Welcome¶ Theano is a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. Theano features: tight integration with NumPy – Use numpy.ndarray in Theano-compiled functions. transparent use of a GPU – Perform data-intensive computations much faster than on a CPU. efficient symbolic differentiation – Theano does your d

I was inspired by "Prime Number Pattern P Mod 40" by Jason Padgett. Padgett was mugged in 2002, sustaining a head injury that caused "a form of synesthesia and savant syndrome". Jason sees visions of geometrical and mathematical forms and illustrates them. Here's a video about him. As a fan of prime numbers myself and having been teaching them to my son, I decided to replicate his prime number dra

If all subsystems can communicate with all other subsystems, you lose the benefit of separating them at all. Make each subsystem meaningful by restricting communications. Steve McConnell Below is a tool for examining how modules in a Python package communicate with each other. Module Graph Each node in this graph is a module in the selected package. Edges indicate imports. Placing the mouse over a

How To Package Your Python Code¶ This tutorial aims to put forth an opinionated and specific pattern to make trouble-free packages for community use. It doesn’t describe the only way of doing things, merely one specific approach that works well. In particular, packages should make it easy: To install with pip or easy_install. To specify as a dependency for another package. For other users to downl

pythonbrew が今後開発を停止するということで pyenv に移行してみたら、想像以上に Life Changing だったので久々にブログに書きます。 以下のような方に pyenv の導入はおすすめです。 rbenv のコマンド体系に慣れている 日常的に複数の python プロジェクトを横断する screen, tmux のような Terminal Multiplexer を使っていて息を吸うように新しい shell を起動する なぜおすすめかというと日常的に使っていた virtualenv の環境切り替えに使う workon コマンドが不要になったからなんですね。 これは pyenv の plugin である python-virtualenv のおかげです。 python-virtualenv ではこれまで virtualenv が担っていた役割を pyenv に移譲するこ

Wed 31 October 2012 By Dominik Dabrowski In Blog. In my years of programming in Python and roaming around GitHub's Explore section, I've come across a few libraries that stood out to me as being particularly enjoyable to use. This blog post is an effort to further disseminate that knowledge. Please note that I've specifically excluded libraries like sqlalchemy and Flask that are too obviously awe

このように，シェルへの出力を色付けする．例えば，エラーなどの処理は目立つように赤色にできると良い． ここでは，echoを使った場合，Python、Ruby，そしてPerlの出力の色を変えてみる． 色づけはエスケープシーケンスを記述すれば書ける． 基本構文
