QUESTION
I'm trying to build a Azure Devops pipeline and ran into this error during the run stage. Can you please help me solve this issue? Thank you
There was a resource authorization issue:
The pipeline is not valid. Job Build_Scoring_image: Step buildscoringimage input connectedServiceNameARM references service connection aml-workspace-connection which could not be found. The service connection does not exist or has not been authorized for use. For authorization details, refer to https://aka.ms/yamlauthz. Job Deploy_to_Staging: Step input kubernetesServiceConnection references service connection mlops-aks which could not be found. The service connection does not exist or has not been authorized for use. For authorization details, refer to https://aka.ms/yamlauthz.
I clicked 'authorize resources' next to the error and it still failed.
...ANSWER
Answered 2022-Mar-03 at 06:39We suppose that your issue is could be resolved by re-configure your service connection in Project Setting.
And your service connection would be available again in pipelines.
QUESTION
I would like to get involved in something perhaps complicated. I would like to create the following render (see image below) with React JS. However, I thought it would be prudent to begin by using position: absolute
and repositioning my divs accordingly. However, it appears to be a difficult idea at first glance, considering the number of tags I desire (floated around the main component) for the responsive aspect and the sake that moving them with some pixel will be an indefinitely task. As a result, I was wondering whether there is a plug-in or if you have any suggestions for resolving this particular aspect. Additionally, remember that if you like to respond, it is OK to do so using basic coloured square-rectangles; I am looking forward to learning how to apply such a thing not the specific design.
Today, I have the following, but it would be unmanageable to perform this for each and hope for the best during responsive resizing.
My current code:
React JS divs:
...ANSWER
Answered 2021-Dec-15 at 22:21As Ramesh mentioned in the comments, absolute positioning is needed for the list items surrounding the main div.
- Create a container div surrounding the list items and have the width and height dimensions the same as className home. This will ensure that the list items will not be affected by flexbox.
- I would remove all flex containers inside the classNames for the list items. Instead, use position: absolute in order to use right, left, bottom, and top properties. From here, you can test different values using percentages or pixels to get the placements you wish for. For more information regarding using either pixels or percentages, this article helps with clarifying this: https://www.hongkiat.com/blog/css-units/
- As for responsive resizing: Use media queries. It is also important to use the !important property as it would give more weight to the appropriate value needed based on the screen size. For more information on media queries, visit https://css-tricks.com/a-complete-guide-to-css-media-queries/
One of the list items for responsive resizing should look something like this:

QUESTION
I have an existing TFX pipeline here that I want to rewrite using the KubeFlow Pipelines SDK.
The existing pipeline is using many TFX Standard Components such as ExampleValidator
. When checking the KubeFlow SDK, I see a kfp.components.package but no existing prebuilt components like TFX provides.
Does the KubeFlow SDK have an equivalent to the TFX Standard Components?
...ANSWER
Answered 2021-Nov-09 at 06:22You don’t have to rewrite the components, there is no mapping of components of tfx in kfp, as they are not competitive tools.
With tfx you create the components and then you use an orchestrator to run them. Kubeflow pipelines is one of the orchestrators.
The tfx.orchestration.pipeline
will wrap your tfx components and create your pipeline.
We have two schedulers behind kubeflow pipelines: Argo (used by gcp) and Tekton (used by openshift). There are examples for tfx with kubeflow pipelines using tekton and tfx with kubeflow pipelines using argo in the respective repositories.
QUESTION
I am trying to create an MLOps Pipeline using Azure DevOps and Azure Databricks. From Azure DevOps, I am submitting a Databricks job to a cluster, which trains a Machine Learning Model and saves it into MLFlow Model Registry with a custom flavour (using PyFunc Custom Model).
Now after the job gets over, I want to export this MLFlow Object (with all dependencies - Conda dependencies, two model files - one .pkl
and one .h5
, the Python Class with load_context()
and predict()
functions defined so that after exporting I can import it and call predict as we do with MLFlow Models).
How do I export this entire MLFlow Model and save it as an AzureDevOps Artifact to be used in the CD phase (where I will deploy it to an AKS cluster with a custom base image)?
...ANSWER
Answered 2021-Aug-19 at 09:05Probably you needn't to use the artifacts, there is an azure devops extension (Machine Learning), it can access artifacts in the AzureML workspace, and trigger the release pipeline. You can refer to link below for the steps: https://github.com/Azure-Samples/MLOpsDatabricks/blob/master/docs/release-pipeline.md
QUESTION
I am trying to get the second last value in each row of a data frame, meaning the first job a person has had. (Job1_latest is the most recent job and people had a different number of jobs in the past and I want to get the first one). I managed to get the last value per row with the code below:
first_job <- function(x) tail(x[!is.na(x)], 1)
first_job <- apply(data, 1, first_job)
...ANSWER
Answered 2021-May-11 at 13:56You can get the value which is next to last non-NA value.
