使用“paws”包访问 AWS Rekognition 面部分析时遇到问题
Trouble accessing AWS Rekognition facial analysis using ``paws`` package
这不是数据分析问题，所以我没有数据可以重现。
我安装了来自 this Github page 的 paws 软件包，以通过 Amazon Rekognition 提取面部特征（即微笑）。我将其作为研究的一部分来测试 Microsoft Azure 和 Face++ 的性能。顺便说一下，我用适当的安全 ID 替换了 "AccessKeyHere" 和 "SecretKeyHere"。
library(paws)
Sys.setenv(
AWS_ACCESS_KEY_ID = "AccessKeyHere",
AWS_SECRET_ACCESS_KEY = "SecretKeyHere",
AWS_REGION = "us-east-1"
)
ec2 <- paws::ec2()
resp <- ec2$run_instances(
ImageId = "ami-f973ab84",
InstanceType = "t2.micro",
KeyName = "default",
MinCount = 1,
MaxCount = 1,
TagSpecifications = list(
list(
ResourceType = "instance",
Tags = list(
list(Key = "webserver", Value = "production")
)
)
)
)
不幸的是，我得到这个错误：
Error: InvalidKeyPair.NotFound: The key pair 'default' does not exist
我尝试按照 Github page 中的 设置凭据 文档进行操作，但没有成功。
我想要的结果看起来像这样（直接取自亚马逊演示）：

要是能晋级到这一步就好了。但如果提取的数据看起来与我的 Microsoft Azure 结果一致，那就更好了：

错误与此行有关：
KeyName = "default",
它指的是应该附加到 Amazon EC2 实例的 Amazon EC2 Key Pair。但是，没有名为 default 的密钥对。因此，它失败了。
要修复它，您应该使用已创建的密钥对的名称而不是 default。您可以在 EC2 管理控制台中看到密钥对列表。您也可以删除此行（不指定 KeyName），但那样您将无法登录实例。
这不是数据分析问题，所以我没有数据可以重现。
