QUESTION
I am trying to make sense of the following presentation, see page 27:
Could someone please describe the command line tools available in libjxl that can help me work with existing palettes ?
I tried a naive:
...ANSWER
Answered 2022-Mar-29 at 15:39The libjxl encoder either takes a JPEG bitstream as input (for the special case of lossless JPEG recompression), or pixels. It does not make any difference if those pixels are given via a PPM file, a PNG8 file, a PNG24 file, an RGB memory buffer, or any other way, if the pixels are the same, the result will be the same.
In your example, you have an image that is just solid white, so it will be encoded the same way regardless of how you pass it to cjxl.
Now if those pixels happen to use only few colors, as will be the case for PNG8 since there can be at most 256 colors in that case, the encoder (at a default effort setting) will detect this and use the jxl Palette transform to represent the image more compactly. In jxl, palettes can have arbitrary sizes, there is no limit to 256 colors. The --palette option in cjxl can be used to set the maximum number of colors for which it will still use the Palette transform — if the input image has more colors than that, it will not use Palette.
The use of Palette is considered an internal encoding tool in jxl, not part of the externally exposed image metadata. It can be used by the encoder to effectively recompress PNG8 files, but by no means will it necessarily always use that encoding tool when the input is PNG8, and it might also use Palette when the input has more than 256 colors. The Palette transform of jxl is quite versatile, it can also be applied to individual channels, to more or less than 3 channels, and palette entries can be not only specific colors but also so-called "delta palette entries" which are not a color but signed pixel values that get added to the predicted pixel value.
QUESTION
Sagemaker pipelines are rather unclear to me, I'm not experienced in the field of ML but I'm working on figuring out the pipeline definitions.
I have a few questions:
Is sagemaker pipelines a stand-alone service/feature? Because I don't see any option to create them through the console, though I do see CloudFormation and CDK resources.
Is a sagemaker pipeline essentially codepipeline? How do these integrate, how do these differ?
There's also a Python SDK, how does this differ from the CDK and CloudFormation?
I can't seem to find any examples besides the Python SDK usage, how come?
The docs and workshops seem only to properly describe the Python SDK usage,it would be really helpful if someone could clear this up for me!
...ANSWER
Answered 2022-Mar-22 at 22:39SageMaker has two things called Pipelines: Model Building Pipelines and Serial Inference Pipelines. I believe you're referring to the former
A model building pipeline defines steps in a machine learning workflow, such as pre-processing, hyperparameter tuning, batch transformations, and setting up endpoints
A serial inference pipeline is two or more SageMaker models run one after the other
A model building pipeline is defined in JSON, and is hosted/run in some sort of proprietary, serverless fashion by SageMaker
Is sagemaker pipelines a stand-alone service/feature? Because I don't see any option to create them through the console, though I do see CloudFormation and CDK resources.
You can create/modify them using the API, which can also be called via the CLI, Python SDK, or CloudFormation. These all use the AWS API under the hood
You can start/stop/view them in SageMaker Studio:
QUESTION
How are U? I'm dealing with this problem: I have two columns with equal width, but in the right columns under the name, appear an extra height so the text are not equal aligned between both columns. I left here the link of the page that I'm working and the code is someone can help me...
---LINK: http://c2260485.ferozo.com/the-team/
...ANSWER
Answered 2022-Feb-21 at 18:40Add align-self: flex-start;
to the second flex container that has the class tt-people-col-2.
That fixes your alignment, then to clean it up a bit, you can add gap: 20px;
on your parent flex-container since you are using flex-wrap: nowrap;
. You will notice the spacing between the two
tags are off, since you are using Bootstrap you can just add some mt
. However, I would nest the text in another div.
QUESTION
I have followed this tutorial to produce a working Cognito authentication solution for my MVC app. However, I need access to the user's JWT token for further custom authentication permissions. I have learned that the /oauth2/token endpoint returns that token. My use case calls for the grant_type
to be authorization_code
, which means that I have to pass a code
parameter to the endpoint. What value needs to be placed there actually? How do I produce it? Alternatively, is there any other way to retrieve/store the JWT anywhere in the application after a user passes authorization?
ANSWER
Answered 2022-Jan-27 at 15:13It turns out the JWT of an authorized user can simply be accessed in the controller as in this solution: Oauth 2.0 How to access the access token saved in AuthenticationProperties , completely allowing us to bypass additional AWS calls.
QUESTION
I have borrowed JavaScript from another source and trying to alter it to fit my needs. I want the parent tab to stay 'active' and the subtabs have a separate 'active' display. This would help keep users aware as to which main tab they are on.
I am working with a vendor platform that has coding restrictions - which is why some of my code might be over styled.
Any assistance is appreciated :)
...ANSWER
Answered 2022-Jan-27 at 13:43Given your actual code an easy way to achieve what you want is handling independently the active
class on tabs and subtabs buttons.
First assign a dedicated class to subtabs buttons, lets say subtablinks

QUESTION
I have a css grid layout that looks like this,
When a box is clicked is grows in height to show information about the service. What I was hoping to be able to do was the "relayout" the grid so grid wrapped around the tallest item? Instead what I have is when I an item grows that row and it's children grow with it.
What I was hoping for was if report writing was clicked it would grow and take up benchmarking space, benchmarking would move left and consultancy would wrap onto a new line?
I am using tailwind so my HTML looks like this,
...ANSWER
Answered 2022-Jan-21 at 17:51A couple of things.
You can make the clicked item span two rows by setting grid-row: span 2
This will have the effect of 'pushing' other grid items around.
In the JS you had a call to remove
which I think should have been removeClass

QUESTION
I am still learning Vuejs and I would really appreciate some help!
This is part of my parent component (a table with iterated workshops in each row). The workshop data is fetched from the db using Vuex.
EditWorkshop is my child component.
I have a button in each row that I can click such that it opens the modal (child component) with information (about the one specific workshop in that particular row) passed from the parent component to the child component through the use of props, and it is called "workshopItem" in the child component.
