PHP和导入pylab [英] PHP and Importing pylab

问题描述

我有一个调用python程序的PHP脚本。这是php脚本：

I have a PHP script that calls in a python program. Here is the php script:

<?php
    $last_line = popen('/Library/Frameworks/Python.framework/Versions/Current/bin/python test.py', 'r');
    $results = fgets($last_line);
    print $results;
?>

这是test.py的内容：

and this is the content of test.py:

test.py:

    import numpy as np
    from matplotlib.patches import Ellipse
    # import matplotlib.pyplot as plt
    # from matplotlib.pyplot import figure, show
    # import pylab 

    print "Hello World!"

现在，这个工作正常，我得到Hello World！在浏览器中。但是，如果我取消注释任何导入（即，将matplotlib.pyplot导入为plt，将matplotlib.pyplot导入为plt或导入pylab），我不会从PHP获得结果。如果有人可以帮我解决这个问题，那就太好了，因为我需要Python中的所有绘图函数。

Now, this works fine and I get "Hello World!" in browser. However, if I uncomment any of the imports (i.e., import matplotlib.pyplot as plt, import matplotlib.pyplot as plt or import pylab) I don't get the result from PHP. It will be great if someone could help me with this as I need all the plotting functions from Python.

推荐答案

matplotlib部分是当python脚本通过php执行时没有执行。
然后我只在我的.py文件中包含以下语句..

The matplotlib part was not getting executed when the python script was executed through php. Then i just include the following statements in my .py file..

import os
os.environ[ 'MPLCONFIGDIR' ] = '/tmp/'

import matplotlib

matplotlib.use('agg')

它有效......
