当使用AWS Sagemaker时,出现“客户端错误:数据下载失败:无法下载”错误通常是由于以下原因引起的:
import boto3
def check_bucket_exists(bucket_name):
s3 = boto3.resource('s3')
try:
s3.meta.client.head_bucket(Bucket=bucket_name)
return True
except Exception as e:
return False
bucket_name = 'your_bucket_name'
if check_bucket_exists(bucket_name):
print(f'Bucket {bucket_name} exists')
else:
print(f'Bucket {bucket_name} does not exist')
import boto3
def check_file_exists(bucket_name, file_path):
s3 = boto3.resource('s3')
try:
s3.Object(bucket_name, file_path).load()
return True
except Exception as e:
return False
bucket_name = 'your_bucket_name'
file_path = 'your_file_path'
if check_file_exists(bucket_name, file_path):
print(f'File {file_path} exists in bucket {bucket_name}')
else:
print(f'File {file_path} does not exist in bucket {bucket_name}')
