QUESTION
I have tried to catch the idea of “Module not found” when importing a Python package within a plpython3u procedure, I did not know how to use the accepted answer there to make it run on Linux. Normally, this here should be a duplicate, but if there is a difference with with MacOS in the used paths, it might be good for a new question.
Installation of PostgreSQL 13I am on WSL2 (Ubuntu 20.04). I installed with the commands of the official PostgreSQL Downloads page from the PostgreSQL Apt Repository for Ubuntu.
...ANSWER
Answered 2021-Sep-01 at 18:24The issue is that this:
python3.8 -m pip install pandas
installs a package(pandas in this case) to the site-packages
in the home directory of the user running the command, so:
/home/my_user/.local/lib/python3.8/site-packages
The plpython3u
extension running in Postgres is looking for the package in the system wide site-packages
. To get the package there you need to do:
sudo python3.8 -m pip install pandas

is a numpy array, you cannot index an array with a string. You need to convert it first to a dataframe with this:

Trying to find the coordinates of K-means cluster centers on groups in a large data frame. One option is to brute-force loop through. But it'd be nice to figure out some tidy way of making it work. This previous Q&A wasn't clear. Any ideas? Here are some things I've tried, and a MCVE I made via reprex
. Many thanks,

QUESTION
I am attempting to create a Dockerized Flexdashboard app. I am able to run it locally, but not in the localhost. I can, however, run shiny apps just fine within the same docker image. Interestingly, the error message in the localhost says 'Not Found' for the Flexdashboard app which is different than when a page doesn't exist at all ('Page Not Found').
How can I Dockerize a Flexdashboard app?
MWE ...ANSWER
Answered 2020-Mar-18 at 13:27This is likely a result of a bug in the rmarkdown package being used in your image (rmoarkdown v. 1.18) and is related to this: https://github.com/rstudio/rmarkdown/issues/1731 and https://github.com/rstudio/rmarkdown/issues/1714. I'm guessing http://localhost:3838/kmeansflex/kmeans2.Rmd does indeed work.
Here's how you could test this. Make a shiny app in the apps folder to see what version of rmarkdown is being run. Make a folder in apps called 'rmarkdown'. Then put the following simple ui.R and server.R scripts in there to build a shiny app (we know shiny apps render for you) to determine what version of rmarkdown you have:

Install KMeans-Clustering
You can use KMeans-Clustering 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.
