaky after #14136 is merged.

The test I added (test_dataloader_context) in #14136 is not part of GPU CI. I do not see how it causes the flakiness for the test mentioned here.
