Issue #, if available:
XGBoost-1.7 introduced a braking change that introduced issue with NCCL. To address the issue, we need to set the NCCL_SOCKET_IFNAME env. variable
Description of changes:
set NCCL_SOCKET_IFNAME
Testing:
Created a test image: 900597767885.dkr.ecr.us-west-2.amazonaws.com/sagemaker-xgboost:nikhil-test
And tested the image, it is not throwing an error anymore for binary classification. (arn:aws:sagemaker:us-west-2:900597767885:training-job/sagemaker-xgboost-2023-03-17-14-36-52-062)
