最近、会社でAIを業務に活用できないかという観点で、AIのAPIやAIライブラリのTensorFlowを確認している。
会社のMacにはもちろん、TensorFlowをインストールしている。
そんで、自宅MacにもTensorFlowの環境を構築することにした。
参考にしたサイトは次の通り。
Python3 TensorFlow for Mac 環境構築
ちなみにボクのmacOSは、10.13.4(macOS High Sierra)。
実施した手順は次から。
全てターミナルでコマンド入力。
1. Xcode Command Line tools
xcode-select --install
xcode-select: note: install requested for command line developer tools
2. Homebrewは以前にインストールしているので、homebrewからpyenvをインストール。
brew install pyenv

A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
/usr/local/etc/openssl/certs
and run
/usr/local/opt/openssl/bin/c_rehash
This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.
If you need to have this software first in your PATH run:
