GMT/Pythonの開発がこちらで進められ,一通りの機能が実装されたようですので,試用してみます.現在のところ,Windows版はサポートされていませんので,WSL上のLinux (Ubuntu 16.04)で行います.

GMT-6のインストール

こちらのページを参考にインストールを行います.Anaconda3がインストールされていることを前提にします.conda environmentで専用の環境を構築することが勧められていますので,これに従います.こうすることで,これまでに構築してきた環境を汚染することなく,試用ができます.
最初にPython3.6とpipだけがインストールされたconda environment(gmt-python)を構築します.

$ conda create --name gmt-python python=3.6 pip

この環境をactivateします.

$ source activate gmt-python

ちなみに,現在の環境は

$ conda info -e

で確認できます.また,元の環境に戻すには

$ source deactivate

です.
GMT-6をインストールします.これは非常に時間がかかります.私の環境では既にGMT-6のビルドを行いましたので二重にインストールすることになりますが,干渉はしません.

$ conda install gmt -c conda-forge/label/dev -c conda-forge

最後に他の依存関係にあるパッケージをインストールします.

$ conda install numpy -c conda-forge

以上でGMT-6のインストールはおわりです.

GMT/Pythonのインストール

pipでGMT/Pythonをインストールします.

$ pip install https://github.com/GenericMappingTools/gmt-python/archive/master.zip

さらに,後で必要となる依存パッケージをいくつかインストールしておきます.

$ conda install pytest pytest-mpl -c conda-forge

テスト

最後にテストしましょう.Pythonの環境(例えば,Jupyter notebook)で以下のようにタイプします.

import gmt
gmt.test()

その結果,以下のようになり大丈夫のようです.1回目は一つWarningが出ましたが,以下のように2回目に実行したらWarningが出なくなっていました.
