Subclassing Numpy Array - Propagate Attributes

I would like to know how custom attributes of numpy arrays can be propagated, even when the array passes through functions like np.fromfunction. For example, my class ExampleTensor defines an attribute attr that is set to 1 on default. import numpy as np class ExampleTensor(np.ndarray):     def __new__(cls, input_array):         return np.asarray(input_array).view(cls)     def __array_finalize__(self, obj) -> None:         if obj is None: return         # This attribute should be maintained!         self.attr = getattr(obj, 'attr', 1) Slicing and basic operations between ExampleTensor instances will maintain the attributes, but using other numpy functions will not (probably because they create regular numpy arrays instead of ExampleTensors). My question: Is there a solution that persists the custom attributes when a regular numpy array is constructed out of subclassed nump...

I have a .enc file from an Android Game/App, how do i extract/open it?

So basically, I found a game/app on the Play Store that uses a dynamic image(or some sort of GIF) when you view a character in the game. I want to be able to use that dynamic image in one of my projects(non-commercial, personal). So i went through the trouble of scanning all of the game files from the folders just to find it as a ".enc" file. How do I get the image from the .enc file? -Also posted on SuperUser, but I think i might get better answers here

how to compare the runtime input with text file

I want to compare the input and text file word. The text file has: one two three Run time input assigned to a variable var: read -p " enter the value : " var while read first do   a=$first   if [ "$a" == "$var" ]   then     echo  " $var is found "   else     echo " $var is not found "     read -p " please enter correct value " $var   fi done < word.txt I tried above code in my script, but it is not working.

Plausible reason why my time machine can only go to certain points in time?

So, I have built a Time-Traveling machine. It’s a prototype, and I’ve noticed a few kinks in the machine. If the control pad gets jammed in home mode, the universe will repeat the same day for all eternity. Also, I noticed that my machine can only go back in time within a limited range. I can go anywhere in time between August 12th, 1941 and the present. This is very important to the plot of my story, and I want to give a logical reason why it is that way. My question is, what is a plausible reason why my time machine is limited like this?

What is considered 'insulting a Muslim'? And is it a sin? If so, is it a minor or major scene?

Assalamu 'Alaikum, My question is kinda lengthy here. So, the important question is regarding a situation. So, there was this guy who bought a wrong book, since it had the same name but the book had a different number on it. Everybody was laughing, not as insult though, just because the situation was funny when he realised he was doing the wrong sums from the wrong book. So, when everybody was commenting on it, someone said, obviously as a joke, "can't you read numbers?" and laughed it off. The guy who bought the wrong book obviously didn't mind and now, he probably doesn't even remember about that remark since everybody was talking. Now, it is not even a valid insult because it has nothing to do with him not being able to read numbers. He didn't specify the book number and that's how he got the wrong book. The insult is kinda like jokingly calling Albert Einstein stupid because he forgot his pen or something. And the person who "insulted...
