Python web2py导入matplotlib模块失败

我不太了解web2py的

custom\u import.py

的工作原理。我试图从withing

mathplotlib

导入模块，但结果不一致

我的控制器

version.py

包含这些语句

def import_mathlab_cbook():
    import matplotlib.cbook as cbook
    return "cbook.__file__ = %r" % cbook.__file__

def import_mathlab_figure():
    from matplotlib.figure import Figure
    return "Figure.__file__ = %r" % Figure.__file__

def import_mathlab_backends():
    from matplotlib.backends.backend_agg import FigureCanvasAgg 
    return "FigureCanvasAgg.__file__ = %r" % FigureCanvasAgg.__file__

matplotlib.cbook的导入工作正常，但其他导入会产生错误

cbook.__file__ = '/opt/anaconda2/lib/python2.7/site-packages/matplotlib/cbook.py'

Traceback (most recent call last):
  File "/site/web2py.2.13.4/gluon/restricted.py", line 227, in restricted

    return base_importer(pname, globals, locals, fromlist, level)
ImportError: No module named matplotlib.figure

我正在运行

Python 2.7.11 | Anaconda 2.4.1（64位）|（默认值，2015年12月6日，18:08:32）

和web2py

Version 2.13.4-stable+timestamp.2015.12.26.04.59

我知道有一个类似的问题，但是这个问题的答案还没有被接受。

我还尝试复制web2py应用程序模块目录下的

matplotlib

目录，但是我得到了

importorror:libpng16.so.16:无法打开共享对象文件：没有这样的文件或目录

。什么是

cbook.\uuuuu file.\uuuuu

和

matplotlib.figure.\uuu file.\uuuuuu

在命令行导入中，它们只是用来演示文件从何处导入。这些方法是为诊断目的而编写的。原始代码在文件开头只有3条导入语句。我认为这可能有助于其他人分析您的问题。我还尝试复制web2py应用程序模块目录下的
