Question

我不太了解web2py custom_import.py的运作方式。我正在尝试从mathplotlib导入模块，但结果不一致。

我的控制器version.py包含这些陈述。

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，但其他导致错误。

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
    exec ccode in environment
  File "/site/web2py.2.13.4/applications/plotlab/controllers/version.py", line 53, in <module>
  File "/site/web2py.2.13.4/gluon/globals.py", line 412, in <lambda>

    from matplotlib.figure import Figure
  File "/site/web2py.2.13.4/gluon/custom_import.py", line 95, in custom_importer
    return base_importer(pname, globals, locals, fromlist, level)
ImportError: No module named matplotlib.figure

所有这些import语句都可以在命令行中运行，并且在命令行运行web2py时。

我正在运行Python 2.7.11 |Anaconda 2.4.1 (64-bit)| (default, Dec 6 2015, 18:08:32)和web2py Version 2.13.4-stable+timestamp.2015.12.26.04.59.39。

我知道有一个关于importing the copy_reg module的类似问题，但是对于这个问题尚未接受答案。
