Python Matplotlib plt.imshow crashes kernel in an unknown way when plotting images

When I run the following code (which runs fine on Google Colab) my kernel crashes

from torchvision import datasets
from torchvision.transforms import ToTensor
import torch.nn as nn
import torch.nn as cnn

train_dataset = datasets.MNIST(
    root = 'datasets',
    train = True,
    transform = ToTensor(), 
    download = True,            
)
test_dataset = datasets.MNIST(
    root = 'datasets', 
    train = False, 
    transform = ToTensor()
)
print(train_dataset)
print(test_dataset)
print(train_dataset.data.size())
print(test_dataset.data.size())

import matplotlib.pyplot as plot
plot.figure(1)
plot.imshow(train_dataset.data[0], cmap='gray')
plot.title('%i' % train_dataset.targets[0])
plot.show()

The very undescriptive error message i get is the following: enter image description here

(This is the click here link shown in the screenshot-image above)

However if I run the following code a one or more cells above the previous code works without crashing the kernel. What is really difficult to understand is even with importing matplotlib with different names doesn't effect this issue...

import matplotlib.pyplot as plt
plt.imshow([[1, 0], [0, 1]]) #this fixes the kernel from crashing if placed before previous code for some strange reason

I know some people (as seen here https://github.com/jupyter/notebook/issues/6219) suggest going back a version or two for different packages. This did not work for me. Since this code runs on colab it means there is some issue with my PC.

I have reinstalled Anaconda and all my python stuff and still am unsuccessful with solving this issue.

Currently my package versions are: Torch Version: 2.0.1+cu117 TorchVision Version: 0.15.2+cu117 Matplotlib Version: 3.5.0

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".
