Can someone please explain how slicing works in following statements?

1. bbox[:, [0, 2]] = width - bbox[:, [2, 0]]

*width is the width of a 2D image

What is the role of [0,2] in the above statement?

1. iw = (torch.min(boxes[:, 2:3], query_boxes[:, 2:3].t()) - torch.max(boxes[:, 0:1], query_boxes[:, 0:1].t()) + 1).clamp(min=0)

What is the role of 2:3, or 0:1 in the above statement?

Thanks!

I’m trying to integrate spark(3.1.1) and hive local metastore (3.1.2) to use spark-sql.

i configured the spark-defaults.conf according to https://spark.apache.org/docs/latest/sql-data-sources-hive-tables.html and hive jar files exists in correct path.

but an exception occurred when execute 'spark.sql("show tables").show' like below.

any mistakes, hints, or corrections would be appreciated.

I want to upload the video/audio file in my django-channels project. So I uploaded video(base64 encoded url) from websocket connection. It is working fine. But now after decoding base64 video data I want to compress that video using ffmpeg.But it showing error like this. ''Raw: No such file or directory'' I used 'AsyncJsonWebsocketConsumer' in consumers.py file.Here is my code: consumers.py:

so i found this snippet of code that lets you filter markers when you select them from dropdown, the code actually works if i take out the radio buttons from the dropdown and click them, but if i put them back in an actuall dropdown menu, it doesnt filter the markers, it just stays how it is. I want them to work like this - if i Select Rīga from the dropdown, only show markers that have it as marker[4].

I needed to use binary search on an array to find their indexes. I was able to do that, however I now need to use Objects with the array being of type Integer instead of int.

Here's the question : "Supply the code for the binarySearch method remembering that the parameters it receives are Object type objects, and if either is used to call the compareTo method, it must first be cast as a Comparable or original object type."

I would really appreciate if I got some more info on this if not the code for it. The question confused me a bit.

this is the type of data passed to the binary search method.

i'm using liferay 7.3.5 und try to creat an elasticSearch. Through my first experience in ElasticSearch, I tried to index one of the entities I have in the database. I built the search platform properly and work with in remote mode within a specific node. For indexing I have followed the steps one by one in this tutorial

Creating a Guestbook Indexer

Also Index handling in the service layer did it as well and it works fine and in debug mode this can be seen clearly, entries are indexed, converted into documents, and stored in the special index number that corresponds to the companyId in Liferay.

I can see that index in the local host in the search menu.

The problem is that when I search within the generated index using Kibana or direkt in elasticsearch, I do not find my own entries.

Here is my elasticsearch config.

I want to break one of my "for" loop once it returns empty "link".

I am attempting to create a 2D array from another, by taking the sum of NxN pixels around a point on the image, and saving the result at the same coordinate in the new image:

I am doing a project that needs iwlib. On my PC it works fine but I cannot add my project to Yocto. I get error No such file or directory. I have tried to add iw to the image and to DEPENDS variable in my project recipe file but it seems doesn't work. I get still the same error. I used to thought that the iw files were installed in another path that on my PC, so I have built the image with iw but without my app and next I have used find -iname to find this file in all my Yocto repositiry but I didn't find it.

Do you have any idea how to add iw package to Yocto? Thank you in advanced for any help.

EDIT: The error:
