I believe this is a known issue in plotnine https://github.com/has2k1/plotnine/issues/619 and fix in the latest plotnine version https://github.com/has2k1/plotnine/commit/c48d5a26ab0d0a54ed47bbefc6a83b5fcb2af616, so we would need to install at least plotnine ~= v0.10.0, but this version has conflict with idmtools requirement, the latest version which meets the idmtools requirement is v0.8.0. If we upgrade our requirement for plotnine to 0.10.0, installation will fail, please see #49 for details
