python - XGBoost（免费套餐）的 Amazon Sagemaker ResourceLimitExceeded 错误

问题描述

我正在尝试在免费套餐 AWS Sagemaker 中创建 XGBoost 模型。我收到以下错误：

“ResourceLimitExceeded：调用 CreateEndpoint 操作时发生错误 (ResourceLimitExceeded)：账户级服务限制 'ml.m5.xlarge for endpoint usage' 为 0 个实例，当前利用率为 0 个实例，请求增量为 1 个实例。” .

我应该使用什么正确的 train_instance_type？

这是我的代码：

# import libraries
import boto3, re, sys, math, json, os, sagemaker, urllib.request
from sagemaker import get_execution_role
import numpy as np                                
import pandas as pd                               
import matplotlib.pyplot as plt                   
from IPython.display import Image                 
from IPython.display import display               
from time import gmtime, strftime                 
from sagemaker.predictor import csv_serializer   

# Define IAM role
role = get_execution_role()
prefix = 'sagemaker/DEMO-xgboost-dm'
containers = {'us-west-2': '433757028032.dkr.ecr.us-west-2.amazonaws.com/xgboost:latest',
              'us-east-1': '811284229777.dkr.ecr.us-east-1.amazonaws.com/xgboost:latest',
              'us-east-2': '825641698319.dkr.ecr.us-east-2.amazonaws.com/xgboost:latest',
              'eu-west-1': '685385470294.dkr.ecr.eu-west-1.amazonaws.com/xgboost:latest'} # each region has its XGBoost container
my_region = boto3.session.Session().region_name # set the region of the instance

# Create an instance of the XGBoost model (an estimator), and define the model’s hyperparameters.
# Note: train_instance_type='ml.m5.large' has 0 free credits! Use one of https://aws.amazon.com/sagemaker/pricing/ 
sess = sagemaker.Session()
xgb = sagemaker.estimator.Estimator(containers[my_region],role, train_instance_count=1, train_instance_type='ml.m5.xlarge',output_path='s3://{}/{}/output'.format('my_s3_bucket', prefix),sagemaker_session=sess)
xgb.set_hyperparameters(max_depth=1,eta=0.2,gamma=4,min_child_weight=6,subsample=0.8,silent=0,objective='binary:logistic',num_round=100)
# Train the model using gradient optimization on a ml.m4.xlarge instance
# After a few minutes, you should start to see the training logs being generated.
xgb.fit({'train': s3_input_train})

在这一步，这就是我所看到的：

然后当我部署它时：

ResourceLimitExceeded: An error occurred (ResourceLimitExceeded) when calling the CreateEndpoint operation: The account-level service limit 'ml.m5.xlarge for endpoint usage' is 0 Instances, with current utilization of 0 Instances and a request delta of 1 Instances. Please contact AWS support to request an increase for this limit.

编辑：尝试ml.m4.xlarge实例：

当我使用 ml.m4.xlarge 时，我收到相同的消息“ResourceLimitExceeded：调用 CreateEndpoint 操作时发生错误 (ResourceLimitExceeded)：账户级服务限制 'ml.m4.xlarge for endpoint usage' is 0 Instances,当前利用率为 0 个实例，请求增量为 1 个实例。请联系 AWS 支持以请求增加此限制。”
