# This script is for building AARCH64 wheels using AWS EC2 instances.
# To generate binaries for the release follow these steps:
# 1. Update mappings for each of the Domain Libraries by adding new row to a table like this: "v1.11.0": ("0.11.0", "rc1"),
# 2. Run script with following arguments for each of the supported python versions and specify required RC tag for example: v1.11.0-rc3:
# build_aarch64_wheel.py --key-name <YourPemKey> --use-docker --python 3.7 --branch <RCtag>
