Astropy weighted circular mean with numpy ndarrays, encountering TypeError: only integer scalar arrays can be converted to a scalar index

Hello all and thank you for any assistance in advance.

I am using the astropy circmean function (https://docs.astropy.org/en/stable/api/astropy.stats.circmean.html) to evaluate the weighted circular mean of an array of angles. The function takes a numpy ndarray for the angles in radians and another ndarray for the weights. I am getting a type error when trying to input a numpy array for the weights. I can reproduce the error with this code:

import numpy as np

from astropy.stats import circmean

circmean(np.array([.05, -np.pi/2, np.pi]), np.array([1, 1, 10]))

Error:

TypeError: only integer scalar arrays can be converted to a scalar index

I tried checking that the arrays were the required data type and changing the data type of the weights entries. The function works without the weights, but I need to use the weighting. I was expecting the function to work and calculate the desired weighted mean.

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
