Note
Sentis is now called Inference Engine. The documentation has moved to https://docs.unity3d.com/Packages/com.unity.ai.inference@latest. Refer to the new location for the latest updates and guidance. Make sure to update your bookmarks and references accordingly.
Model Asset Import Settings
The Model Asset Import Settings window lets you do the following:
- Serialize the model to the
StreamingAssetsfolder. - Check the properties of an imported and optimized model.
To access this window, select an imported model asset in the Project window.

Inputs
The table below shows both the total count of inputs that the model possesses and provides a list detailing these inputs.
| Property | Description |
|---|---|
| name | The name of the input. |
| index | The index of the input. |
| shape | The tensor shape of the input. For example (1, 1, 28, 28) means the model accepts a tensor of size 1 × 1 × 28 × 28 exactly. If a dimension in the shape is a string instead of a number, for example ?, d0 or d1, the dimension can be any size (a dynamic input). Refer to Model inputs for more information about dynamic inputs. |
| dataType | The data type of the input. |
Outputs
The table below shows both the total count of outputs that the model possesses and provides a list detailing these outputs.
| Property | Description |
|---|---|
| name | The name of the output. |
| index | The index of the output. |
| shape | The tensor shape of the output. Sentis tries to precalculate this shape from the model. If a dimension in the shape is a question mark (?), Sentis can't calculate the size of the dimension, or the size depends on the input (a dynamic output). If the entire tensor shape is Unknown, Sentis can't calculate the number of dimensions, or the number of dimensions is dynamic. |
| dataType | The data type of the output. |
Layers
The table below shows the overall count of layers the model possesses along with a list of layers detailing the order in which Sentis executes them.
| Property | Description |
|---|---|
| type | The type of layer. Refer to Supported ONNX operators for more information. |
| index | The index of the layer. |
| inputs | The names of the inputs to the layer. Possible values are a model input from the Inputs section, another layer, or a constant. |
| properties | The properties of the layer. The properties will depend on the type of layer. Refer to Supported ONNX operators for more information. |
Constants
The table below shows the total count of constants and weights that the model possesses along with a list detailing the constants.
| Property | Description |
|---|---|
| type | The type is always Constant. |
| index | The index of the constant. |
| weights | The tensor shape of the constant. If the tensor shape is empty - () - the constant is a scalar (a zero-dimensional tensor). |
Model information
This section shows the model's total size, the ONNX opset version, and the tool used to create the model file.
