The proto-oom from harupy

proto-oom's Introduction

TL;DR

This repo is a minimum replication of an issue we encountered in https://github.com/mlflow/mlflow. Related to mlflow/mlflow#9360. We thought separating package and folder would fix the issue, but it didn't. Well, it did solve the error reported in #9360, but a new error showed up.

Command to reproduce the error

git clone https://github.com/harupy/proto-oom
cd proto-oom
docker build .
