Hello.

I have 2 questions

1. I want to store arrays of images obtained from numpy (Python) Arrays, for example, are as follows: [1.1, 2.2, 3.3, 4.4, 5.5, 6.6] How can they be indexed?
2. Let's say they are indexed. We have an array [1.2, 2.4, 3.5, 4.9, 5.0, 6.7] It's not in the index. But we need to get as similar to it. Ideally, when you request to receive multiple responses of the form:
3. 
  - array
  - the number of Euclidean distance

4. 
  - array
  - the number of Euclidean distance

5. 
  - array
  - the number of Euclidean distance

like nearest neighbors

Something similar is announced in future versions. But I would like to know if there are any solutions now? The plug-ins? Thank you advance
