[GitHub] [tvm] driazati opened a new issue #10297: [CI Problem] `tests/micro/zephyr/test_zephyr.py::test_autotune_conv2d` is flaky
driazati opened a new issue #10297:
URL: https://github.com/apache/tvm/issues/10297
See [tests/micro/zephyr/test_zephyr.py::test_autotune_conv2d](https://ci.tlcpack.ai/blue/organizations/jenkins/tvm/detail/PR-10292/1/pipeline/61), pytest also segfaulted out which is weird
