kandi X-RAY | CWR Summary

CWR is a Python library typically used in Artificial Intelligence, Computer Vision, Deep Learning, Pytorch applications. CWR has no bugs, it has no vulnerabilities, it has build file available and it has low support. However CWR has a Non-SPDX License. You can download it from GitHub.

We provide our PyTorch implementation for paper "Single Underwater Image Restoration by Contrastive Learning". CWR is designed for underwater image restoration, but not limited to it. It performs style-transfer to certain kinds of low-level vision tasks (e.g. Dehaze, Underwater image enhancement, Deraining) while keeping the structure identical. CWR achieves SOTA performances in underwater image restoration task using HICRD (Heron Island Coral Reef Dataset) as the training data.

I am working on a Boids project, details of which can be found here:

From what I can gather my issue is something to do with an index getting accessed by the function but no data is present in the index. I had this issue yesterday in a different area of my code and fixed it by making one of my getters return a reference rather than a copy of a class object. That approach seems to not be the issue today.

Below is my code:

I see nothing in this code that can cause an out of bounds access. However, you should not increment i on any loop iteration that removes an organism, otherwise you will skip the next organism in the list.

Imagine on the 1st loop iteration, the organism at index 0 needs to be removed. Subsequent organisms move down the list. On the next loop iteration, i gets incremented to 1, and the organism that had moved into index 0 is skipped.

Try this instead:

I need to make a conversion table that essentially says if variable 1 is in this range and variable 2 is in this range then variable 3 = x. I've done this in PHP and it works, however for my current project PHP won't work. Is there another straight forward way to accomplish this via Java or something? If anyone could just steer me in the right direction that'd be great!

Answered 2020-Jun-15 at 21:51

As suggested above, there is a much more efficient method to achieve this functionality. Rather than creating a new array with range() each time, we can simply test if the variable is within two bounds.

QUESTION

NullReferenceException when accessing an IEnumerable of a custom class

Asked 2020-May-05 at 15:48

Goal

I am designing a boid system using Unity. I deal with the awareness radius by adding a boid to the "Swarm" list when it enters a collider. In order to find the force for each boid, I need to cycle through the swarm list, access the "Boid" class, and retrieve velocity and position.

Problem

The Boid classes from each swarm entity are added to a new list, and passed to the physics controller. However, a NullReferenceException is thrown at line 96, and I don't understand why that variable would be null. As far as I know, accessing a populated Enumerable using foreach should have variables within.

NullReferenceException: Object reference not set to an instance of an object Boid.Alignment (System.Collections.Generic.IEnumerable`1[T] boids) (at Assets/Scripts/Boid.cs:96) Boid.Update () (at Assets/Scripts/Boid.cs:42)

After testing, it seems it is thrown when accessing any part of the new list of Boids.

Why does my new list contain no data? Is there a better way to handle a 2D implementation of boids in a 3D space? Is there a resource I can use to better understand Linq?

P.S. I am very new to using Linq systems, and most of this code is taken from this video and this Unity project script

Code ...

ANSWER

Answered 2020-Apr-30 at 19:42

Turns out I was assigning null data, because the GetComponent function at line 40 found the "Body" of the boids, which did not have a Boid script attached. When searching with GetComponentInChildren, the array is populated and values are given.

The Old Line:

IEnumerable boids = swarm.Select(o => o.GetComponent()).ToList();

The New Line:

IEnumerable boids = swarm.Select(o => o.GetComponentInChildren()).ToList();

After some search i found the solution.

refer to wireshark wiki:

By default Wireshark and TShark will keep track of all TCP sessions and convert all Sequence Numbers (SEQ numbers) and Acknowledge Numbers (ACK Numbers) into relative numbers. This means that instead of displaying the real/absolute SEQ and ACK numbers in the display, Wireshark will display a SEQ and ACK number relative to the first seen segment for that conversation.

all sequence numbers always start at 0 for the first packet seen in each conversation, so my output wasn't wrong :)

You seem to be close to solution, everything you need is to group consecutive ranges. Because you use Oracle 12 and outer apply, I cannot correct your original query (I have 11g). So I wrote something similar:

The problem you've encountered is Range.Areas. In your case, the .SpecialCells function has created a number of Areas and one or more of those areas overlap. For example, if any of your rows had an error in more than one column, then you'd have overlapping areas (ie two or more areas all containing the same row). You cannot run a Delete method on overlapping areas.

There are many ways to deal with this issue, but a simple one-liner would be to Intersect the sheet's cells with your range. That kind of coerces Excel to remove overlaps.

So your last line could simply be:
