I have a model that was trained on a Machine Learning Compute on Azure Machine Learning Service. The registered model already lives my workspace and I would like to deploy it to a pre-existing AKS instance that I previously provisioned in my workspace. I am able to successfully configure and register the container image:
# retrieve cloud representations of the models
rf = Model(workspace=ws, name='pumps_rf')
le = Model(workspace=ws, name='pumps_le')
ohc = Model(workspace=ws, name='pumps_ohc')
print(rf); print(le); print(ohc)

myenv = CondaDependencies.create(pip_packages=package_list)
conda_yml = 'file:'+os.getcwd()+'/myenv.yml'
with open(conda_yml,"w") as f:
f.write(myenv.serialize_to_string())
Configuring and registering the image works:
# Image configuration
image_config = ContainerImage.image_configuration(execution_script='score.py',
runtime='python',
conda_file='myenv.yml',
description='Pumps Random Forest model')
# Register the image from the image configuration
# to Azure Container Registry
image = ContainerImage.create(name = Config.IMAGE_NAME,
models = [rf, le, ohc],
image_config = image_config,
workspace = ws)
Creating image

Attaching to an existing cluster also works:
# Attach the cluster to your workgroup
attach_config = AksCompute.attach_configuration(resource_group = Config.RESOURCE_GROUP,
cluster_name = Config.DEPLOY_COMPUTE)
aks_target = ComputeTarget.attach(workspace=ws,

However, when I try to deploy the image to the existing cluster, it fails with a WebserviceException.

Any ideas on how to solve this issue? I am writing the code in a Databricks notebook. Also, I am able to create and deploy the cluster using Azure Portal no problem so this appears to be an issue with my code/Python SDK or the way Databricks works with AMLS.
UPDATE:
I was able to deploy my image to AKS using Azure Portal and the webservice works as expected. This means the issue lies somewhere between Databricks, the Azureml Python SDK and Machine Learning Service.
UPDATE 2:
I'm working with Microsoft to fix this issue. Will report back once we have a solution.
In my initial code, when creating the image, I was not using:
image.wait_for_creation(show_output=True)
As a consequence, I was calling CreateImage and DeployImage before the image was created which errored out. Can't believe it was that simple..
UPDATED IMAGE CREATION SNIPPET:
# Register the image from the image configuration
# to Azure Container Registry
image = ContainerImage.create(name = Config.IMAGE_NAME,
models = [rf, le, ohc],
image_config = image_config,
workspace = ws)
image.wait_for_creation(show_output=True)
From personal experience I would say that the error message you see might suggest that there is some error with the script inside the image. Such errors doesn't necessary prevent the image from being created successfully, but it might prevent the image from being used in a service. However, if you have successfully been able to deploy the image in other services, then you should be able to rule out this option.
You can follow this guide for more information on how to debug the Docker image locally, as well as finding logs and other useful information.
Agreed on Arvid's answer. Were you able to succesfully run it? You can also try and deploy it to ACI, but if the problem is in the score.py, you'd have the same issue but it's quick to try. Also, a bit more painful but if you want to debug the deployment, but you can expose port tcp 5678 on your local docker deployment and use VSCode and PTVSD to connect to it and debug step by step.

