Manage custom image libraries - Content Moderation - Alibaba Cloud Documentation Center

This topic describes how to use Content Moderation SDK for Python to manage custom image libraries.

Description

You can customize image samples based on your management requirements for personalized content. Then, you can use custom image libraries to intelligently detect pornographic content, terrorist content, and ad violations in images and videos. For more information about the related parameters, see CreateImageLib.

Prerequisites

Python dependencies are installed. For more information, see Installation.
Note
You must use the required Python version described in the Installation topic to install the dependencies. Otherwise, subsequent operation calls fail.
The Extension.Uploader utility class is downloaded and imported into your project.

Query custom image libraries

You can use the following code to query image libraries, including custom image libraries and feedback-based image libraries:

# coding=utf-8

from aliyunsdkcore import client
from aliyunsdkcore.profile import region_provider
from aliyunsdkgreen.request.v20170823 import DescribeImageLibRequest

# Note: We recommend that you reuse the instantiated client as much as possible. This improves moderation performance and avoids repeated client connections. 
# Common ways to obtain environment variables:
# Obtain the AccessKey ID of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID']
# Obtain the AccessKey secret of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET']
clt = client.AcsClient("We recommend that you obtain the AccessKey ID of your RAM user from environment variables", "We recommend that you obtain the AccessKey secret of your RAM user from environment variables", "cn-shanghai")
region_provider.modify_point('Green', 'cn-shanghai', 'green.cn-shanghai.aliyuncs.com')
# The request object cannot be reused. You must create a request object for each request. 
request = DescribeImageLibRequest.DescribeImageLibRequest()
request.set_ServiceModule("open_api")
response = clt.do_action_with_exception(request)
print(response)

Create a custom image library

You can use the following code to create a custom image library:

Note

Set the parameters based on your business scenario.

# coding=utf-8
from aliyunsdkcore import client
from aliyunsdkcore.profile import region_provider
from aliyunsdkgreen.request.v20170823 import CreateImageLibRequest

# Note: We recommend that you reuse the instantiated client as much as possible. This improves moderation performance and avoids repeated client connections. 
# Common ways to obtain environment variables:
# Obtain the AccessKey ID of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID']
# Obtain the AccessKey secret of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET']
clt = client.AcsClient("We recommend that you obtain the AccessKey ID of your RAM user from environment variables", "We recommend that you obtain the AccessKey secret of your RAM user from environment variables", "cn-shanghai")
region_provider.modify_point('Green', 'cn-shanghai', 'green.cn-shanghai.aliyuncs.com')
# The request object cannot be reused. You must create a request object for each request. 
request = CreateImageLibRequest.CreateImageLibRequest()
request.set_ServiceModule("open_api")
request.set_Name("Pornography detection blacklist")
request.set_Scene("PORN")
request.set_Category("BLACK")
response = clt.do_action_with_exception(request)
print(response)

Modify a custom image library

You can use the following code to change the name of a custom image library and the business scenario to which the custom image library applies:

# coding=utf-8

from aliyunsdkcore import client
from aliyunsdkcore.profile import region_provider
from aliyunsdkgreen.request.v20170823 import UpdateImageLibRequest

# Note: We recommend that you reuse the instantiated client as much as possible. This improves moderation performance and avoids repeated client connections. 
# Common ways to obtain environment variables:
# Obtain the AccessKey ID of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID']
# Obtain the AccessKey secret of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET']
clt = client.AcsClient("We recommend that you obtain the AccessKey ID of your RAM user from environment variables", "We recommend that you obtain the AccessKey secret of your RAM user from environment variables", "cn-shanghai")
region_provider.modify_point('Green', 'cn-shanghai', 'green.cn-shanghai.aliyuncs.com')
# The request object cannot be reused. You must create a request object for each request. 
request = UpdateImageLibRequest.UpdateImageLibRequest()
request.set_Id(12345)
request.set_Name("New name of the image library")
request.set_Scene("PORN")
request.set_Category("WHITE")
response = clt.do_action_with_exception(request)
print(response)

Delete a custom image library

You can use the following code to delete a custom image library:

Note

If you delete a custom image library, all images in the library are also deleted.

# coding=utf-8
from aliyunsdkcore import client
from aliyunsdkcore.profile import region_provider
from aliyunsdkgreen.request.v20170823 import DeleteImageLibRequest

# Note: We recommend that you reuse the instantiated client as much as possible. This improves moderation performance and avoids repeated client connections. 
# Common ways to obtain environment variables:
# Obtain the AccessKey ID of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID']
# Obtain the AccessKey secret of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET']
clt = client.AcsClient("We recommend that you obtain the AccessKey ID of your RAM user from environment variables", "We recommend that you obtain the AccessKey secret of your RAM user from environment variables", "cn-shanghai")
region_provider.modify_point('Green', 'cn-shanghai', 'green.cn-shanghai.aliyuncs.com')
# The request object cannot be reused. You must create a request object for each request. 
request = DeleteImageLibRequest.DeleteImageLibRequest()
request.set_Id(12345)
response = clt.do_action_with_exception(request)
print(response)

Query images in a custom image library

You can use the following code to query all images that have been added to a custom image library:

# coding=utf-8

from aliyunsdkcore import client
from aliyunsdkcore.profile import region_provider
from aliyunsdkgreen.request.v20170823 import DescribeImageFromLibRequest

# Note: We recommend that you reuse the instantiated client as much as possible. This improves moderation performance and avoids repeated client connections. 
# Common ways to obtain environment variables:
# Obtain the AccessKey ID of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID']
# Obtain the AccessKey secret of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET']
clt = client.AcsClient("We recommend that you obtain the AccessKey ID of your RAM user from environment variables", "We recommend that you obtain the AccessKey secret of your RAM user from environment variables", "cn-shanghai")
region_provider.modify_point('Green', 'cn-shanghai', 'green.cn-shanghai.aliyuncs.com')
# The request object cannot be reused. You must create a request object for each request. 
request = DescribeImageFromLibRequest.DescribeImageFromLibRequest()
request.set_ImageLibId(12345)
request.set_PageSize(10)
request.set_CurrentPage(1)
response = clt.do_action_with_exception(request)
print(response)

Remove images from a custom image library

You can use the following code to remove multiple images from a custom image library:

# coding=utf-8

from aliyunsdkcore import client
from aliyunsdkcore.profile import region_provider
from aliyunsdkgreen.request.v20170823 import DeleteImageFromLibRequest

# Note: We recommend that you reuse the instantiated client as much as possible. This improves moderation performance and avoids repeated client connections. 
# Common ways to obtain environment variables:
# Obtain the AccessKey ID of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID']
# Obtain the AccessKey secret of your RAM user: os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET']
clt = client.AcsClient("We recommend that you obtain the AccessKey ID of your RAM user from environment variables", "We recommend that you obtain the AccessKey secret of your RAM user from environment variables", "cn-shanghai")
region_provider.modify_point('Green', 'cn-shanghai', 'green.cn-shanghai.aliyuncs.com')
# The request object cannot be reused. You must create a request object for each request. 
request = DeleteImageFromLibRequest.DeleteImageFromLibRequest()
request.set_Ids("['669310']")
response = clt.do_action_with_exception(request)
print(response)
