Boto3.describe_images没有响应

Question

我正在使用boto3通过过滤器获取所有可用的Amazon AMI（公共），我在Boto3文档中找到了client.describe_images（** kwargs）。但是我无法应用过滤器。这是2个示例代码，它们试图访问1. Windows上的所有AMI，以及其他2. OpenSUSE的代码。 Boto能够获取所有Windows AMI，但不能获取OpenSUSE。我想我不明白如何使用过滤器。在这种特殊情况下，谁能解释一下这些过滤器。

import boto3
client = boto3.client('ec2')
# Completed "aws configure" Access ID, Secret Key, Region in terminal

# I am Trying to get all the publicly available Windows AMI's
response = client.describe_images(
   ExecutableUsers=[
       'all',
   ],
   Filters=[
       {
           'Name': 'platform',
           'Values': [
               'windows',
           ]
       },
   ],
   Owners=[
       '679593333241', # all public ami's from amazon as owner
   ]
)
print(response)
# OUTPUT: I get a collection of available windows AMI
# A collection with all windows as its platfrom


# ----------------------Code 2-------------------------------------------

robot = boto3.client('ec2')
# Completed "aws configure" Access ID, Secret Key, Region in terminal

# I am Trying to get all the publicly available OpenSUSE AMI's
response2 = robot.describe_images(
   ExecutableUsers=[
       'all',
   ],
   Filters=[
       {
           'Name': 'platform',
           'Values': [
               'OpenSUSE', # No response other than Windows
           ]
       },
   ],
   Owners=[
       '679593333241',
   ],
)
print(response2)
# OUTPUT: I get empty collection
# A collection with all OpenSUSE as its platform is expected.
