我已成功安装scipy在亚马逊ec2微实例(Ubuntu 13.04)上的默认python编译器中.但是我无法安装scipyvirtualenv.

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)

我正在关注http://www.enigmeta.com/2012/08/16/starting-flask/上的教程,使用mod_wsgi开发和部署一个简单的烧瓶应用程序到Apache.我想我已经把它缩小到我的Apache配置中的一个缺陷.如果我从命令行运行helloflask.py,它工作正常.我可以通过wget从localhost:5000的另一个shell访问它,我得到了正确的响应.我还有其他虚拟主机(非wsgi)启动并运行,所以我知道Apache正在运行并响应端口80上的其他请求.

我有以下结构:

/sites/helloflask.mydomain.com
   /helloflask
      application.wsgi
      helloflask.py
      (rest of env from virtualenv)
   /log
      access.log
      error.log

helloflask.py:

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":
    app.run()

application.wsgi:

import os, sys, logging
logging.basicConfig(stream=sys.stderr)

PROJECT_DIR = '/sites/helloflask.mydomain.com/helloflask'

activate_this = os.path.join(PROJECT_DIR, 'bin', 'activate_this.py')
execfile(activate_this, dict(__file__=activate_this))
sys.path.append(PROJECT_DIR)

from helloflask import app as application

Apache配置:/etc/apache2/sites-available/helloflask.mydomain.com

pymongo是否提供API来启用集合和行的备份或导出？

在youtube界面中,如果我们搜索具有拼写错误的术语,Interface会提供一个选项来"搜索"以查找类似的术语.例如, poovin maarile搜索为您提供结果poovin marile

但是使用youtube api版本3时,poovin maarile结果为零,并poovin marile提供230+结果.但是在api中没有办法得到这个非常密切相关的术语.

我知道版本2中的拼写建议功能,但由于版本2已弃用,我对使用它不感兴趣.youtube data api版本3有类似的东西吗？
