QUESTION
I am following this tutorial: https://towardsdatascience.com/kafka-docker-python-408baf0e1088 in order to run a producer-consumer example using Kafka, Docker and Python. My problem is that my terminal prints the iterations of the producer, while it does not print the iterations of consumer. I am running this example in local, so:
- in one terminal tab I have done:
docker-compose -f docker-compose-expose.yml up
where my docker-compose-expose.yml is this:
ANSWER
Answered 2022-Mar-26 at 12:23Basically I had understood that the problem was in some images/processes that were in execution. With docker-compose stop
and docker-compose rm -f
I solved.
QUESTION
How can I pass tuple with only one element as param in sql query Python?
I have tried this solution suggested here: imploding a list for use in a python MySQLDB IN clause
...ANSWER
Answered 2022-Mar-25 at 20:33I don't think what you are trying to do is possible in the Python3 version of the MySQL Connector. The code converts Python dict values into SQL syntax, depending on the Python type. But in the connector code, only scalar types are supported, no list or tuple. See https://github.com/mysql/mysql-connector-python/blob/master/lib/mysql/connector/conversion.py#L221-L372
I'd use the solution in the accepted answer to imploding a list for use in a python MySQLDB IN clause, which is to generate N placeholders for the number of items in your list, plus one more placeholder for the value to compare to created_at
. Then merge the list with the date value and pass that.
QUESTION
A base docker image I am working with is a relic using python 2.6.6 ..
So how can I install pip on this system - given the long obsolescence of the python version and the lack of availability of tools even to upgrade to newer versions.
Update I had already gone through all of the options in the other question How to install pip for python 2.6?.
- get-pip link is 404 https://bootstrap.pypa.io/2.6/get-pip.py
yum install python-pip
does not work sincepip
postdates2.6
In general 2.6 is so out of date there are no easy answers to be found. I am looking for someone who has an approach even with the long period since this version was obsoleted.
...ANSWER
Answered 2022-Mar-23 at 15:49The structure of the site was changed. Pip is now under subdirectory pip
. Pip for Python 2.6 is at https://bootstrap.pypa.io/pip/2.6/get-pip.py

I have installed open source qt creator (free version) and creating very simple desktop application. I am able to create simple window but when I am running I am getting following error:
I have tried to follow this page but could not understand to fix this issue
...ANSWER
Answered 2021-Jul-31 at 19:55You're seeing an informative message from a new and experimental feature in PySide6 called "Custom Widgets". To silence the message you can set the variable "PYSIDE_DESIGNER_PLUGINS" to "." for the current folder.
https://www.qt.io/blog/qt-for-python-6.1 states:
A new experimental plugin for Linux and Windows is shipped that provides > support for writing custom widgets in Python, which can then be selected > from Qt Designer to be used in layouts. Some extra magic is required to > enable this on macOS. We hope to have it ready in 6.1.1!

...ANSWER
Answered 2021-Nov-25 at 12:44This isn't supported in SKLearnProcessor. You'd need to package your dependencies in docker image and create a custom Processor
(e.g. a ScriptProcessor with the image_uri of the docker image you created.)
QUESTION
I have just seen that support for AAB files have just been introduced in Python for Android (p4a). Considering that, fom August 2021, new apps are required to publish with the Android App Bundle on Google Play, this is a crucial addition for any Python dev working on Android apps.
Since I'm currently using Buildozer via Docker, I'd like to know which are the steps to make it generating an .aab instead of (or along to) the traditional .apk
For the sake of clarity, here is what I use to run Buildozer from inside a container (using Docker for Windows) to make the .apk file:
...ANSWER
Answered 2021-Nov-26 at 13:34The community has finally completed the AAB support for Buildozer. Although it is still a pending pull request, it is already possible to create the AAB, and I have figured out how to do it using Docker.
I have found two very interesting gists that helped me a lot (this one about creating an AAB with Buildozer on Ubuntu, and another one about signing an AAB on the same platform). However, I have run everything on Windows via Docker, so I think it is a good idea to share how I did it.
Clone the feat/aab-support branch of the Buildozer repository in your local machine:
QUESTION
I'm using this workflow to debug a generic Python application inside a Docker container with vscode.
If i introduce an error to my main.py, such as importing a package that doesn't exist, and press F5 to debug in VSCode, after building the docker image, it fails silently and doesn't provide any useful error message.
e.g:
Executing task: docker-run: debug < docker run -dt -P --name "projectname-dev" --label "com.microsoft.created-by=visual-studio-code" -v "c:\Users\tim.vscode\extensions\ms-python.python-2021.10.1317843341\pythonFiles\lib\python\debugpy:/debugpy:ro" --entrypoint "python3" "projectname:latest" < add88efdff111ae904a38f3d52a52d8191a95f1d53c931a032326ed2958218b3
Terminal will be reused by tasks, press any key to close it.
If i remove the error, I have working code, and by running it manually
docker run projectname
I can see the code works.
However it still fails to debug in vscode, failing silently. A breakpoint set on the first line is never reached. There is no message produced at all from vscode.
How can I see the error message in this case?
