kandi X-RAY | composition Summary
Composition provides a lightweight and generic API, that you can use to check your environment at runtime, instead of manually go checking for regex in constants, classes/functions existence, matching a version against a class constant, ... It only works when using Composer as package management tool.

QUESTION
Hey to all in the forum
I use JSF Mojarra implementation, version JSF 2.2
I need desperately a help on this.
- I have a snippet of my page.
- I have a custom component "example_result.xhtml" used in the page.
- I have my BackingBean.java Be aware please that this code is not the real code I made. If you run it, it will be very ugly maybe because I deleted all the css classes and I kept only the hot stuff I need to show you my problem.
Everything is inside 1 form.
The 5 "h:selectManyCheckbox" (in my code I have 8 or 9)
In the form I have 5 "h:selectManyCheckbox" which are using values in the "value" attribute for different cases (javaFrameworks2Values, javaFrameworks3Values,...), and the "f:selectItems" use arrays of "SelectItem" (javaFrameworksSelectItems2, javaFrameworksSelectItems3...) created for these different cases, just to make some examples for me to understand how all the selectOne and selectMany components work. The ideas for this, about different cases were taken from these links: "https://stackoverflow.com/tags/selectonemenu/info" and "https://mkyong.com/jsf2/jsf-2-checkboxes-example".
After I have 2 commandButtons
1 for submit, and 1 for reset the values.
Display the values
After I display the results of the values of the "h:selectManyCheckbox" via the "example_result.xhtml".
You can see the 4th "h:selectManyCheckbox" that is the only one different, because it has the attribute "required" with the attribute "requiredMessage". With it there is a "h:message" to display the validation error.
In the BackingBean (which is Spring Bean, but it works perfectly good - sorry I don't want ejbs 3.x), I have initialized:
- The values of the SelectItems and
- The values of the "value" attribute, where the values of the "h:selectManyCheckbox" will be stored to be displayed later. [The code is completely castrated, to make it readable snippet].
When the page is rendered, I select checkBoxes (e.g. the 2 last, because the 2 first are initials) from all the "h:selectManyCheckbox". When I say that select from all, I mean it. And from the 4th with the "required" attribute. I try in the buttons (see in the code) the "Effort 1", or "Effort 2", or "Effort 3" (in the "f:ajax" in the buttons) and the result outputs in the last part are displayed and updated like a candy. Without any problem. To achive this with the composite component I googled and tried a lot. But I made it.
Then it comes the time to try the 4th to see the validation error of the "required" attribute.
I select again from all as before, but not from all. NOT from the 4th "h:selectManyCheckbox" this time. I select nothing from the 4th "h:selectManyCheckbox" to ckeck the validator error message ("requiredMessage"). The result is: It displays the message of error (GOOD until now), BUT this time it does not update anything from the others "h:selectManyCheckbox" to the output results at the end, and it does not reset the values as well as it was doing before (when I selected from all and from the 4th as well).
I understand that it says: as long as in the form the 4th failed with validation error, all the other "h:selectManyCheckbox" will not update the output results (something like wanting to fail all the others too).
But what really happes here?
- It does not give the values to the "h:selectManyCheckbox", to be updated to the output?
- It gives the vales to the "h:selectManyCheckbox" normally, BUT it just not updates the output?
The other efforts in the "f:ajax" in the buttons, are just efforts maybe to solve the problem but in these cases they don't even display the error message in the 4th case and of cource they don't update the other output results as well (again). But no message error as well.
I don't know if the problem is clear to you. I can explain in the discussion better so I can clarify the situation better. [To be honnet it took me 1 and half hour to write all this thing]
Thanks a lot in advance

Answered 2021-Jun-15 at 14:11After a lot of discussing with the only person who wanted to help to my issue here (and I thank him @WoAiNii for this a lot), I decided to post my solution:
I will make 5 different forms with 5 set of buttons (submit/reset), to make escalate this problem, for 5 so much related components in the form.
But my question is open: Why this is happening, what rule in JSF in this case is taking place and makes this situation. Anyone, comes with an explanation:
- Thomas: this is a rule in JSF, or
- is a JSF bug, or
- this happens in these cases, or... whatever...,
I will be glad to read it here so I will learn better, and others to will learn from these ideas of yours. Thanks a lot

