The error [internal] load metadata for docker.io/library/python:3 error typically occurs when you are trying to pull or run a Docker image from the Docker Hub registry and there is a problem with the metadata for the image.
The metadata for a Docker image includes information about the image layers, their sizes, and the dependencies between them.
When you pull an image from the registry, Docker downloads the metadata for the image and uses it to build the image on your local system. If there is a problem with the metadata, Docker may be unable to build the image correctly.
To troubleshoot this issue, you can try the following steps:
1.Check your internet connection to ensure that it is stable and working correctly.
2.Try pulling the image again using the docker pull command. If the issue persists, try pulling the image from a different registry (e.g. quay.io) or using a different version of the image (e.g. python:3.10).
3.If you are still unable to pull the image, you can try deleting the image from your local system and pulling it again. To delete the image, use the docker rmi command followed by the image name and tag (e.g. docker rmi python:3).
If you are still having trouble after trying these steps, it may be helpful to review the Docker documentation or consult with the Docker community for further assistance.
