我试图将类型从Float64转换为Float32的阈值数组(隔离森林的pickle文件从scikit学习)

for i in range(len(tree.tree_.threshold)):
    tree.tree_.threshold[i] = tree.tree_.threshold[i].astype(np.float32)

然后打印它

for value in tree.tree_.threshold[:5]:
    print(type(value))
    print(value)

我得到的输出是:

<class 'numpy.float64'>
526226.0
<class 'numpy.float64'>
91.9514312744
<class 'numpy.float64'>
3.60330319405
<class 'numpy.float64'>
-2.0
<class 'numpy.float64'>
-2.0

我没有得到正确的转换到Float32.我想将值及其类型转换为Float32,有没有人有解决方法？

我正在尝试从AMI创建Windows Ec2实例，并在该实例上执行powershell命令：

data "aws_ami" "ec2-worker-initial-encrypted-ami" {
    filter {
        name   = "tag:Name"
        values = ["ec2-worker-initial-encrypted-ami"]
    }  
}

resource "aws_instance" "my-test-instance" {
  ami             = "${data.aws_ami.ec2-worker-initial-encrypted-ami.id}"
  instance_type   = "t2.micro"

  tags {
    Name = "my-test-instance"
  }

  provisioner "local-exec" {
    command = "C:\\ProgramData\\Amazon\\EC2-Windows\\Launch\\Scripts\\InitializeInstance.ps1 -Schedule",
    interpreter = ["PowerShell"]
  }

}

而且我面临以下错误：

• aws_instance.my-test-instance：运行命令'C：\ ProgramData \ Amazon \ EC2-Windows \ Launch \ Scripts \ InitializeInstance.ps1 -Schedule'时出错：退出状态1.输出：术语'C：\ ProgramData \ Amazon \ EC2-Windows \ Launch \ Scripts \ InitializeInstance.ps1'无法识别为cmdlet，函数，脚本文件或可运行程序的名称。检查名称的拼写，或者是否包含路径，请验证路径是否正确，然后重试。在线：1字符：72
