Serve SKLearn Iris Model¶
In order to deploy SKLearn artifacts, we can leverage the pre-packaged SKLearn inference server. The exposed API can follow either:
The default Seldon protocol.
The V2 protocol.
Default Seldon protocol¶
To deploy and start serving an SKLearn artifact using Seldon’s default protocol, we can use a config like the one below:
[2]:
%%writefile ../servers/sklearnserver/samples/iris.yaml
apiVersion: machinelearning.seldon.io/v1alpha2
kind: SeldonDeployment
metadata:
name: sklearn
spec:
predictors:
- graph:
name: classifier
implementation: SKLEARN_SERVER
modelUri: gs://seldon-models/v1.16.0-dev/sklearn/iris
name: default
replicas: 1
svcOrchSpec:
env:
- name: SELDON_LOG_LEVEL
value: DEBUG
Overwriting ../servers/sklearnserver/samples/iris.yaml
We can then apply it to deploy it to our Kubernetes cluster.
[3]:
!kubectl apply -f ../servers/sklearnserver/samples/iris.yaml
seldondeployment.machinelearning.seldon.io/sklearn created
[4]:
!kubectl rollout status deploy/$(kubectl get deploy -l seldon-deployment-id=sklearn -o jsonpath='{.items[0].metadata.name}')
Waiting for deployment "sklearn-default-0-classifier" rollout to finish: 0 of 1 updated replicas are available...
deployment "sklearn-default-0-classifier" successfully rolled out
Once it’s deployed we can send our sklearn model requests

And delete the model we deployed
[10]:
!kubectl delete -f ../servers/sklearnserver/samples/iris.yaml
seldondeployment.machinelearning.seldon.io "sklearn" deleted
V2 protocol¶
For example, we can consider the config below:
[11]:
%%writefile ./resources/iris-sklearn-v2.yaml
apiVersion: machinelearning.seldon.io/v1
kind: SeldonDeployment
metadata:

modelUri: gs://seldon-models/sklearn/iris-0.23.2/lr_model

Overwriting ./resources/iris-sklearn-v2.yaml
We can then apply it to deploy our model to our Kubernetes cluster.
[12]:
!kubectl apply -f resources/iris-sklearn-v2.yaml
seldondeployment.machinelearning.seldon.io/sklearn created
[13]:
!kubectl rollout status deploy/$(kubectl get deploy -l seldon-deployment-id=sklearn -o jsonpath='{.items[0].metadata.name}')

deployment "sklearn-default-0-classifier" successfully rolled out
Once it’s deployed, we can send inference requests to our model. Note that, since it’s using the V2 Protocol, these requests will be different to the ones using the default Seldon Protocol.
[20]:
import json
import requests
inference_request = {

Serve XGBoost Iris Model¶
In order to deploy XGBoost models, we can leverage the pre-packaged XGBoost inference server. The exposed API can follow either:
The default Seldon protocol.
The V2 protocol
Default Seldon protocol¶
We can deploy a XGBoost model uploaded to an object store by using the XGBoost model server implementation as shown in the config below:
[22]:
%%writefile resources/iris.yaml
apiVersion: machinelearning.seldon.io/v1
kind: SeldonDeployment
metadata:

spec:
name: iris
predictors:
- graph:
children: []
implementation: XGBOOST_SERVER

And then we apply it to deploy it to our kubernetes cluster
[23]:
!kubectl apply -f resources/iris.yaml
seldondeployment.machinelearning.seldon.io/xgboost created
[24]:
!kubectl rollout status deploy/$(kubectl get deploy -l seldon-deployment-id=xgboost -o jsonpath='{.items[0].metadata.name}')

V2 protocol¶
We can deploy a XGBoost model, exposing an API compatible with v2 protocol by specifying the protocol of our SeldonDeployment as v2. For example, we can consider the config below:
[19]:
%%writefile ./resources/iris-xgboost-v2.yaml
apiVersion: machinelearning.seldon.io/v1
kind: SeldonDeployment
metadata:
name: xgboost

implementation: XGBOOST_SERVER
modelUri: gs://seldon-models/xgboost/iris

Overwriting ./resources/iris-xgboost-v2.yaml
We can then apply it to deploy our model to our Kubernetes cluster.
[20]:
!kubectl apply -f ./resources/iris-xgboost-v2.yaml
seldondeployment.machinelearning.seldon.io/xgboost configured
[16]:
!kubectl rollout status deploy/$(kubectl get deploy -l seldon-deployment-id=xgboost -o jsonpath='{.items[0].metadata.name}')
Waiting for deployment "xgboost-default-0-classifier" rollout to finish: 0 of 1 updated replicas are available...

Once it’s deployed, we can send inference requests to our model. Note that, since it’s using the V2 Protocol, these requests will be different to the ones using the default Seldon Protocol.
[21]:
import json
import requests
inference_request = {
"inputs": [

Serve Tensorflow MNIST Model¶
We can deploy a tensorflow model uploaded to an object store by using the tensorflow model server implementation as the config below.
This notebook contains two examples, one which shows how you can use the TFServing prepackaged serve with the Seldon Protocol, and a second one which shows how you can deploy it using the tensorlfow protocol (so you can send requests of the exact format as you would to a tfserving server).
