AttributeError：模块“ cv2”没有属性“ PCAComputeVar”
[英]AttributeError: module 'cv2' has no attribute 'PCAComputeVar'
问题描述
I was working on a project on facial recognition using asift, which does PCA whitening before it processes the image. 
我当时正在使用asift进行面部识别项目，该项目在处理图像之前先进行PCA白化。 One of my friends downloaded a code and gave it to me for execution, so we have something to start with. 我的一个朋友下载了一个代码并将其提供给我执行，因此我们有一些起点。 But however, on execution, I got an error, which said - 但是，在执行时，我遇到了一个错误，它说-
AttributeError: module 'cv2' has no attribute 'PCAComputeVar'
On Googling, I found that PCAComputeVar is supported mainly in opencv 2. However, I couldn't find anything in opencv 3. I don't want to downgrade to opencv 2, because there are some features supported only in opencv 3. 在Googling上，我发现opencv 2主要支持PCAComputeVar。但是，我在opencv 3中找不到任何东西。我不想降级到opencv 2，因为只有opencv 3支持某些功能。
Is there any method by which I can access opencv 2 libraries from opencv3? 有什么方法可以从opencv3访问opencv 2库？ If not, atleast is there any function in opencv 3, which does something similar to this? 如果没有，则opencv 3中至少有什么功能，这与此类似吗？
