Model URI Structure
SavedModel Format*
We support TensorFlow2 SavedModel format. The model uri structure is just the output of tf.saved_model.save()
.
<model uri>
├── saved_model.pb
└── variables
├── variables.data-00000-of-00001
└── variables.index
HDF5 Format
We also support HDF5 format which is saved from Keras API in both TensorFlow 2
and TensorFlow 1
.
<model uri>
└── model.h5
- model.h5: The file is HDF5 format, and can be any file name with
.h5
file extension.
How It Works
You can check the detailed code in the Github. Here, we brief the code as follows.
Load the model
def load(self):
model_uri = self.model_uri
self.use_keras_api = 1
if tf.saved_model.contains_saved_model(model_uri):
self.model = tf.saved_model.load(model_uri).signatures["serving_default"]
if 'saved_model' not in str(type(self.model)):
self.use_keras_api = 0
else:
del self.model
if self.use_keras_api:
if not glob.glob(os.path.join(model_uri, '*.h5')):
self.model = tf.keras.models.load_model(model_uri)
else:
self.model = tf.keras.models.load_model(glob.glob(os.path.join(model_uri, '*.h5'))[0])
self.loaded = True
print(f"Use Keras API: {self.use_keras_api}")
print(f"Model input layer: {self.model.inputs[0]}")
Predict
def predict(self, X):
if not self.loaded:
self.load()
if self.use_keras_api:
return self.model.predict(X)
else:
output = self.model(tf.convert_to_tensor(X, self.model.inputs[0].dtype))
return output[next(iter(output))].numpy()
Example
The example uses the Keras MNIST dataset, which is used in tensorflow tutorial.
