エラー出たときの環境

$ docker-compose -v
docker-compose version 1.25.0, build unknown
$ docker -v
Docker version 20.10.12, build 20.10.12-0ubuntu2~20.04.1

結局、docker engineを最新に更新して、docker compose(docker-composeではなく)を使ったらビルド成功した

$ docker --version
Docker version 24.0.4, build 3713ee1
$ docker compose version
Docker Compose version v2.19.1
$ docker compose -f docker-compose.pytorch.yaml build
[+] Building 0.2s (11/11) FINISHED 

以下メモ

どうやら、Docker Engine version 23.0.0からdocker-buildx-pluginが分離されているようだった

https://docs.docker.com/engine/release-notes/23.0/
From Docker Engine version 23.0.0, Buildx is distributed in a separate package: docker-buildx-plugin. In earlier versions, Buildx was included in the docker-ce-cli package. When you upgrade to this version of Docker Engine, make sure you update all packages. For example, on Ubuntu:

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

sudo apt update -y
sudo apt upgrade -y

Docker再インストール

以下の通り最新にすることができました

$ docker --version
Docker version 24.0.4, build 3713ee1
$ docker compose version
Docker Compose version v2.19.1
