SageMaker Studio Lab - XGBoost Algortim - Am I Reading the Right Documentation? - xgboost

Question

Google has answers for SageMaker Studio, but I am at a loss for an answer on SageMaker Studio LAB...
I am reading the following on XGBoost - Am I in the right place for SM Studio LAB?
https://docs.aws.amazon.com/sagemaker/latest/dg/xgboost.html
Is there a better way for me to use XGBoost in LAB, vs what I am doing below by reading the doc above?
In SageMaker Studio I would do the following to get the ECR container for the XGBoost algorithm:
from sagemaker import image_uris
container = image_uris.retrieve('xgboost', boto3.Session().region_name, '1')
I made it a bit farther using the github example:
https://github.com/aws/studio-lab-examples/blob/main/connect-to-aws/Access_AWS_from_Studio_Lab.ipynb
This works:
from sagemaker import image_uris
from sagemaker.xgboost import XGBoost
# Create a training job name
job_name = 'ufo-xgboost-job-{}'.format(datetime.now().strftime("%Y%m%d%H%M%S"))
print('Here is the job name {}'.format(job_name))
import sagemaker
import boto3
from sagemaker import image_uris
from sagemaker.session import Session
from sagemaker.inputs import TrainingInput
But this is giving me trouble:
sess = sagemaker.Session()
xgb = sagemaker.estimator.Estimator(container,
role,
instance_count=1,
instance_type='ml.m4.xlarge',
output_path='model.tar.gz',
sagemaker_session=sess)
xgb.set_hyperparameters(objective='multi:softmax',
num_class=3,
num_round=100)
data_channels = {
'train': s3_input_train,
'validation': s3_input_validation
}
xgb.fit(data_channels, job_name=job_name)

You're trying to run an external training job that would run outside of your Studio Lab Environment, on an ephemeral EC2 instance as part of a SageMaker training job.
With the error being: ConfigParseError: Unable to parse config file: /home/studio-lab-user/.aws/config it sounds like you didn't configure your AWS credentials correctly.
Did you complete successfully step 0 and step 1, in this guide for connecting Studio Lab with your AWS account?
Alternatively: Run XGBoost locally in your Studio Lab - OR - as you already have an AWS account use SageMaker Studio (isn't free), which will already be configured with a certain IAM role your admin will configure when creating the Studio domain.
