tensorflow training just gets stuck!

Hi guys! I have a problem. I am using tensorflow object detection API and at the training stage it just stucks! I am using Leadtek RTX 2080 Ti Classic 11GB. I suppose the problem is in GPU architecture… because before I have used the same code and the same API with GTX 1080 Ti 11GD and everything was ok. Cuda version 10.0. Any suggestions how to solve the problem?
