如何在Amazon Elastic Beanstalk上安裝opencv-python

Question

我一直在本地開發Python應用程序，現在想將它部署到Amazon Elastic Beanstalk，但是我遇到了以下錯誤：

Downloading/unpacking opencv-python==2.4.8.1 (from -r
/opt/python/ondeck/app/requirements.txt (line 12))  
Could not find any downloads that satisfy the requirement opencv-python==2.4.8.1
(from -r /opt/python/ondeck/app/requirements.txt (line 12))

Some externally hosted files were ignored (use --allow-external opencv-python to allow). 
Cleaning up... No distributions at all found for opencv-python==2.4.8.1 
(from -r /opt/python/ondeck/app/requirements.txt (line 12))

如果我用SSH連接並輸入sudo pip install opencv-python它會說“下載/解壓縮opencv-python”一分鍾左右，那么：

Could not find any downloads that satisfy the requirement opencv-python
Cleaning up...
No distributions at all found for opencv-python
Storing debug log for failure in /root/.pip/pip.log

我也嘗試在我的要求中添加“ http://rpmfind.net/linux/fedora/linux/development/rawhide/x86_64/os/Packages/o/opencv-python-2.4.9-3.fc22.x86_64.rpm ” .txt但失敗如下：

Cleaning up...

我也試過“sudo yum install opencv-python”，但失敗如下：

Loaded plugins: priorities, update-motd, upgrade-helper

No package opencv-python available.
Error: Nothing to do

對於我的開發系統，我從http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv獲得了安裝程序。 我怎樣才能在EB上安裝它？

如果沒有辦法安裝這個確切的包裝，請問最好的選擇是什么？

Answer 1

如果您能夠考慮變通方法，可以使用以下選項。

使用AWS Elastic Beanstalk

• AWS EB支持Windows Server 2012和2008

  由於您的安裝程序似乎是Windows可執行文件，因此您可以考慮在Windows上進行部署。 https://aws.amazon.com/net/

• 使用Docker將Fedora平台打包，以便在EB的AMI Linux主機上運行。

  Elastic Beanstalk支持Docker。
  http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_docker.html

  下面是python上opencv的Docker構建文件示例。 https://registry.hub.docker.com/u/ibotdotout/python-opencv/

沒有AWS Elastic Beanstalk

• 其他Linux發行版

  如果你不是絕對需要Elastic Beanstalk，那么運行Fedora呢？ 這些安裝說明很簡單。

  http://docs.opencv.org/trunk/doc/py_tutorials/py_setup/py_setup_in_fedora/py_setup_in_fedora.html （基本上是yum install numpy opencv *）

  您可以在沒有Elastic Beanstalk的情況下使用EC2。

Answer 2

現在簡單的解決方法是安裝pip 1.2.1，它不需要SSL：

curl -O https://pypi.python.org/packages/source/p/pip/pip-1.2.1.tar.gz
tar xvfz pip-1.2.1.tar.gz
cd pip-1.2.1
python setup.py install

也許這可以幫到你

Answer 3

我在Ubuntu 14.04的專用實例上運行OpenCV，在Amazon EC2上支持Python。 我必須從源代碼安裝和編譯才能獲得可靠的python堆棧。
