Sagemaker Model 部署错误，ClientError：调用 CreateModel 操作时发生错误（ValidationException）

Question

I am trying to deploy a model with AWS Sagemaker using SKlearn, and getting this error:

The code I am running is:

from sagemaker import Session, get_execution_role
from sagemaker.sklearn.estimator import SKLearn

sagemaker_session = Session()
role = get_execution_role()

train_input = sagemaker_session.upload_data("TSLA.csv")

model = SKLearn(entry_point='lr.py',
                      train_instance_type='ml.m4.xlarge',
                      role=role, framework_version='0.231',
                      sagemaker_session=sagemaker_session)

model.fit({'train': train_input})

deployment = model.deploy(initial_instance_count=1, instance_type="ml.m4.xlarge")

And train_input is: s3://sagemaker-us-east-2-978433479050/data/TSLA.csv

The training job is completed, but for some reason the model is not deploying.

Please advise, thank you

Answer 1

The logs are indicating that your trained model artifact is not being captured properly. Please run

model.data #estimator that you are training

This will show if your model artifact/data was actually created (model.tar.gz).

Here is an example of training/deploying a sklearn model: https://github.com/RamVegiraju/SageMaker-Deployment/tree/master/RealTime/Script-Mode/Sklearn/Regression
