It is possible to use a docker image as the project interpreter in PyCharm. This can be helpful for when extractors require dependencies that can be difficult to install (like GDAL). Since a docker image will eventually be created for any extractor, it makes sense to build this into the development process as early as possible. This also ensures that the local environment will be the same as the docker image. The problem of something working locally (but not in docker) or an extractor that runs (but not locally) can be avoid using this method.
