kandi X-RAY | ckb Summary
ckb is an informal implementation of the model focusing on the link prediction task inductive entity representations from text via link prediction. this tool allows to train transformers i.e. bert (and all his friends) to build embeddings of the entities of a knowledge graph. the ckb library is dedicated to knowledge bases and allows to fine-tune huggingface models using the link prediction task. the objective of this fine-tuning task is to make accurate embeddings of the knowledge graph entities. the link prediction task aims at training a model to find the missing element of an rdf triplet. for the triplet (france, is_part_of, ?), the model should retrieve the entity europe. after fine-tuning the transformer on the link

hi i have a basic a check box list in my html which is controlled by a script that limits the checks to 4 boxes only . now i need to take only the checked boxes that the user has chosen , i cant seem to get a good idea to take it

QUESTION
I'm modifying the text and CSS of the Google Translate widget and have an error when using addEventListener and querySelector to reapply CSS and text changes after the Google Translate bar is closed and when the page is returned to the original language.
I'm suddenly getting an error Uncaught TypeError: x.X is undefined pointing to the line
x.X.querySelector('select').addEventListener('change', (event) => {
This new error is probably due to a jQuery main library update.
How do I define x.X?

Answered 2021-Mar-24 at 20:23Here logging x you will find querySelector under an object V.
x.V.querySelector('select').addEventListener('change', (event) => {
Fixed this issue on jsfiddle.
But this seems as generated classname so its susceptible to changes.
document.querySelector('select').addEventListener('change', (event) => {

Large json files are available (from 100 MB to 2 GB).
How I can create java (pojo) from json? I need to get the names of all fields. For example, one class can have more than 1000 fields.
Tried the following libraries & online services:
JsonSchema2Pojo works well, but has a limit of about 50,000 characters at a time. Due to the presence of limits, I cannot completely map the class. Need to partially copy the json each time and then remove the duplicate fields.

How do I convert the below java code to equivalent dart.

byte[] data;
System.arraycopy(mIdBytes, 2, data, 0, 4);
Is there any Dart method that does a similar kind of operation?

I have an icon button menu that contains a checkbox list of menuitems. I want to add a title to the menu when the user clicks on the icon and opens the dropdown, at the top of the dropdown with a close button.
What I currently do is use the 1st menuitem and disable it, override the style and display a title. I really hate this, because it's not the way it should be done. Now I want to add a close button to the right side of the tite, but since the menuitem is disabled, I can't do it.
Here's my code:

Menu renders it within a , but it also does some things you don't want -- the main one being that it renders the entire- as a button using the
buttonprop ofListItem.To avoid having the entire
- treated like a button, I would use
ListItemas your starting point (which provides a reasonable starting point for styling).My other suggestion is a bit of a hack that is dependent on implementation details that could change in the future. When
Menuopens it will try to put focus on the first non-disabled menu item (there are ways of modifying this functionality, but for the most part this is desirable). It determines whether a menu item is disabled by looking for adisabledprop on the immediate children of theMenu. So my suggestion is to give your title element thedisabledprop, but to have your customListItemignore that prop.This would look something like this:

I have big complex form, there can be similar checkboxes with the same class or even name. So I need that some of them would restricted from checking more then once. I found good examples how to do that but none of them worked for me. Can someone take a look and say what I'am doing wrong thanks. When pushing green button script generates similar form so i need that checkbox pagrindines would be allowed to select once through all generated forms if there is selected no more can be in other places ofcourse would be great that deselect and changing in another checkbox work.
...ANSWER
Answered 2020-May-31 at 11:42If the checkbox with the name pagrindines1 is added dynamically, you have to delegate the change() event from a static parent element that is already there when the page is initially loaded, e.g. from $(document), using on().

QUESTION
Essentially, this is a repost of this question: https://confluence.ecmwf.int/pages/viewpage.action?pageId=149341027
I have downloaded ERA5 from the CDS. The input file has 24 hourly steps (0, 1, 2, 3, 4,..,23) for each calendar day starting from Jan 1 to Dec 31 of each considered year.
ECMWF state here https://confluence.ecmwf.int/display/CKB/ERA5%3A+How+to+calculate+daily+total+precipitation that daily total precipitation must be calculated by accumulating precipitation for e.g. Jan 1, 1979 by summing the steps 1, 2,...,23 of Jan 1 AND step 0 of Jan 2. It means that the step 0 of Jan 1, 1979 is not included in calculation of the total precipitation for that day. For calculation of total precipitation for Jan 2, 1979 we use also the steps 1, 2, 3,...,23 of that day plus step 0 of Jan 3 and so on.
There seems to be an option doing this in python like this:
...ANSWER
Answered 2020-Feb-01 at 10:05For these kind of issues, the useful command in CDO is shifttime, which essentially does what is says on the can and shifts the time stamp.
This kind of problem arises frequently with any kind of flux or accumulated field where the timestamp allocated to the data value points to the END of the time accumulation period, or "window", for example, with 3 hourly TRMM data the last three hours of the day have the stamp of 00 on the date afterwards, and functions such as daymean or daysum applied directly will calculate the average of 21 hours in one day and 3 hours from the previous day, incorrectly. Shifting the timestamp by three hours so the time points to the start of the window (or indeed by 1.5, pointing to the middle) before you perform the calculation will resolve this.
So for your specific question where you have a long series of hourly data from ERA5 and you want the daily total, you can do:
