我已经在亚马逊ec2微实例(Ubuntu 13.04)的默认python编译器中成功安装了scipy
。但是我无法在virtualenv中安装scipy
。
pip install scipy
以此错误结束
scipy/sparse/sparsetools/csr_wrap.cxx: In function ‘void init_csr()’:
scipy/sparse/sparsetools/csr_wrap.cxx:73303:21: warning: variable ‘md’ set but not used [-Wunused-but-set-variable]
c++: internal compiler error: Killed (program cc1plus)

一种解决方案是临时启用微实例的交换。如此SO post所述,通过以下方式启用1gb交换:
sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
sudo /sbin/mkswap /var/swap.1
sudo /sbin/swapon /var/swap.1
打开交换后,通过pip安装scip:
sudo apt-get install -y libatlas-base-dev gfortran python-dev build-essential g++
sudo pip install numpy
sudo pip install scipy
scipy成功安装后,您可以通过以下方式禁用它:
sudo swapoff /var/swap.1
sudo rm /var/swap.1

这对我有用:
pip --no-cache-dir install scipy
见:
Memory error while using pip install Matplotlib

注意:

是的,512MB不足以编译该C ++文件。
您最好的选择是将Scipy构建为二进制包(bdist,或eggs,或更现代的wheels),例如在具有兼容环境的其他计算机上通过python setupegg.py bdist_egg
。例如,在虚拟机中使用与EC2实例类似的Linux版本。
一般来说,记住当pip
安装包时,它会编译源文件。如果包不是很小,这是低效的,并且最好使用二进制包。 wheel
包格式应与pip一起使用。

对我而言,错误略有不同。
Blas (http://www.netlib.org/blas/) libraries not found.
Directories to search for the libraries can be specified in the
numpy/distutils/site.cfg file (section [blas]) or by setting
the BLAS environment variable.

Command /home/kdixit/pyvirt/bin/python -c "import setuptools;__file__='/home/kdixit/pyvirt/build/scipy/setup.py';exec(compile(open(__file__).read().replace('\r\n
因此我必须安装
sudo apt-get install libblas-dev
然后它奏效了。
答案 4 :(得分:1)
我在scipy
的{{1}}编译过程中遇到虚拟内存错误,我认为t2.micro
编译得很好。无论如何,我想 Dolan Antenucci 的答案可以解决我的问题,但我转而采用了另一种方式,一种妥协方式,确实有效。
我正在运行numpy
个实例,请记住这一点。
Ubuntu
妥协的是,您将无法在不同的虚拟环境中使用不同的版本,并且您将与回购中的版本绑定。
