Ipykernel working tool slow and not show result in Jupyter Notebook

[chuongmep]

I have this problem when I upgrade vs code to new version

• VS Code Version: 1.62.2
• OS Version: Windows 10 20H2

Steps to Reproduce:

1.Try with some code

from mtcnn import MTCNN
import cv2
from skimage import io
import matplotlib.pyplot as plt
img = io.imread("people.jpg")
plt.imshow(img)
# detect faces in the image
results = detector.detect_faces(img)
results
detector = MTCNN()
# show results
for i in range(len(results)):
    x1, y1, width, height = results[i]['box']
    x2, y2 = x1 + width, y1 + height
    cv2.rectangle(img, (x1, y1), (x2, y2), (0, 255, 0), 2)
# show the image
plt.imshow(img)

2. It runs too slow in show result and show something

Thanks for the bug. It sounds like the kernel crashed.

Can you include the contents of the 'Jupyter' output panel?

Sure, you can check error.txt LogRunAll.txt Package Version

I want to inform you about this, I have removed Cuda 11.5, CudaDNN and reinstalled 11.4, also I reinstalled python IDE, they work for me now.

Thanks for the information. Your kernel definitely died (can see it in the output here:)

{"jsonrpc": "2.0", "method": "log", "params": {"level": "WARNING", "msg": "Kernel has exited with exit code 3221226505, ", "pid": 11876}}
Warn 2021-11-17 09:52:57: Python Daemon (pid: 11876): Kernel has exited with exit code 3221226505,

Glad that it's working now.
