Question

当我想在Jupyter笔记本中执行我的代码时，我收到此错误：

基本上，想知道为什么Jupyter正在寻找Library/Frameworks/Python.framework/Versions/3.4/bin/python3（它不存在）而不是Anaconda版本？还有，如何设置它以使用Anaconda Python？

使用Anaconda重新安装Python3，现在内核工作正常：

Monas-MacBook-Pro:~ mona$ pip -V
pip 9.0.1 from /Users/mona/anaconda/lib/python3.6/site-packages (python 3.6)
Monas-MacBook-Pro:~ mona$ python -c 'import pkg_resources'
Monas-MacBook-Pro:~ mona$ python -c 'import setuptools'
Monas-MacBook-Pro:~ mona$ jupyter notebook
