時代は人工知能。機械学習。深層学習。
TensorFlowに続き、ゼロから作るDeep LearningなどiPhone上で動作するPython環境であるPythonistaで機械学習の動作ができないものか検証してきました。
その失敗の連続の第3弾。
最近この記事にコメントをいただきました。ChainerはPythonistaで動くのか？というお話です。
Chainerとは？
実はあまり知らなかったので、調べてみました。
うむ。要はGoogleが開発したTensorFlowのような機械学習のためのライブラリですね。これも使えれば将来的に会社に行かなくてもお金が稼げるようになるかもしれません。
早速インストール
やってみました。ただ、以下の記事を参考にしたのですが、そもそもMacでも動かなかった様子。
そもそもGPUを使用するみたいで、やる前からなんとなく結果が見えてそうな気がしましたが、とりあえずやるだけやってみました。
StaSh v0.6.17

んー。やはりエラーだのワーニングだの出てますね。単純にpipからのインストールは無理そうです。念のためコンソールから叩いてみましたが、

importでエラーがでますね。正しくインストールはできていない模様。あまり時間もなかったので一旦ここまでにして、入れかけたChainerは削除しておきます。
[~/Documents]$ pip remove chainer Package removed. Removing dependency: filelock Package removed. Removing dependency: nose Package removed. Removing dependency: protobuf Package removed. [~/Documents]$
Pythonista3に新たにライブラリを入れるのがなかなかうまく行かないですね。もう少し研究が必要そうです。とりあえず今回はここまで。
