2D  model checkpointing hangs on a ViT model
Labels: oncall: distributed

### 🐛 Describe the bug

### Issue
Running a ViT model to verify the 2D checkpointing, it hangs for long time without throwing any error.

This has been tested on Nighlies.

### Repro step

clone this branch, https://github.com/lessw2020/transformer_framework/tree/2D-checkpoint

```bash
sh run_training4.sh 

```
