在apache服务器上导入 pandas 导致超时错误 [英] Import Pandas on apache server causes timeout error

问题描述

我有一个Django项目在Apache服务器上工作。

我安装了大熊猫，并希望使用它开始操纵数据 - 但是奇怪的是发生了。

随着我在生产环境中使用 import pandas ，服务器将挂断（一段时间后）抛出408超时错误。

我可以注释掉 pandas 部分，服务器正常响应而无问题。我不能在django的开发环境或命令行界面中重新创建它。

这里是 httpd-app.conf file：

  Alias / tooltrack / staticC：/ Users / myfolder / Bitnami Django Stack Projects / tooltrack / static /
< DirectoryC：/ Users / myfolder / Bitnami Django Stack Projects / tooltrack / static /> 
选项+ MultiViews 
 AllowOverride全部
< IfVersion< 2.3> 
订单允许，拒绝
允许从所有
< / IfVersion> 
< IfVersion> = 2.3>

 WSGIScriptAlias /'C：/ Users / myfolder / Bitnami Django Stack projects / tooltrack / tooltrack / wsgi.py'
 
< DirectoryC： Users / myfolder / Bitnami Django Stack projects / tooltrack / tooltrack> 
选项+ MultiViews

订单允许，拒绝
允许从所有
< / IfVersion> 
< IfVersion> = 2.3> 
要求全部授予
< / IfVersion> 
< / Directory> 
  

由于这一点，我知道它挂在大熊猫的进口上：

  def panda_dataframe_r（）：
 print'importing pandas'+ str（timezone.now（））
 import pandas 
打印'import done'+ str（timezone.now（））
  

我可以看到在日志中导入熊猫，但是没有以下导入完成

任何帮助非常感谢!!

解决方案

尝试添加：

  WSGIApplicationGroup％{GLOBAL} 
  

需要在Python子解释器中不起作用。该指令将强制使用主要的口译员环境。

I've got a Django project working on an Apache server.

I installed pandas and want to use it to start manipulating data - however something odd is happening.

Anytime I use the import pandas on the production environment, the server will hang up and (after a while) throw a 408 timeout error.

I can comment out the pandas portion and the server responds normally without issue. I can't recreate it in the development environment or command line interface with django.

Here are the httpd-app.conf file:

Alias /tooltrack/static "C:/Users/myfolder/Bitnami Django Stack Projects/tooltrack/static/"
<Directory "C:/Users/myfolder/Bitnami Django Stack Projects/tooltrack/static/">
Options +MultiViews
AllowOverride All
<IfVersion < 2.3 >
    Order allow,deny
    Allow from all
</IfVersion>
<IfVersion >= 2.3>
    Require all granted
</IfVersion>

<IfVersion < 2.3 >
    Order allow,deny
    Allow from all
</IfVersion>
<IfVersion >= 2.3>
    Require all granted
</IfVersion> 
</Directory>


WSGIScriptAlias / 'C:/Users/myfolder/Bitnami Django Stack projects/tooltrack/tooltrack/wsgi.py'

<Directory "C:/Users/myfolder/Bitnami Django Stack projects/tooltrack/tooltrack">
Options +MultiViews
AllowOverride All
<IfVersion < 2.3 >
    Order allow,deny
    Allow from all
</IfVersion>
<IfVersion >= 2.3>
    Require all granted
</IfVersion>

<IfVersion < 2.3 >
    Order allow,deny
    Allow from all
</IfVersion>
<IfVersion >= 2.3>
    Require all granted
</IfVersion> 
</Directory>

<Directory "C:/Users/myfolder/Bitnami Django Stack projects/tooltrack">
Options +MultiViews
AllowOverride All
<IfVersion < 2.3 >
    Order allow,deny
    Allow from all
</IfVersion>
<IfVersion >= 2.3>
    Require all granted
</IfVersion>
</Directory>

I know its hanging up on the import of pandas due to this:

def panda_dataframe_r():
print 'importing pandas ' + str(timezone.now())
import pandas
print 'import done ' + str(timezone.now())

I can see the importing pandas in the log, however no following import done

Any help is greatly appreciated!!

解决方案

Try adding:

WSGIApplicationGroup %{GLOBAL}

Various of the scientific packages that it is going to need will not work in Python sub interpreters. That directive will force the use of the main interpreter context.
