--- BEGIN ISSUE ---
[Test] Fix lightgbm test in new test-infra
During the process I helped kfserving migrate to new test-infra, noticed that lightgbm failed every time, and to mitigate the issue, I disabled it in the pytest.

I'm working on the lightgbm test cases, and see if I can reproduce locally. 

Need to spend time and dig into it 

Detailed can be found https://github.com/kubeflow/kfserving/pull/1329#issuecomment-770325947
