h5py の cygwin 対応が不完全らしく、インストールに失敗する。
更には、rebase 案件らしき DLL の読み込み障害も。

• libhdf5-devel
• libnetcdf-devel

以下のコマンド

pip3 install pymc3

でインストールすると h5py のところで止まる。
とりあえず、アドホックな解決方法は以下のページにまとめた。

• 20200205: Cygwin - Python3 - h5py

とりあえず、h5py だけクリアできれば、インストールは出来るのだが、import すると DLL で address error らしきものが出る。

>>> import pymc3
      0 [main] python3.6m 29803 child_info_fork::abort: address space needed by 'period.cpython-36m-x86_64-cygwin.dll' (0x400000) is already occupied

model を作ってみると以下のようにエラーになり動作しなかった

>>> with pymc3.Model() as model:
...   x = pymc3.Normal('x')
...   trace = pymc3.sample(1000)
...

これは rebase 案件かな？
pip3 絡んだ rebase はどうすりゃ良いんだっけ？
多分 ruby gem でも同様の事起こりそうな気がするし、apt-cyg の機能拡張すべきだろうか？
