Problem of lightprobe

I loaded scenes from assetbundle, but got no lightprobe of it.
I used Assetbundle.CreateFromFile(), and UnityEngine.SceneManagement.SceneManager.LoadScene(). In the scene gameobject start(), I tested lightprobe by LightmapSettings.lightProbes, I got null, and no meshrenderer using lightprobe illuminated by probes.
My Unity version is 5.3.4.
