Check Python library version

Python library authors put the version number in <module>.__version__

python -c 'import keras; print(keras.__version__)'

install Python package from "requirements.txt"

pip install -r requirements.txt

存與依據環境檔創建環境

想像在一台電腦以conda建立了一個環境開發某專案，如何讓程式在其他人的電腦上有一樣的環境能重現並開發該專案呢？這時只要使用conda env export > environment.yaml記錄下環境的相關資訊檔environment.yaml，將它放到另一台電腦上然後以conda env create -f environment.yaml載入並建立該環境，如此一來就能在另一台電腦重現了環境並開發該專案了。

儲存環境 conda env export > environment.yaml
依據環境檔創建環境 conda env create -f environment.yaml

conda env export > environment.yaml     # in PC A
conda env create -f environment.yaml    # in PC B
