The graph module uses Protocols, which is natively supported since Python 3.8 (the required minimum version for DoWhy). To support Protocols in earlier Python versions, an extension provided Protocol support. However, this extension can causes compatibility issues with newer versions of other packages. DoWhy now uses the Protocol implementation that is available since Python 3.8. Signed-off-by: Patrick Bloebaum <bloebp@amazon.com>
