One of the highlighted features with regard to the new API is __shape inference__. Users only need to specify the input shape (a `Shape` object __excluding__ batch dimension, for example, `inputShape=Shape(3, 4)` for 3D input) for the first layer of a model and for the remaining layers, the input dimension will be automatically inferred.

## 8. Persistence
This section describes how to save and load the Keras-like API.
### 8.1 save
To save a Keras model, you call the method `saveModel(path)`.
**Scala:**
```scala
import com.intel.analytics.bigdl.dllib.keras.layers.{Dense, Activation}
import com.intel.analytics.bigdl.dllib.keras.models.Sequential
val model = Sequential[Float]()
model.add(Dense[Float](32, inputShape = Shape(128)))
model.add(Activation[Float]("relu"))
model.saveModel("/tmp/seq.model")
```
**Python:**
```python
import bigdl.dllib.keras.Sequential
from bigdl.dllib.keras.layer import Dense
model = Sequential()
model.add(Dense(input_shape=(32, )))
model.saveModel("/tmp/seq.model")
```
### 8.2 load
To load a saved Keras model, you call the method `load_model(path)`.
**Scala:**
```scala
import com.intel.analytics.bigdl.dllib.keras.Models
val model = Models.loadModel[Float]("/tmp/seq.model")
```
**Python:**
```python
from bigdl.dllib.keras.models
model = load_model("/tmp/seq.model")
```
