## 2. CLI Usage
```
usage:
json2onnx [-h]
--ij INPUT_JSON_PATH
-of OUTPUT_ONNX_FILE_PATH
optional arguments:
-h, --help
show this help message and exit
-ij INPUT_JSON_PATH, --input_json_path INPUT_JSON_PATH
Input JSON file path (*.json)
-of OUTPUT_ONNX_FILE_PATH, --output_onnx_file_path OUTPUT_ONNX_FILE_PATH
Output ONNX model path (*.onnx)
```
## 3. In-script Usage
```python
>>> from json2onnx import convert
>>> help(convert)
Help on function convert in module json2onnx.json2onnx:
convert(
input_json_path: Union[str, NoneType] = '',
json_dict: Union[dict, NoneType] = None,
output_onnx_file_path: Union[str, NoneType] = ''
)
Parameters
----------
input_json_path: Optional[str]
Input onnx file path.
Either input_json_path or json_dict must be specified.
Default: ''
json_dict: Optional[dict]
onnx.ModelProto.
Either input_onnx_file_path or json_dict must be specified.
json_dict If specified, ignore input_json_path and process json_dict.
output_onnx_file_path: Optional[str]
Output onnx file path. If not specified, no ONNX file is output.
Default: ''
Returns
-------
onnx_graph: onnx.ModelProto
Converted ONNX.
```
## 4. CLI Execution
```bash
$ json2onnx \
--input_json_path NonMaxSuppression.json \
--output_onnx_file_path NonMaxSuppression.onnx
```
## 5. In-script Execution
```python
from json2onnx import convert
