Review comment:
What about changed it as following:
```
origin_execution_mode = os.environ['_python_worker_execution_mode']
os.environ['_python_worker_execution_mode'] = "loopback"
try:
self.st_env =
TableEnvironment.create(EnvironmentSettings.in_streaming_mode())
finally:
if origin_execution_mode is not None:
os.environ['_python_worker_execution_mode'] = origin_execution_mode
```