QUESTION
Using a self-deployed ClearML server with the clearml-data CLI, I would like to manage (or view) my datasets in the WebUI as shown on the ClearML webpage (https://clear.ml/mlops/clearml-feature-store/):
However, this feature does not show up in my Web UI. According to the pricing page, the feature store is not a premium feature. Do I need to configure my server in a special way to use this feature?
...ANSWER
Answered 2021-Mar-15 at 17:59Disclaimer: I'm part of the ClearML (formerly Trains) Team
I think this screenshot is taken from the premium version... The feature itself exists in the open-source version, but I "think" some of the dataset visualization capabilities are not available in the open-source self hosted version.
Nonetheless, you have a fully featured feature-store, with the ability to add your own metrics / samples for every dataset/feature version. The open-source version also includes the advanced versioning & delta based storage for datasets/features (i.e. only the change set from the parent version is stored)
QUESTION
I am trying to find when it makes sense to create your own Kubeflow MLOps platform:
- If you are Tensorflow only shop, do you still need Kubeflow? Why not TFX only? Orchestration can be done with Airflow.
- Why use Kubeflow if all you are using scikit-learn as it does not support GPU, distributed training anyways? Orchestration can be done with Airflow.
- If you are convinced to use Kubeflow, cloud providers (Azure and GCP) are delivering ML pipeline concept (Google is using Kubeflow under the hood) as managed services. When it makes sense to deploy your own Kubeflow environment then? Even if you have a requirement to deploy on-prem, you have the option to use the cloud resources (nodes and data on cloud) to train your models, and only deploy the model to on-prem. Thus, using Azure or GCP AI Platform as managed service makes the most sense to deliver ML pipelines?
ANSWER
Answered 2020-Apr-25 at 17:37Building an MLOps platform is an action companies take in order to accelerate and manage the workflow of their data scientists in production. This workflow is reflected in ML pipelines, and includes the 3 main tasks of feature engineering
, training
and serving
.
Feature engineering and model training are tasks which require a pipeline orchestrator, as they have dependencies of subsequent tasks and that makes the whole pipeline prone to errors.
Software building pipelines are different from data pipelines, which are in turn different from ML pipelines.
A software CI/CD flow compiles the code to deploy-able artifacts and accelerates the software delivery process. So, code in, artifact out. It's being achieved by the invocation of compilation tasks, execution of tests and deployment of the artifact. Dominant orchestrators for such pipelines are Jenkins, Gitlab-CI, etc.
A data processing flow gets raw data and performs transformation to create features, aggregations, counts, etc. So data in, data out. This is achieved by the invokation of remote distributed tasks, which perform data transformations by storing intermediate artifacts in data repositories. Tools for such pipelines are Airflow, Luigi and some hadoop ecosystem solutions.
In the machine learning flow, the ML engineer writes code to train models, uses the data to evaluate them and then observes how they perform in production in order to improve them. So code and data in, model out. Hence the implementation of such a workflow requires a combination of the orchestration technologies we've discussed above.
TFX present this pipeline and proposes the use of components that perform these subsequent tasks. It defines a modern, complete ML pipeline, from building the features, to running the training, evaluating the results, deploying and serving the model in production
Kubernetes is the most advanced system for orchestrating containers, the defacto tool to run workloads in production, the cloud-agnostic solution to save you from a cloud vendor lock-in and hence optimize your costs.
Kubeflow is positioned as the way to do ML in Kubernetes, by implementing TFX. Eventually it handling the code and data in, model out. It provides a coding environment by implementing jupyter notebooks in the form of kubernetes resources, called notebooks
. All cloud providers are onboard with the project and implement their data loading mechanisms across KF's components. The orchestration is implemented via KF pipelines and the serving of the model via KF serving. The metadata across its components are specified in the specs of the kubernetes resources throughout the platform.
In Kubeflow, the TFX components exist in the form of reusable tasks, implemented as containers. The management of the lifecycle of these components is achieved through Argo, the orchestrator of KF pipelines. Argo implements these workflows as kubernetes CRDs. In a workflow
spec we define the dag tasks, the TFX components as containers, the metadata which will be written in the metadata store, etc. The execution of these workflows is happening nicely using standard kubernetes resources like pods, as well as custom resource definitions like experiments
. That makes the implementation of the pipeline and the components language-agnostic, unline Airflow which implements the tasks in python only. These tasks and their lifecycle is then managed natively by kubernetes, without the need to use duct-tape solutions like Airflow's kubernetes-operator. Since everything is implemented as kubernetes resources, everything is a yaml and so the most Git friendly configuration you can find. Good luck trying to enforce version control in Airflow's dag directory.
The deployment and management of the model in production is done via KF serving using the CRD of inferenceservice
. It utilizes Istio's secure access to the models via its virtualservices
, serverless resources using Knative Serving's scale-from-zero pods
, revisions
for versioning, prometheus metrics
for observability, logs
in ELK for debugging and more. Running models in production could not be more SRE friendly than that.
On the topic of splitting training/serving between cloud and on-premise, the use of kubernetes is even more important, as it abstracts the custom infrastructure implementation of each provider, and so provides a unified environment to the developer/ml engineer.
