我不知道MacOS上这些第三方Python软件包的安装位置？

Question

I'm currently doing Natural Language Processing with Python. I installed NLTK package by using pip install nltk . I have several Pythons on my Mac, but I use 3.4 mostly.

Now, I've downloaded a segmenter from Stanford that could do Chinese language segmentation( Stanford Word Segmenter ), but it might need me to do some changes on the original NLTK package, namely, I have to write an API file called stanford_segmenter.py and then put it into the nltk/tokenize/ directory.

The problem is I don't really know where the NLTK package having been installed, I actually don't know where the lib directory of Python 3.4 is on MacOS. Anyone could help me?

A generic approach to locating a package in the file system is importing it and looking at the __file__ attribute.

On the commandline, you can eg run

python -c "import nltk; print(nltk.__file__)"

It will show you where the top level nltk (probably __init__.py ) file is located.
