The :func:`~luigi.task.Task.requires` method is used to specify dependencies on other Task object,
which might even be of the same class.

One nice thing about Luigi is that it's super easy to depend on tasks defined in other repos.
It's also trivial to have "forks" in the execution path,
where the output of one task may become the input of many other tasks.

QUESTION
I have a parent component which contains data to build the rows of a table. A child component renders the actual table. Every row should be deletable, so I created a function inside the parent component to update its state and I passed it to the child component, so it could be called on the click of a button.
Even though the setter function is fired the state is not actually changed. The table is not re-rendered and the useEffect which has files as a dependency is not fired.
I'm not understanding why this happens, here's the problem reproduced in codesandbox. I would be very glad if anyone could help solving this.
Edit: I'm adding the code here since links can break over time, as @UmerAbbas pointed out.
...ANSWER
Answered 2022-Jan-24 at 14:37You need to use the function version of set state.
QUESTION
I have a test pipeline on concourse with one job that runs a set of luigi tasks. My problem is: failures in the luigi tasks do not rise up to the concourse job. In other words, if a luigi task fails, concourse will not register that failure and states that the concourse job completed successfully. I will first post the code I am running, then the solutions I have tried.
luigi-tasks.py
...ANSWER
Answered 2022-Jan-11 at 00:23My suspicion is that luigi doesn't see your config file with return codes. Its default behavior is to return 0, whether tasks fail or succeed.
This experiment should help to debug that:
- Force a failed job: add an
exit 1at the end ofbegin.sh - Hijack the job:
fly -t i -j /-> selectrun-script cd ./run-git; /bin/bash begin.sh- Ensure the luigi config is present and named appropriately, e.g.
luigi.cfg - Re-run the command:
LUIGI_CONFIG_PATH=luigi.cfg bash ./begin.sh - Check output:
echo $?

the IP range written in this way:
10.27.0.0/16
means that the address

is included?
Thanks a lot.

Answered 2022-Jan-04 at 10:00Yeah, 10.27.24.152 is included in your IP range (between your host min and your host max), you can use tools like this one to check by yourself : http://jodies.de/ipcalc?host=10.27.0.0&mask1=16&mask2=

QUESTION
I have an index with 1 million phrases and I want to search in the index with some query phrases in italian (and that is not the problem). The problem is in the order in which the matches are retrieved: I want to have first the exact matches so I changed the default similarity to "boolean" and I thought it was a good idea but sometimes it does not work. For example: searching in my index for phrases containing the words "film cortometraggio" the first matches are:
- Distribuito dalla General Film Company, il film- un cortometraggio in due bobine
- Distribuito dalla General Film Company, il film - un cortometraggio di 150 metri - uscì nelle sale cinematografiche
But there are some better phrases that should be returned before those ones like:
- Robinet aviatore Robinet aviatore è un film cortometraggio del 1911 diretto da Luigi Maggi;
This last phrase should be returned first in my opinion because there is no space between the two words I am searching for.
Using the BM25 algorithm the first match that I get is "Pappi Corsicato Ha diretto film, cortometraggi, documentari e videoclip.". In this case also should be provided the phrase "Robinet aviatore Robinet aviatore è un film cortometraggio del 1911 diretto da Luigi Maggi;" because is an exact match and I don't get why the algorithm gives the other phrase a higher score.
I am using the Java Rest high level client and the search query that I'm doing are simple match Phrase query, like this: searchSourceBuilder.query(QueryBuilders.matchPhraseQuery(field, text).slop(5)
This is the structure of the documents in my index:
...ANSWER
Answered 2021-Nov-03 at 01:20I have replicated your problem in my ambient, same version, same analyzers but I still received the same results. Probably that is for the BM25 algorithm, the other millions of docs influence the score.
I have some suggestions that could help you to solve the problem:
- Don't use the full steaming Analyzers because they are too intrusive, use the light version
- You could complement the light analyzer using the ngram tokenizer
- You could create a bool query that matches first to the fields without the analyzer using a multifield

QUESTION
I have a couple of methods here that are taking longer than I would like to. I'm currently hitting a wall since I don't see any obvious way to write these methods in a more efficient way.
For background, what the code is doing is processing a sales dataset, in order to find previous sales orders related to the same client. However, as you will see, there's a lot of business logic in the middle which is probably slowing things down.
I was thinking about refactoring this into a PySpark job but before I do so, I would like to know if that's even the best way to get this done.
I will highly appreciate any suggestions here.
More context:
Each loop is taking about 10 minutes to complete. There are about 24k rows in search_keys. These methods are part of a Luigi task.
ANSWER
Answered 2021-Nov-03 at 08:47"In very simple words Pandas run operations on a single machine whereas PySpark runs on multiple machines. If you are working on a Machine Learning application where you are dealing with larger datasets, PySpark is a best fit which could processes operations many times(100x) faster than Pandas."
from https://sparkbyexamples.com/pyspark/pandas-vs-pyspark-dataframe-with-examples/
You should also think of a Windows function approach to get the previous order. That will avoid a loop on all records.

...ANSWER
Answered 2021-Oct-27 at 21:37You have one layer of nesting too many. Your first description corresponds to a dictionary whose keys are words, and whose values are dictionaries of (filename, position_list) pairs (e.g. dictionary['mario'] = {'file1.txt': [0], 'file2.txt': [1, 5]} ) rather than a dictionary whose keys are words, and whose values are a list of dictionaries with one filename per dictionary, as you had.

Install luigi
You can use luigi like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
