Python 在Powershell中使用CV2和Skimage时出现内存错误

因此，我有一个python脚本，它使用CV2和Skimage比较文件路径中的所有图像，并返回最接近的匹配。它已经过测试，可以工作了

import os
from skimage.metrics import structural_similarity as ssim
import cv2
from shutil import copyfile

def Compare_Images(testDir, reference):

    os.chdir(testDir)
    testlist = os.listdir(testDir)

    smax = 0

    closest = 'null'
    '''s = ssim(imageA, imageB)'''

    for i in range(len(testlist)):

        Reference = cv2.imread(reference)
        Check = cv2.imread(testlist[i])

        Reference = cv2.cvtColor(Reference, cv2.COLOR_BGR2GRAY)
        Check = cv2.cvtColor(Check, cv2.COLOR_BGR2GRAY)

        s= ssim(Reference, Check)
        if (s>smax):
            smax = s
            closest = testlist[i]

    NewPath = "C:\Localdata" + "\\" + closest
    OldPath = testDir + "\\" + closest        
    copyfile(closest, NewPath)
    print (closest)
    return closest

然后，我将其修改为从powershell脚本调用（通过为TestDir设置等于sys.argv[1]的输入参数，为引用设置等于sys.argv[2]）：

但是，当我从Powershell调用它时，会出现以下错误：

    python : Traceback (most recent call last):

+ python $arg3 $arg1 $arg2

如何解决这个问题？

问题是我在Spyder中测试了它，Powershell试图在32位python中运行它。卸载32位python和安装64位python解决了这个问题。

这是完整的错误消息吗？此外，变量和函数名称应遵循带有下划线的

小写形式。使用完整错误更新。您可以共享所有相关代码和数据吗？请看：。对不起，我刚刚添加了我所有的。图片由该公司分类，但python代码有效。任何JPG文件都可以代替它们。你做过分析吗？
