Magnetic | SpriteKit Floating Bubble Picker 🧲 | iOS library

I have a 3d image (32, 32, 32)in grayscale (is an image taken from a magnetic resonance image) and I'm trying to build a simple Autoencoder with it. The problem i'm getting is when I try to fit the model to the image (model.fit()) because I'm getting this error:

ValueError: Input 0 of layer sequential is incompatible with the layer: : expected min_ndim=5, found ndim=4. Full shape received: (32, 32, 32, 1)

This is a .nii image. Taken from other posts that ask the same question for conv2d I tried to adapt some answers and I did reshape but I don't know why it's still expecting ndim=5, shouldn't be the ndim 5 the batch dimension that keras add internally??

This is what I did:

Here is what I'm trying to do: In games, when approaching an NPC, players will be given an indicator to interact with the NPC. The indicator shows up when the player is within a certain distance of the npc. It also goes away when the player moves away from the NPC.

Here is what I tried: I had thought that it would be as easy as using the physics world methods of didBegin/didEnd contact and a transparent cylinder around the NPC as a contact trigger. This unfortunately didn't work because didBegin/didEnd methods are called every frame and not when contact is made (this is how I thought it worked).

I also tried to use PHYKit from GitHub but It didn't seem compatible to what I was trying to do.

I've thought about giving the NPC a Magnetic field and checking if player is within the scope of that field but it doesn't look like there is way to check for that (maybe I missed something).

I thought I could also use hitTestWithSegment but didn't understand how I can apply it to what I'm trying to do.

There also doesn't seem to be anything online to help with this (I've checked for the last three days so if there is anything I'm willing to see what it's about).

The Question: How can I check if a node is within a certain distance of another node and when it left that area?

I want to constrain the spin of the bulk atoms while letting the free surface atoms of my supercell relax their magnetic moment. Is it possible in PyIron+SPhinx to constrain the spin of a subset of atoms (not all of them) in the supercell?

Seems very basic but I can't find any info on why is it happening.

I'm using the canonical MDN example to sort an array of objects and it seems the order in which the elements are passed into the compare callback is the opposite order. e.g.

this is my website that I am developing, and I trying to develop a calculator which depending on the subject and equation your are trying to use, the calculator will give you an answer.

I made two dropdown menus, however, when I hover over the "Physics" menu, for some reason the "Maths" menu is covered. Also, the list for "Physics" is a bit too long and I wanted to make a scroll bar, but I don't know how to.

I tried to look on w3schools and other resources, but I couldn't find a solutions which solved my problem.

I have downloaded the HTML for a webpage using python-requests. I now need to extract a JSON object from this content. I have located the JSON object with some BS4 methods. However, I don't know how to extract it from the BS4 object. Here is my code

I am building a C# application that handles a custom protocol used in my web application.

The links are like:

I have a section of code that I am using to calculate magnetic fields and magnetic vector potentials. I do various things to calculate an inverse curl, but I'm getting stuck on a namespace issue in python and I'm not sure how to move forward.

The code (shortened a little) works like this

I have following dictionary in python:
