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

Error:
{
"code": "AciDeploymentFailed",
"statusCode": 404,
"message": "No definition exists for Environment with Name: myenv Version: Autosave_2021-10-25T17:24:43Z_b1d066bf Reason: Container > registry 6e07ce2cc4ac4838b42d35cda8d38616.azurecr.io not found. If private link is enabled in workspace, please verify ACR is part of private > link and retry..",

}
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.
