QUESTION
Previously, I was using the python_callable parameter of the TriggerDagRunOperator to dynamically alter the dag_run_obj payload that is passed to the newly triggered DAG.
Since its removal in Airflow 2.0.0 (Pull Req: https://github.com/apache/airflow/pull/6317), is there a way to do this, without creating a custom TriggerDagRunOperator?
For context, here is the flow of my code:
...ANSWER
Answered 2021-Jun-11 at 19:20The TriggerDagRunOperator now takes a conf
parameter to which a dictinoary can be provided as the conf object for the DagRun. Here is more information on triggering DAGs which you may find helpful as well.
EDIT
Since you need to execute a function to determine which DAG to trigger and do not want to create a custom TriggerDagRunOperator
, you could execute intakeFile()
in a PythonOperator
(or use the @task
decorator with the Task Flow API) and use the return value as the conf
argument in the TriggerDagRunOperator
. As part of Airflow 2.0, return values are automatically pushed to XCom within many operators; the PythonOperator
included.
Here is the general idea:

i use parrot security as my daily distro. its mate terminal is transparent so is vim .but i wanted to get auto complete and used some plugins.auto complete window appears to be in pink which looks really ugly in semi transparent black background.i changed the theme and it was fixed but so was gone vim transparency .
in short word (1)i have to keep the default (2)i have to keep transparent vim (3)i have to change the auto complete window from pink to semi transparent black
here is my init.vimrc
...ANSWER
Answered 2021-Jun-09 at 19:27If you are using neovim there is an option called :h pumblend
which can be used to change the transparency of the popup menu.
Are you sure gruvbox
caused your vim to lose transparency? I am not sure if vim is able to change a terminal emulator's transparency. I or someone else might be able to advise you better if you post pictures of what has changed.

mapping is not appropriate. You need to use routineAssignament

relationship.
QUESTION
Good afternoon, comrades. I am sure that no one helped me, tk. I just asked the question not very correctly earlier. I am trying to create a FlexDashcoard application. To understand how the program works, you need the sample data files that I have prepared. I apologize in advance for the Russian characters in the files, they are presented to you "as is".
Here is my code:
...ANSWER
Answered 2021-May-14 at 23:38Unfortunately, there was no one to help me and, after spending many hours, I managed to solve the problem. I sincerely hope that someone will find it useful someday.
My first mistake was using the observeEvent
. If you refer to the description on the official website, you can read the following information:
"Use observeEvent whenever you want to perform an action in response to an event. (Note that "recalculate a value" does not generally count as performing an action--see eventReactive for that.) The first argument is the event you want to respond to, and the second argument is a function that should be called whenever the event occurs.
Use eventReactive to create a calculated value that only updates in response to an event. This is just like a normal reactive expression except it ignores all the usual invalidations that come from its reactive dependencies; it only invalidates in response to the given event."
Thus, in my code, I need to replace observeEvent (input $ dir_choose, {
with rv_result <- eventReactive (input $ apply, {
. You will also need to make the assignment of the final result at the end of this function: rv_result <- rv$txt_file
In the block ### Basic information
, then it becomes possible to call a function and assign the result to a variable: dataset <- reactive({rv_result()})
. And this is the solution to the first part of the question, when after importing the values, it becomes possible to manipulate them.
The second part of the question was how to use selectInput
to control the output table with data.
Everything looks pretty complicated, but the bottom line is that selectInput
after selecting elements indicates a list of values and you can check and compare 2 lists. Accordingly, the code that manipulates the table looks like this:

QUESTION
I’m currently trying to train a Spanish to English model using yaml scripts. My data set is pretty big but just for starters, I’m trying to get a 10,000 training set and 1000-2000 validation set working well first. However, after trying for days, I think I need help considering that my validation accuracy goes down the more I train while my training accuracy goes up.
My data comes from the ES-EN coronavirus commentary data set from ModelFront found here https://console.modelfront.com/#/evaluations/5e86e34597c1790017d4050a. I found the parallel sentences to be pretty accurate. And I’m using the first 10,000 parallel lines from the dataset, skipping sentences that contain any digits. I then take the next 1000 or 2000 for my validation set and the next 1000 for my test set, only containing sentences without numbers. Upon looking at the data, it looks clean and the sentences are lined up with each other in the respective lines.
I then use sentencepiece to build a vocabulary model. Using the spm_train command, I feed in my English and Spanish training set, comma separated in the argument, and output a single esen.model. In addition, I chose to use unigrams and a vocab size of 16000
As for my yaml configuration file: here is what I specify
My source and target training data (the 10,000 I extracted for English and Spanish with “sentencepiece” in the transforms [])
My source and target validation data (2,000 for English and Spanish with “sentencepiece” in the transforms [])
My vocab model esen.model for both my Src and target vocab model
Encoder: rnn Decoder: rnn Type: LSTM Layers: 2 bidir: true
Optim: Adam Learning rate: 0.001
Training steps: 5000 Valid steps: 1000
Other logging data.
Upon starting the training with onmt_translate, my training accuracy starts off at 7.65 and goes into the low 70s by the time 5000 steps are over. But, in that time frame, my validation accuracy goes from 24 to 19.
I then use bleu to score my test set, which gets a BP of ~0.67.
I noticed that after trying sgd with a learning rate of 1, my validation accuracy kept increasing, but the perplexity started going back up at the end.
I’m wondering if I’m doing anything wrong that would make my validation accuracy go down while my training accuracy goes up? Do I just need to train more? Can anyone recommend anything else to improve this model? I’ve been staring at it for a few days. Anything is appreciated. Thanks.

ANSWER
Answered 2021-May-01 at 18:25my validation accuracy goes down the more I train while my training accuracy goes up.
It sounds like overfitting.
10K sentences is just not a lot. So what you are seeing is expected. You can just stop training when the results on the validation set stop improving.
That same basic dynamic can happen at greater scale too, it'll just take a lot longer.
If your goal is to train your own reasonably good model, I see a few options:
- increase the size to 1M or so
- start with a pretrained model and fine-tune
- both
For 1, there are at least 1M lines of English:Spanish you can get from ModelFront even after filtering out the noisiest.
For 2, I know the team at YerevaNN got winning results at WMT20 starting with a Fairseq model and using about 300K translations. And they were able to do that with fairly limited hardware.
QUESTION
I've been trying to make a custom block in the Blockly workspace that changes the options in drop-down fields based on the selection of a previous drop-down field in the same block. About the block:-
- There are three dropdown fields
- All are populated dynamically using Blockly.Extensions
- All codes are present below
I've implemented an 'onchange' function to the blockly initialization that gets the change data through the 'event' variable and responds accordingly. I'm having problems trying to update the changing drop-down fields. Please assist.
Code
...ANSWER
Answered 2021-Apr-25 at 03:31Thanks to @beka from Google Blockly groups at https://groups.google.com/g/blockly.
The main problem here was conceptual. A block has
- inputs: field rows that can have anything like value blocks (puzzle piece input) or statement blocks (lego input)
- fields: like from HTML. these can be text boxes, drop-downs, images, etc.
Both the input and the field can have names. And it is good practice to name them differently.
As seen in my extensions, I'd taken my input this.getInput('columnInput')
and appended a field .appendField
with the same name. Due to this, the input had a field with the same name.
Here are the corrections:
- to the extensions:
