python - Trouble installing scipy in virtualenv on a amazon ec2 linux micro instance -


i have installed scipy in default python compiler on amazon ec2 micro instance (ubuntu 13.04). not able install scipy in virtualenv.

pip install scipy ends error

scipy/sparse/sparsetools/csr_wrap.cxx: in function ‘void init_csr()’:  scipy/sparse/sparsetools/csr_wrap.cxx:73303:21: warning: variable ‘md’ set not used [-wunused-but-set-variable]  c++: internal compiler error: killed (program cc1plus)  please submit full bug report,  preprocessed source if appropriate.  see <file:///usr/share/doc/gcc-4.7/readme.bugs> instructions.  ---------------------------------------- cleaning up... command /home/ubuntu/pnr/bin/python -c "import setuptools;__file__='/home/ubuntu/pnr/build/scipy/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-t8drvd-record/install-record.txt --single-version-externally-managed --install-headers /home/ubuntu/pnr/include/site/python2.7 failed error code -9 in /home/ubuntu/pnr/build/scipy

before asks. pip freeze default compiler returns

one solution temporarily enable swap on micro instance. described @ so post, enable 1gb swap via:

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

once swap on, install scipy via pip:

sudo apt-get install -y libatlas-base-dev gfortran python-dev build-essential g++ sudo pip install numpy sudo pip install scipy

once scipy installs, can disable via:

sudo swapoff /var/swap.1 sudo rm /var/swap.1
