Clienterror: An error occured when calling the CreateModel operation

I want to deploy sklearn model in sagemaker. I created a training script.

scripPath=' sklearn.py'

sklearn=SKLearn(entry_point=scripPath, train_instance_type='ml.m5.xlarge', role=role, output_path='s3://{}/{}/output'.format(bucket,prefix), sagemaker_session=session) sklearn.fit({"train-dir' : train_input})

When I deploy it predictor=sklearn.deploy(initial_count=1,instance_type='ml.m5.xlarge')

It throws, Clienterror: An error occured when calling the CreateModel operation:Could not find model data at s3://tree/sklearn/output/model.tar.gz

Can anyone say how to solve this issue?

When deploying models, SageMaker looks up S3 to find your trained model artifact. It seems that there is no trained model artifact at s3://tree/sklearn/output/model.tar.gz. Make sure to persist your model artifact in your training script at the appropriate local location in docker which is /opt/ml/model. for example, in your training script this could look like:

joblib.dump(model, /opt/ml/model/mymodel.joblib)

After training, SageMaker will copy the content of /opt/ml/model to s3 at the output_path location.

If you deploy in the same session a model.deploy() will map automatically to the artifact path. If you want to deploy a model that you trained elsewhere, possibly during a different session or in a different hardware, you need to explicitly instantiate a model before deploying

from sagemaker.sklearn.model import SKLearnModel

model = SKLearnModel(
    model_data='s3://...model.tar.gz',  # your artifact
    role=get_execution_role(),
    entry_point='script.py')  # script containing inference functions

model.deploy(
    instance_type='ml.m5.xlarge',
    initial_instance_count=1,
    endpoint_name='your_endpoint_name')
