Исключение, возникающее в режиме отладки PyCharm, но не в режиме выполнения (seaborn, matplotlib) ⇐ Python

[Anonymous]

Я использую

• PyCharm 2021.2.3 Community Edition
• Интерпретатор Python 3.10.0
• matplotlib 3.5.0
• seaborn 0.11.2
• numpy 1.21.4
• pandas 1.3.4
• PySimpleGUI 4.55.1

Когда я запускаю следующий скрипт, в режиме выполнения он работает нормально, но в режиме отладки выдается исключение. Вот сценарий:

Код: Выделить всё

import numpy as np
import pandas as pd
import PySimpleGUI as sg
import seaborn as sns

from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
from matplotlib.figure import Figure

def init_data():
r1 = np.random.rand(5, 4)
columns = [f"var{i}" for i in range(1, 5)]
df = pd.DataFrame(r1, columns=columns)
df.insert(0, 'year', range(2021, 2026))
df.insert(1, 'scenario', 'test1')
ldf = pd.melt(df, id_vars=['year', 'scenario'], value_vars=columns, var_name='percentile', value_name='carbon')
return ldf

def draw_figure(canvas, figure):
figure_canvas_agg = FigureCanvasTkAgg(figure, canvas)
figure_canvas_agg.draw()
figure_canvas_agg.get_tk_widget().pack(side='top', fill='both', expand=1)
return figure_canvas_agg

# define the window layout
layout = [[sg.Text('Plot test')],
[sg.Canvas(key='-CANVAS-')],
[sg.Button('Ok')]]

# create the form and show it without the plot
window = sg.Window('Testing seaborn in PySimpleGUI', layout, finalize=True,
element_justification='center', font='Helvetica 18')

figure = Figure()
ax = figure.subplots()
sns.lineplot(x='year', y='carbon', hue='percentile', data=init_data(), ax=ax)

# add the plot to the window
fig_canvas_agg = draw_figure(window['-CANVAS-'].TKCanvas, figure)

event, values = window.read()

window.close()

А вот трассировка стека:

Кто-нибудь видел это раньше или есть какие-нибудь идеи?