I am trying to deploy a machine learning model through an ACI (Azure Container Instances) service. I am working in Python and I followed the following code (from the official documentation : https://learn.microsoft.com/en-us/azure/machine-learning/how-to-deploy-and-where?tabs=azcli) :
The entry script file is the following (score.py):
import os
import dill
import joblib
def init():
global model
# Get the path where the deployed model can be found
model_path = os.getenv('AZUREML_MODEL_DIR')
# Load existing model
model = joblib.load('model.pkl')
# Handle request to the service
def run(data):
try:
# Pick out the text property of the JSON request
# Expected JSON details {"text": "some text to evaluate"}
data = json.loads(data)
prediction = model.predict(data['text'])
return prediction
except Exception as e:
error = str(e)
return error
And the model deployment workflow is as:
from azureml.core import Workspace
# Connect to workspace
ws = Workspace(subscription_id="my-subscription-id",
resource_group="my-ressource-group-name",
workspace_name="my-workspace-name")
from azureml.core.model import Model
model = Model.register(workspace = ws,
model_path= 'model.pkl',
model_name = 'my-model',
description = 'my-description')
from azureml.core.environment import Environment
# Name environment and call requirements file
# requirements: numpy, tensorflow
myenv = Environment.from_pip_requirements(name = 'myenv', file_path = 'requirements.txt')
from azureml.core.model import InferenceConfig
# Create inference configuration
inference_config = InferenceConfig(environment=myenv, entry_script='score.py')
from azureml.core.webservice import AciWebservice #AksWebservice
# Set the virtual machine capabilities
deployment_config = AciWebservice.deploy_configuration(cpu_cores = 0.5, memory_gb = 3)
from azureml.core.model import Model
# Deploy ML model (Azure Container Instances)
service = Model.deploy(workspace=ws,
name='my-service-name',
models=[model],
inference_config=inference_config,
deployment_config=deployment_config)
service.wait_for_deployment(show_output = True)
I succeded once with the previous code. I noticed that during the deployment the Model.deploy created a container registry with a specific name (6e07ce2cc4ac4838b42d35cda8d38616).
The problem:
The API was working well and I wanted to deploy an other model from scratch. I deleted the API service and model from Azure ML Studio and the container registry from Azure ressources.
Unfortunately I am not able to deploy again anything.
Everything goes fine until the last step (the Model.deploy step), I have the following error message :
Service deployment polling reached non-successful terminal state, current service state: Unhealthy
Operation ID: 46243f9b-3833-4650-8d47-3ac54a39dc5e

}
I do not understand why the first time a new container registry was well created, but now it seems that it is sought (the message is saying that container registry identified by name 6e07ce2cc4ac4838b42d35cda8d38616 is missing). I never found where I can force the creation of a new container registry ressource in Python, neither specify a name for it in AciWebservice.deploy_configuration or Model.deploy.
Does anyone could help me moving on with this? The best solution would be I think to delete totally this 6e07ce2cc4ac4838b42d35cda8d38616 container registry but I can't find where the reference is set so Model.deploy always fall to find it.
An other solution would be to force Model.deploy to generate a new container registry, but I could find how to make that.
It's been 2 days that I am on this and I really need your help !
PS : I am not at all a DEVOPS/MLOPS guy, I make data science and good models, but infrastructure and deployment is not really my thing so please be gentle on this part ! :-)
What I tried
Creating the container registry with same name
I tried to create the container registry by hand, but this time, this is the container that cannot be created. The Python output of the Model.deploy is the following :
Tips: You can try get_logs(): https://aka.ms/debugimage#dockerlog or local deployment: https://aka.ms/debugimage#debug-locally to debug if deployment takes longer than 10 minutes.

Setting admin user enabled
I tried to follow the recommandation of the last message saying to set Admin user enabled for the container registry. All what I saw in Azure interface is that a username and password appeared when enabling on user admin.
Unfortunately the same error message appears again if I try to relaunche my code and I am stucked here...
Changing name of the environment and model
This does not produces any change. Same errors.
As you tried with first attempt it was worked. After deleting the API service and model from Azure ML Studio and the container registry from Azure resources you are not able to redeploy again.
My assumption is your first attempt you are already register the Model Environment variable. So when you try to reregister by using the same model name while deploying it will gives you the error.
Thanks # anders swanson Your solution worked for me.
If you have already registered your env, myenv, and none of the details of the your environment have changed, there is no need re-register it with myenv.register(). You can simply get the already register env using Environment.get() like so:
myenv = Environment.get(ws, name='myenv', version=11)
My Suggestion is to name your environment as new value.
"model_scoring_env". Register it once, then pass it to the InferenceConfig.

