jupyter-notebook - 虚拟环境中的 Jupyter Notebook 看不到虚拟环境包

Question

我正在尝试在虚拟环境中使用 Jupyter Notebook。
我创建了一个新的 virtualenv virtualenv ker12+ 激活 + 安装特定版本的 keras 或任何其他库。

也如 Using a virtualenv in an IPython notebook 中所述我做了:
pip install ipykernel
和
python -m ipykernel install --user --name=my-virtualenv-name
当我运行笔记本并写! which jupyter输出是正确的

/Users/myname/virtualenv/ker12/bin/python

但是当我尝试导入库时，例如 import keras有错误。

ImportError: No module named keras

但另一方面，当我写 pip freeze | grep Keras输出是:

Keras==1.2.0

更新 1:

此问题与 无关凯拉斯 它与任何其他库一起出现(例如 pandas )

如果我打印 os.path输出如下:

<'module 'posixpath' from /usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/posixpath.pyc>

从“命令行 python” os.path 看起来是正确的

<'module 'posixpath' from '/Users/my_name/virtualenv/ker12/lib/python2.7/posixpath.pyc'>

更新 2:

如果我打印 sys.path来自终端和 jupyter输出也不同:

从终端
