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

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings

How to load Javascript with imported modules?

I am trying to import modules from tensorflowjs, and below is my code. test.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title </head> <body> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs@2.0.0/dist/tf.min.js"></script> <script type="module" src="./test.js"></script> </body> </html> test.js import * as tf from "./node_modules/@tensorflow/tfjs"; import {loadGraphModel} from "./node_modules/@tensorflow/tfjs-converter"; const MODEL_URL = './model.json'; const model = await loadGraphModel(MODEL_URL); const cat = document.getElementById('cat'); model.execute(tf.browser.fromPixels(cat)); Besides, I run the server using python -m http.server in my command prompt(Windows 10), and this is the error prompt in the console log of my browser: Failed to loa...
