...ANSWER
Answered 2022-Mar-31 at 13:30Array is not a type class, but a type.
You accidentally put a fat arrow after Array a instead of a thin arrow, making it look like you were declaring a value of type Int with a constraint Array a rather than a function that takes an Array a as a parameter and returns an Int. This is how it should look:
QUESTION
I'm trying to use Sentence Transformers and Haystack for document retrieval, focusing on searching documents on other metadata beside document text.
I'm using a dataset of academic publication titles, and I've appended a fake publication year (which I want to use as a search term). From reading around I've combined the columns and just added a separator between the title and publication year, and included the column titles since I thought maybe this could add context. An example input looks like:
title Sparsity-certifying Graph Decompositions [SEP] published year 1980
I have a document store and method of retrieving here, based on this:
...ANSWER
Answered 2022-Mar-26 at 10:57It sounds like you need metadata filtering rather than placing the year within the query itself. The FaissDocumentStore doesn't support filtering, I'd recommend switching to the PineconeDocumentStore which Haystack introduced in the v1.3 release a few days ago. It supports the strongest filter functionality in the current set of document stores.
You will need to make sure you have the latest version of Haystack installed, and it needs an additional pinecone-client library too:

QUESTION
as the title suggests I'm trying to parse a piece of code into a tree or a list. First off I would like to thank for any contribution and time spent on this. So far my code is doing what I expect, yet I am not sure that this is the optimal / most generic way to do this.
Problem 1. I want to have a more generic solution since in the future I am going to need further analysis of this sintax. 2. I am unable right now to separate the operators like '=' or '>=' as you can see below in the output I share. In the future I might change the content of the list / tree from strings to tuples so i can identify the kind of operator (parameter, comparison like = or >= ....). But this is not a real need right now. ResearchMy first attempt was parsing the text character by character, but my code was getting too messy and barely readable, so I assumed that I was doing something wrong there (I don't have that code to share here anymore) So i started looking around how people where doing it and found some approaches that didn't necessarily fullfil the requirements of simplicity and generic. I would share the links to the sites but I didn't keep track of them.
The Syntax of the code The syntax is pretty simple, after all I'm no interested in types or any further detail. just the functions and parameters. strings are defined as 'my string', variables as !variable and numbers as in any other language. Here is a sample of code:

QUESTION
I'm writing an image detection bot and as per the advice from a few members, I refactored some code and separated this section into its own function objectDetection I'm trying to do two things with the array image_list
- Iterate through the array and if any image is detected I want to immediately print "Avoided" to the terminal and restart the
objectDetectionfunction from the beginning of the array.
I've tried to do this with the flag variable found_anything = True and break it hasn't worked.
- Iterate through the full array of images and if nothing at all is found, execute
functionTwo()
I tried to do this with the break at the end of my for i in image_list: loop, it also hasn't worked.
So far I've tried....
Reading through these three pages: Break out of two loops and two if statements - Python break out of two loops without disturbing the if statements after it in python Accessing the index in 'for' loops? and I tried both the variable flags and break statements but I can't get either to work.
I also had a look at this: How to break out of multiple loops? but what is the difference between return and break in python? made me think in my case the top answer wouldn't be appropriate as I don't think I'm returning data outside of my function.
Is there a way I can adapt this code to achieve my two uses cases above? Am I missing something obvious? I've been thought all the loop tutorials I can find and I'm still struggling, is this simply a difficult way I'm trying to design things? Or am I simply not getting it and should go back over some tutorials.
...ANSWER
Answered 2022-Feb-10 at 10:49I'd refactor the whole thing but something like this answers the main question: Refactor your functions such that you can use 'Return' instead of 'Break'
QUESTION
Please consider this question.
I need to parameterize a SQL (sub) query in golang. Please consider the pseudo-code below or at https://go.dev/play/p/F-jZGEiDnsd
The hayStack details come to me in an string slice lookIn and can vary. I need to search for %eedl% (needle) in all these haystacks.
The code in the comment is how I currently handle it - I only parameterize the needle I am looking for.
How do I parameterize the hayStacks as well?
ANSWER
Answered 2022-Feb-10 at 07:00Using just the standard library you can collect the haystack arguments and the needle argument into a single slice and then pass that to the Query method.
For the SQL itself you can use the IN operator and generate its right hand side operand as a list of ? based on the number of haystacks.
