Pi | Processing Ideas is an inspiring space

I am trying to run a simple parallel program on a SLURM cluster (4x raspberry Pi 3) but I have no success. I have been reading about it, but I just cannot get it to work. The problem is as follows:

I have a Python program named remove_duplicates_in_scraped_data.py. This program is executed on a single node (node=1xraspberry pi) and inside the program there is a multiprocessing loop section that looks something like:

I am trying to make a next-word prediction model with LSTM + Mixture Density Network Based on this implementation(https://www.katnoria.com/mdn/).

Input: 300-dimensional word vectors*window size(5) and 21-dimensional array(c) representing topic distribution of the document, used to train hidden initial states.

Output: mixing coefficient*num_gaussians, variance*num_gaussians, mean*num_gaussians*300(vector size)

x.shape, y.shape, c.shape with an experimental 161 obserbations gives me such:

(TensorShape([161, 5, 300]), TensorShape([161, 300]), TensorShape([161, 21]))

I tried to implement next progress bar in my react app.

For now, I am using next code

I know there are a few answer for this, but it seems this one is a bit different. I need to change doughnut chart, rounded the first one and the last but one too. So in my example the black (first dataset) only would be rounded on the beginning (one side) and the gray (last but one) would be rounded at the end, like on the picture.

Of course, this is the latest version (v3) of Chart.js.

I used some code from here: Chart.js Doughnut with rounded edges and text centered

Maybe it's better with a custom chart, but I couldn't even get this far with that.

This is my code so far. Only makes rounded the first dataset and unfortunately both sided of it.

I am using Openocd to debug my code remotely for STM32 via Raspberry pi as detailed in this tutorial: https://learn.adafruit.com/programming-microcontrollers-using-openocd-on-raspberry-pi

Whenever I run openocd it starts gdb server on port 3333 which is default of course as shown in the picture above. My question is that, is there a way to provide a different port number for openocd to start the gdb-debugger on... For example, if I want to run openocd where i want gdb server to start on 3334 instead of 3333 how can i do that.

I intend to do that so that i can run multiple openocd instances for different targets simultaneously connected to a single raspberry pi. Any help will be greatly appreciated. Thanks in advance.

I am working with objects, which have many attributes. I am not using all of the attributes but if I access one then I will use it many times. Is it possible to initialize an attribute only during the first time it gets accessed. I came up with the following code, which is sadly really slow.

I have a raspberry pi 4 running a tomcat server hosting my website. Right now it's blank, and I wanted to do connection tests on it before starting to build it. I am doing this to keep costs minimal and to be able to do other things with it later. However, as you can see in this image, I thought this was the way to set it up, but I get a 522 every time I try to connect to it. (I have IP blurred as it is my home IP). But, when I connect to the IP address directly, even through another wifi network, the page loads. Cloudflare has worked in the past when I was hosting on Google Firebase for a little bit, but once I switched to the pi, it stopped.

Thanks in advance for help.

I've tried for the last few days without too much success to rotate, scale and translate shapes on the canvas. I've read everything I could find on internet about similar issues but still I cannot seem to be able to adapt it to my own problem.

If everything is drawn on the same scale, I can still drag and drop. If I rotate the shapes, then the mouseOver is messed up since the world coordinates don't correspond anymore with the shape coordinates. If I scale, then it's impossible to select any shape. I look at my code and do not understand what I'm doing wrong.

I read some really nice and detailed stackoverflow solutions to similar problems. For example, user @blindman67 made a suggestion of using a setTransform helper and a getMouseLocal helper for getting the coordinates of the mouse relative to the transformed shape.

inverse transform matrix

I spent some time with that and could not fix my issue. Here is an example of what I tried. Any suggestion is appreciated.

I've written a Pi Hardware Interface Server (phis) that uses http protocol to control the hardware connected to my Raspberry Pi (relays, analog measurements, etc). It processes simple requests and responds with plain text. It has been working flawlessly for years and I have written extensive browser-based interfaces to the system. Here's the basic structure:
