+Author:
+
+## Overview
+
+
+
+## Interface
+
+```python
+__init__(self, model_name: str, framework: str = 'pytorch')
+```
+
+Args:
+
+- model_name:
+  - the model name for embedding
+  - supported types: str, for example 'xxx' or 'xxx'
+- framework:
+  - the framework of the model
+  - supported types: str, default is 'pytorch'
+
+```python
+__call__(self, call_arg_1: xxx)
+```
+
+Args:
+
+- call_arg_1:
+  - xxx(description about call_arg_1)
+  - supported types: xxx
+  Returns:
+
+The Operator returns a tuple Tuple[('results_1', xxx)] containing following fields:
+
+- results_1:
+  - xxx(description of results_1)
+  - data type: xxx
+  - shape: (xxx,)
