Question

我正在使用Google Cloud DataLab，这是在Google的云计算引擎上运行的ipython笔记本，我试图安装python模块keras，但笔记本声称它无法找到它。我正在运行Python3（并在安装后重新启动内核）。一切似乎都安装在Python2.7文件夹中 - python3内核无法找到它吗？以下是一些有用的日志和错误消息：

print(platform.python_version())
!pip install keras==2.1.1
!pip show keras
import keras

ImportError: No module named 'keras'

Answer 1

尝试pip3 install keras==2.1.1

pip将使用默认版本的pip安装它，该版本适用于Python 2.7（您可以查看pip -V）

pip3将始终是pip的Python 3版本。

Answer 2

我遇到了类似的问题，在我的情况下，解决方案与Chris Meyers的建议相反：我需要使用pip而不是pip3。

仔细检查发现，pip3正在将我需要的模块安装到python3.5文件夹中，而我的内核正在查看python3.7。

Google Cloud DataLab中找不到该模块
