Pycode segmentation fault when running from Docker container using XLaunch/XMing

i'd like to play around with pygame but i'd like to use a docker container to do so, but i can't render the pygame window on my host.

I'm working on Windows 10 as host system and I've created a docker container with the image ''python'' (Debian 11);

root@docker-desktop:/home# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

I installed XMing/XLaunch on the host;

I was able to connect the XLaunch/XMing window to the Docker container by setting the env variable DISPLAY=host.docker.internal:0.0 (i can run xcalc just fine, and python applications using tkinter)

from tkinter import *
window=Tk()
# add widgets here

window.title('Hello Python')
window.geometry("300x200+10+20")
window.mainloop()

the previous code works just fine, but when i try to run a python application using the pygame library, like this:

import pygame
pygame.init()
pygame.display.set_mode((200,200))

it gives me this error

root@docker-desktop:/home# python test.py
pygame 2.1.2 (SDL 2.0.16, Python 3.10.2)
Hello from the pygame community. https://www.pygame.org/contribute.html

i tried some pygame examples from the pygame documentation with the same result, how can i avoid this segmentation fault? or is there another way to have a gui without the use of XLaunch/XMing?

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...
