If you are installing apache-airflow-providers-snowflake with requirements.txt and getting a webserver that won’t come up properly, your issue is very likely an incompatiblity in packages. If you add snowflake-sqlalchemy>=1.1.0,<1.3 to your requirements.yml, it should work. This is an issue with the way the version of pip being used (currently pip 19) resolves dependencies.