**I have deployed model endpoint in aci way back 1 month , now i want to change few thing in entry script for same model , so how i can do that without changing the restendpoint .?
My Entry script looks like below :**
SENTIMENT_THRESHOLDS = (0.4, 0.7)
SEQUENCE_LENGTH = 300
def run(data):
try:
# Pick out the text property of the JSON request.
# This expects a request in the form of {"text": "some text to score for sentiment"}
data = json.loads(data)
prediction = predict(data['text'])
#Return prediction
return prediction
except Exception as e:
error = str(e)
return error
**Now i want to change the variable SEQUENCE_LENGTH and update the restendpoint with this entry script file **
To re-deploy to ACI is use the :latest tag on your Docker image in the registry. If you re-deploy the image to the registry and re-start ACI to the pointer registry it will auto-deploy the new version/image.
And if you are simply trying to debug and redeploy, doing so locally Please follow the below doc.
https://learn.microsoft.com/en-us/azure/machine-learning/how-to-troubleshoot-deployment#debug-locally
Doc to update the deployed web service using the SDK.
I have a KubeFlow Pipeline up and running on a VM in GCP with KF.
I create the pipeline using a Jupyter Notebook server with image jupyter-kale and python.
The first part of the pipeline is doing the dataprep, it downloads images and saves them to a PVC. This all works just fine but I run out of storage space so I decided to save the images downloaded directly to a google Bucket instead using the PVC.
I modified my pipeline as shown in the code below:
import kfp
import kfp.dsl as dsl
import kfp.onprem as onprem
import kfp.compiler as compiler
import os
#dsl.pipeline(
name='try_mount',
description='...'
)
def one_d_pipe(pvc_name = "gs://xxx-images/my_folder/"):
trymount = dsl.ContainerOp(
name="trymount",
#image = "sprintname3:0.2.0",
image = "eu.gcr.io/xxx-admin/kubeflow/trymount_1:0.1"
)
steps = [trymount]
for step in steps:
step.apply(onprem.mount_pvc(pvc_name, "gs://xxx-images/my_folder/", '/home/jovyan/data'))
But this code resulting in an error message right after start saying that the volume has invalid value and could not be found:
This step is in Error state with this message: Pod "try-mount-75vrt-3151677017" is invalid: [spec.volumes[2].name: Invalid value: "gs://xxx-images/my_folder/": a DNS-1123 label must consist of lower case alphanumeric characters or '-', and must start and end with an alphanumeric character (e.g. 'my-name', or '123-abc', regex used for validation is 'a-z0-9?'), spec.containers[0].volumeMounts[3].name: Not found: "gs://xxx-images/my_folder/", spec.containers[1].volumeMounts[0].name: Not found: "gs://xxx-images/my_folder/"]
So, my question:
How to mount a google bucket in Kubeflow Pipelines?
You can't mount a bucket as a volume. It's not a file system. However, I'm sure that you can cheat by use gcsfuse on your VM.
On your VM, mount the GCS bucket with fuse
gcsfuse xxx-images /path/to/mount-gcs
Then in your code, use this directory. No mount required, the GCS is already mount with GCSFuse.
I have been able to successfully host a model using the image config method
service = Webservice.deploy_from_model(workspace=ws,
name='name_of_model',
deployment_config=aciconfig,
models=[model],
image_config=image_config)
However this method is to be deprecated with the Environment Method
Hence I attempted using the Environment method suggested below in the deprecation message. But I always get a timeout . It never deploys successfully like the old container method
How to Use Environments - Microsoft Azure ML
My Environment based deployment code
My code is below with the inference_config pointing out to the score.py and deployment_config pointing to the specs of the container. I can see that the service gets created and the model being uploaded . But the service never goes to "Healthy" state. However the same code in the container deployment model works fine .
service = Model.deploy(
workspace = ws,
name = "name_of_model",
models = [model],
inference_config = inference_config,
deployment_config = deployment_config)
My env configuration from an existing environment provided by Azure ML
my_env=Environment.get(workspace=ws,name='AzureML-Scikit-learn-0.20.3') # using Azure Optimized sklearn environment
This env being referenced in the inference config
inference_config = InferenceConfig(entry_script="scorev3.py", environment=my_env) # using the initialized variable my_env
Any clue as to why I'm having a time-out when deploying this ?. I certainly feel its not to do with the internet connection as the old method takes similar long time (10-12 minutes) to deploy and goes through perfect ?
I was trying to register an ONNX model to Azure Machine Learning service workspace in two different ways, but I am getting errors I couldn't solve.
First method: Via Jupyter Notebook and python Script
model = Model.register(model_path = MODEL_FILENAME,
model_name = "MyONNXmodel",
tags = {"onnx":"V0"},
description = "test",
workspace = ws)
The error is : HttpOperationError: Operation returned an invalid status code 'Service invocation failed!Request: GET https://cert-westeurope.experiments.azureml.net/rp/workspaces'
Second method: Via Azure Portal
Anyone can help please?
error 413 means the payload is too large. Using Azure portal, you can only upload a model upto 25MB in size. Please use python SDK to upload models larger than 25MB.
