hamed225 / mlflow Goto Github PK

In this repo, I experiment with MLflow to:

• track machine learning experiments based on:

  • metrics
  • hyper-parameters
  • source scripts executing the run
  • code version
  • notes & comments

• compare different runs between each other

• set up a tracking server locally and on AWS

• deploy the your model using MLflow Models

To execute the code:

• Install pipenv to run a virtual environment with mlflow (it's cleaner this way)

pip install pipenv

• Clone the project

git clone [email protected]:ahmedbesbes/mlflow.git

• Install the dependencies

cd mlflow/
pipenv install .

• Start a tracking server locally

mlflow ui

• Launch the training (or whatever code that logs to MLflow)

python train.py

• Visit http://localhost:5000 to check the runs on the MLflow ui

If you're a team of developers or data scientists, you can spin up a tracking server where everyone logs his/her runs

• create an IAM user on AWS. Get its credentials, namely Access key ID and Secret access key

• with this same user, create an s3 bucket to store future artifacts: give this bucket a name. Mine is mlflow-artifact-store-demo but you cannot pick it

• Launch an EC2 instance: it doesn't have to be big. a t2.micro eligible to free tier does perfectly the job

• Configure the security group of this instance to accept inbound http traffic on port 5000

• ssh into your EC2:

  • install pip

    sudo apt update
    sudo apt install python3-pip

  • install pipenv

    sudo pip3 install pipenv
    sudo pip3 install virtualenv
    
    export PATH=$PATH:/home/[your_user]/.local/bin/

• now with pipenv, install the dependencies to run the mlflow server

  pipenv install mlflow
  pipenv install awscli
  pipenv install boto3

• on the EC2 machine, configure aws with user's crendentials so that the tracking server can have access to s3 and display the artifacts on the UI.

  enter aws configure then follow the instructions to enter the credentials

• start an mlflow server on the EC2 instance by defining the host as 0.0.0.0 and the --default-artifact-root as the S3 bucket

  mlflow server -h 0.0.0.0  \
                --default-artifact-root s3://mlflow-artifact-store-demo

• set the AWS credentials as environment variables so that the code uploads artifacts to the s3 bucket

  export AWS_ACCESS_KEY_ID=<your-aws-access-key-id>
  export AWS_SECRET_ACCESS_KEY = <your-aws-secret-access-key>

• change the tracking URI to the public dns of your EC2 machine + port 5000

  In my case the tracking URI was: http://ec2-35-180-45-108.eu-west-3.compute.amazonaws.com:5000/

Now you everything should be be good: after running the script locally you can inspect metrics on the UI that run on the remote server

By clicking on a specific run, you can see its artifacts uploaded to S3.

In fact, these artifacts are effectively on S3.
