flake8 Github Action

This is a Github Action to run flake8 against your repository. It uses the new Github Actions API and JavaScript toolkit. It does fancy things like add annotations to your PRs inline.

Use it in your project like:

(in .github/workflows/lint.yml)

name: Lint

on:
  push:
    paths:
      - '*.py'

jobs:
  flake8_py3:
    runs-on: ubuntu-latest
    steps:
      - name: Setup Python
        uses: actions/setup-python@v1
        with:
          python-version: 3.7.4
          architecture: x64
      - name: Checkout PyTorch
        uses: actions/checkout@master
      - name: Install flake8
        run: pip install flake8
      - name: Run flake8
        uses: suo/flake8-github-action@releases/v1
        with:
          checkName: 'flake8_py3'   # NOTE: this needs to be the same as the job name
        env:
