无法在Jupyter中导入Keras [英] Unable to import Keras in Jupyter

问题描述

因此，我使用python 3和jupyter(使用pip)设置了虚拟局域网.一切正常，但如果我尝试导入keras，它将无法在jupyter中工作，并告知未找到模块.但是，如果我在终端中执行相同的文件(python3 test.py)，就可以正常工作.

So I set up my virtual lan with python 3 and jupyter (with pip). All works fine but if I try to import keras it will not work in jupyter and tells module not found. But if I execute the same file (python3 test.py) in the terminal it works fine.

which jupyter
/usr/local/bin/jupyter

which python3
/Users/niro273/Desktop/xcorp/bin/python3

如果我执行pip3 list，这些就是结果.

If I do a pip3 list these are the results.

jupyter (1.0.0)
jupyter-client (5.1.0)
jupyter-console (5.2.0)
jupyter-core (4.3.0)
Keras (2.0.8)

注意-我也在虚拟环境中安装了jupyter(pip3 install jupyter).因此，我是否必须切换木贼执行路径?不胜感激.

Note- I have installed jupyter (pip3 install jupyter) inside the virtual env too. So should I have to switch the juypter execution path ? Would appreciate any guidance.

推荐答案

都是Keras& Jupyter必须安装在您的虚拟环境中；然后，您应该在激活虚拟环境后启动Jupyter(在这种情况下，which jupyter应该指向虚拟环境中的其他位置):

Both Keras & Jupyter must be installed inside your virtual environment; then, you should start Jupyter after activating your virtual env (in which case which jupyter should point to a different location inside your virtual env):

$ which jupyter
/usr/local/bin/jupyter
$ virtualenv /venv/foo
$ source /venv/foo/bin/activate
$ (foo) pip3 install jupyter
$ (foo) which jupyter
/venv/foo/bin/jupyter
$ (foo) pip3 install keras
$ (foo) jupyter notebook

当然还有其他方法(例如安装另一个内核，指向foo虚拟环境中的Python可执行文件)，但是我发现上述方法更快，更轻松，至少对于Keras而言.

There are certainly other ways (e.g. to install a different kernel in your main Jupyter installation pointing to the Python executable in your foo virtual environment), but I have found the above way to be quicker and more hassle-free, at least for Keras...
