# How to test the Linux jobs:
#   - Install CircleCI local CLI: https://circleci.com/docs/2.0/local-cli/
#   - circleci config process .circleci/config.yml > gen.yml && circleci local execute -c gen.yml --job binary_linux_wheel_py3.7
#     - Replace binary_linux_wheel_py3.7 with the name of the job you want to test.
#       Job names are 'name:' key.
