            Nuxt application local development server constantly reloading
            Asked 2022-Apr-03 at 10:40

            I have a Nuxt ^2.15.8 application which is constantly reloading after I run yarn dev.

            The console will show a message like ↻ Updated 1647868577626, and then the application is rebuilt, as if I just run yarn dev. This happens constantly over and over, without me doing any changes in the code.

            I googled a bit, and found applications like gitkraken might be modifying the content of the .git folder and that could trigger a reload.

            So I keep gitkraken closed.

            I also added these lines to my nuxt.config.js file:

            Tika server fails to start in airflow(from the fourth simultaneous run) deployed on kubernetes
            Asked 2022-Mar-14 at 13:57

            I wanted to ask if any of you have encountered a similar error.

            I am working in a company where we are using airflow, deployed on Azure kubernetes.

            We have a Dag in charge of extracting some information about different documents. Among many of the things we extract from the documents, we use tika to extract the xml.

            The flow would be:

            • We upload 10 documents.
            • 10 different DAGs are created to extract the information from the documents.
            • When it gets to the point of using tika to extract the xml some DAGS start to fail because the tika server is not able to initialise itself.

            Some facts about the task using tika-server:

            • We have set the retries to 3
            • We have limited the simultaneous execution of this task to 3, so it never fails.

            Accessing module in parent folder
            Asked 2022-Feb-14 at 22:00

            I was trying to implement something that I saw in a tutorial on Real Python. In the tutorial there a testing module (or do you call that a test file?) is in a directory test/ and the code is in a directory rptodo/, and the test file imports the object to be tested with from rptodo import __app_name__, __version__, cli. This does not run by itself; an error ModuleNotFoundError: No module named 'rptodo' occurs. But this does allow pytest to run the code. I then tried redoing this with my own example code and I get the same error even in pytest. What did I do wrong in creating the module?

            ANSWER

            Answered 2022-Feb-14 at 22:00

            I found the answer looking in one of stackoverflow's similar questions, but this is so un-intuitive that I feel the need to post the answer here.

            The folder with the test has to be made into a package by creating a file __init__.py. Pytest then knows to look at the parent folder for the module package that the required object is in.

            Ironically, the folder being referenced does not need an __init__.py file to be found as a module for importing. Only the current folder making the call needs to be a module with __init__.py .

            Not only when importing a module from a different folder, but even when accessing a module from the current folder, pytest needs the folder to have a __init__.py file to be able to import the files with the code for testing.

            How can I get a --version to the root of a typer.Typer application?
            Asked 2022-Feb-06 at 14:24

            My CLI applications typically have subcommands. I want to have the --version flag at the root of my CLI applications, but with Typer I've only seen ways to put it to a command. I want to add it to the typer.Typer object (the root) itself. How can I do that?

            What I've tried ...

            ANSWER

            Answered 2022-Feb-06 at 14:24

            This is addressed in the documentation:

            But as those CLI parameters are handled by each of those commands, they don't allow us to create CLI parameters for the main CLI application itself.

            But we can use @app.callback() for that.

            It's very similar to @app.command(), but it declares the CLI parameters for the main CLI application (before the commands):

            Based on the line your error is occurring on, it looks like you have a malformed feature list somewhere. A feature list looks like alpha=yes|beta=no. It seems like you might have something that looks like alpha=yes|beta, which is invalid.

            I think the underscore by itself is a special case and should be valid, but maybe you have some other kind of filler?

            You can debug this by modifying the conllu_sentence_to_doc function in conllu_to_docs.py to print the morphs value before calling doc = Doc(...).
