我花了几个小时试图运行这个脚本，但由于某种原因它根本无法正常运行。'Sex' 现在是一个全球性的安装，所以它说得很好，但其他东西似乎失败了。不幸的是，看起来它失败的东西是它应该创造的东西。我什至在 def 语句之后添加了一个简单的打印语句，它不会打印，它只是自动失败。有什么见解吗？

代码：

def objmask(inimgs, inwhts, thresh1='20.0', thresh2='2.0', tfdel=True, 
            xceng=3001., yceng=3001., outdir='.', tmpdir='tmp'):
    print "c"
# initial detection of main galaxy with SExtractor for re-centering purposes
    if outdir!='.':
        if not os.path.exists(outdir):
            os.makedirs(outdir)
    print inimgs

    if not os.path.exists(tmpdir):
        os.makedirs(tmpdir)
    for c in range(np.size(inimgs)):
        print 'Creating Aperture Run:', c
        subprocess.call(['sex',inimgs[c],'-c','/home/vidur/se_files/gccg.sex',
                         '-CATALOG_NAME','/home/vidur/se_files/tmp'+str(c)+'.cat',
                         '-PARAMETERS_NAME','/home/vidur/se_files/gccg_ell.param',

                         '-VERBOSE_TYPE','QUIET',
                         '-DETECT_THRESH',thresh1,
                         '-ANALYSIS_THRESH',thresh2,
                         '-WEIGHT_IMAGE',inwhts[c]],shell=True
                         )

错误：

错误中最相关的部分似乎是结尾。
