Jupyter notebook crashes, does not show variables and restarting does not fix #16843

Description

@Georgewxm

Type: Performance Issue

I ran the code below and got the following error message:

The window is not responding
You can reopen or close the window or keep waiting.

also after that message no matter which cell I run, what I run the results dont show up, not even when the cell triggers errors -it's barely usable

also I tried re-opening the notebook, turning on and off extensions, switching to vscode (not insider), everything! nothing would help.

plz help thank u

code:

import pandas as pd
import numpy as np

px = pd.read_csv("cta_data/px.csv", parse_dates=["date"], index_col="date")
rx = pd.read_csv("cta_data/rx.csv", parse_dates=["date"], index_col="date")
vx = (rx.ewm(span=5, min_periods=5).std() + rx.ewm(span=21, min_periods=21).std() + rx.ewm(span=63, min_periods=63).std()) / 3

cutoffs = [5, 10, 21, 63, 126, 252]
mas = {}
mas_zscores = {}
z_window_multiplier = 2

for col in px.columns:
    # Do frequency de
    ma = {}
    for c in range(len(cutoffs)):
        if c == 0:
            ma[f"real - ma{cutoffs[c]}"] = px[col] - px.ewm(span=cutoffs[c], min_periods=cutoffs[c]).mean()[col]
        else:
            ma[f"ma{cutoffs[c-1]} - ma{cutoffs[c]}"] = (
                px.ewm(span=cutoffs[c - 1], min_periods=cutoffs[c - 1]).mean()[col] - px.ewm(span=cutoffs[c], min_periods=cutoffs[c]).mean()[col]
            )
    ma[f"ma{cutoffs[c]}"] = px.ewm(span=cutoffs[c], min_periods=cutoffs[c]).mean()[col]
    ma = pd.DataFrame(ma)
    mas[col] = ma

    ma_z = pd.DataFrame(columns=ma.columns, index=ma.index)

    for c, cutoff in enumerate(cutoffs):
        z_window = cutoff * z_window_multiplier
        ma_z.iloc[:, c] = (ma.iloc[:, c] - ma.iloc[:, c].ewm(span=21, min_periods=21).mean()) / ma.iloc[:, c].ewm(
            span=21, min_periods=21
        ).std()

    mas_zscores[col] = ma_z


ma.diff().corr().style.background_gradient()

ma_z.diff().corr().style.background_gradient()

list(mas.keys())

Might be dupe of microsoft/vscode#251731

On Ubuntu 22.04, downgraded to 1.100 and disabled automatic updates to solve the problem. I had to uninstall, restart code, then install some packages again after the downgrade. For me the exact commands were:

$ sudo apt install code=1.100.3-1748872405
$ sudo apt-mark hold code

Thank you for filing this issue and sorry you are running into this.

Are you running into this issue when you run some simple code like print("Hello World")
