If you happen to forget the `--recursive` during `clone`, you can use the following command after `cd aiter`
```
git submodule sync && git submodule update --init --recursive

## Run operators supported by aiter

There are number of op test, you can run them with: `python3 op_tests/test_layernorm2d.py`
