Docker delete error response from daemon: Conflict: unable to delete xxxxx solution

An error is reported when the docker image is deleted. After docker images , the output is as follows:

REPOSITORY                             TAG                        IMAGE ID            CREATED             SIZE

The first image is successfully deleted by docker RMI 74f5aea45cf6 directly. However, the latter two images appear in pairs, and the direct docker RMI deletion fails. The error message is as follows:

Error response from daemon:
conflict: unable to delete b3cd25f64a2a (must be forced) - image 
is referenced in multiple repositories

Solution:

First, specify a name when docker RMI , instead of image ID , and then execute docker RMI - f image ID J

docker rmi paddlepaddle/paddle:1.1.0-gpu-cuda8.0-cudnn7
docker rmi -f b3cd25f64a2a