In this challenge, using javaScript you will create 3 classes
- Super class called
Animal. DogandCatclass which both extendsAnimalclass (a dog is an animal and a cat is an animal)DogandCatclass should only have 1 function, which is their own implementation of thesound()function. This is polymorphism- a
Homeclass. But we’ll talk about that later
ANSWER
Answered 2021-Jun-05 at 13:48Since 2015 there should be no more need to go through the pain of assigning prototype properties like that, and establish inheritance between two classes with such assignments.
I would suggest rewriting your code completely, and using the class syntax, where you don't need to explicitly do this inheritance fiddling with the prototype property:
QUESTION
Dear Stackoverflow community, I have an excel file "big_excel.xlsx", which comprises of four columns namely "date_column","efficacy", "composition" and "testgroups". Basically, I have splitted this excel quarterly "q1..q4", so that I can compare values in each column with 4 different excels that I recieved from 4 different sources which are supposed to be 100% identical. This excels from sender are such that elements are already sorted in such way that it should match exactly with the excel which are splitted quarterly. My code works perfectly for quarter q1. And to compare I have used ".equals" because it can have nans. Now I have to apply same code concept for the remaining quarters q2..q4.

Answered 2021-Jun-12 at 14:26One approach could be defining a function which takes one quarter dataframe and the corresponding test dataframe for that quarter and returns the original dataframes with the comparing columns. Something like:

I am using Vue3/Vuex 4/TypeScript.
I am trying to access my typed store from within my component (App.vue).

Answered 2021-Jun-11 at 23:52Your syntax for installing the Vuex instance to your app is a little off. You can only install one Vue plugin to an app in each call to use, so combining router, store, key like that doesn't work. As such, Vuex isn't getting installed at all.

After reading documentation of Vee Validate 4 about using composition api with custom inputs, do I understand correctly that hook useField a have to call only inside input component(in my example is VInput.vue)? Is any way that i can use hook functionality in parent component?

Answered 2021-Jun-10 at 11:35I am not sure if understood your question correctly.
But in your case you only have 1 issue, you destructure errorMessage and value twice in one file, which isn't working.

QUESTION
I've found following docker composition:
...ANSWER
Answered 2021-Jun-09 at 10:30On modern Docker I'd never use this pattern, and in particular I'd avoid volumes_from:.
volumes_from: has the two problems of not being clear of what exactly it's mounting and not having any control over where it gets mounted. If the image for your backup had a VOLUME declaration in its Dockerfile, for example, that volume would get mounted in your cron container at the exact same path as in the backup container, even though it's not listed in this docker-compose.yml anywhere. That can lead to surprising outcomes.
Docker didn't always have named volumes. Before there were named volumes, the way to get persistent sharable storage was to create a data volume container that created an anonymous volume, and then run other containers with docker run --volumes-from ... to attach that storage. Now that named volumes exist, there's not a need to do that any more.

QUESTION
I am building a model in pytorch with multiple networks. For example let's consider netA and netB. In the loss function I need to work with the composition netA(netB). In different parts of the optimization I need to calculate the gradient of loss_func(netA(netB)) with respect to only the parameters of netA and in another situation I need to calculate the gradients wrt the parameters of netB. How one should approach the problem?
My approach: In the case of calculating the gradient wrt the parameters of netA I use loss_func(netA(netB.detach())).
If I write loss_func(netA(netB).detach()) it seems that the both parameters of netA and netB are detached.
I tried to use loss_func(netA.detach(netB)) in order to only detach the parameters of netA but it doesn't work. (I get the error that netA doesn't have attribute detach.)
ANSWER
Answered 2021-Jun-08 at 05:14The gradients are properties of tensors not networks.
Therefore, you can only .detach a tensor.
You can have different optimizers for each network. This way you can compute gradients for all networks all the time, but only update weights (calling step of the relevant optimizer) for the relevant network.

PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
