Try to install it as a python package using pip. You said you already tried:
尝试使用 pip 将其安装为 python 包。你说你已经试过了：
sudo apt-get install python-scipy
Now run:
现在运行：
pip install scipy
I ran both and it worked on my Debian-based box.
我运行了两者，它在我的基于 Debian 的机器上运行。

Your python don't know where you installed scipy. add the scipy path to PYTHONPATHand I hope it will solve your problem.
你的 python 不知道你在哪里安装了 scipy。将 scipy 路径添加到PYTHONPATH，我希望它能解决您的问题。

I recommend you to remove scipy via
我建议您通过以下方式删除 scipy
apt-get purge scipy
and then to install it by
然后安装它
pip install scipy
If you do both then you might confuse you deb package manager due to possibly differing versions.
如果两者都做，那么由于版本可能不同，您可能会混淆 deb 包管理器。

To ensure easy and correct installation for python use pip from the get go
为确保 Python 的简单和正确安装，请从一开始就使用 pip
To install pip:
要安装 pip：
$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python2 get-pip.py # for python 2.7
$ sudo python3 get-pip.py # for python 3.x
To install scipy using pip:
使用 pip 安装 scipy：
$ pip2 install scipy # for python 2.7
$ pip3 install scipy # for python 3.x

If you need to get scipyin your Pyhton environment on Windows you can get the *.whl files here:
如果您需要进入scipyWindows 上的 Pyhton 环境，您可以在此处获取 *.whl 文件：
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
Remember that you need to install numpy+mklbefore you can install scipy.
请记住，您需要先安装，numpy+mkl然后才能安装scipy。
http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
When you have downloaded the correct *.whl files just open a cmd prompt in the download directory and run pip install *.whl.
下载正确的 *.whl 文件后，只需在下载目录中打开 cmd 提示符并运行pip install *.whl.

My problem was that I spelt one of the libraries wrongly when installing with pip3, which ended up all the other downloaded libaries in the same command not being installed. Just run pip3 install on them again and they should be installed from their cache.
我的问题是，在使用 pip3 安装时，我拼错了其中一个库，最终导致未安装同一命令中的所有其他下载的库。只需再次对它们运行 pip3 install ，它们就应该从它们的缓存中安装。
