Getting unknown flag: --platform

[cs-mshah]

I am running cog on mac, using colima and also have installed buildx with brew install docker-buildx. But upon running cog run python, I get the following error: unknown flag: --platform. Can you help fix this?

@cs-mshah I can't reproduce this locally, but it sounds like you might be using an old version of BuildKit. Can you share the outputs of the following commands?

docker version
docker buildx version

Output of docker version:

docker buildx version docker: 'buildx' is not a docker command.

But I did install docker buildx using brew install docker-buildx

@cs-mshah It could be that your PATH is configured to use something other than what Homebrew installed.

Could you try the following?

$ which docker

If that includes /opt/homebrew or /usr/local/bin, then you are running the Homebrew command.

In which, case you might try uninstalling docker-buildx and installing docker:

$ brew uninstall docker-buildx
$ brew install docker

The issue still persists.

I am getting this same issue.

@michaelevensen you should have docker buildx plugin

@cs-mshah Encountered the same issue (M1 MacBook Air), but resolved now.

Fix is to install Docker Desktop instead of installing docker and docker-buildx separately through brew.

So brew uninstall docker, brew uninstall docker-buildx. Install Docker Desktop. Open after installation, run through setup. cog run python from docs/getting-started.md should now work.
