Docker TensorFlow

docker Python

『pythonによるスクレイピング&機械学習 開発テクニック』
の５章 (5-2)だけ試してみた。

docker run -it b.gcr.io/tensorflow/tensorflow:latest-devel

本の通りにpython3で試したらエラー。

python 2系だといけた。

rmする時、ワイルドカードでマッチするファイルの内、一つだけ除外したい場合

メモ MacOS

~/Documents/ に
FileZilla_ で始まる消したいファイルがあったけど、
最新の１個だけ残しておきたかった時のメモ。

rm FileZilla_*
で全部消せたけど、マッチするファイルの内１個だけ残したい。
同じディレクトリに消したくないファイルが他にある。

find . -type f -name 'FileZilla*' -not -name 'FileZilla_3.23.0.2_macosx-x86.app.tar.bz2' -print0 | xargs -0 rm

bash - rm all files except some - Stack Overflow

コマンドが長すぎてめんどくさい。

macOSにpipが入っていない

Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can install
pip via the instructions at:
