I've stuck with an issue that I have a slider but It's not interactive, I followed by documentation but even ready solution didn't worked, how to solve that? Not worked in Google Colab and Jupyter Notebook. I have already tried to change matplotlib backend kernel from qt to ktinker but nothing
my code :
%matplotlib inline
!pip install --upgrade matplotlib
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import Slider, Button
# The parametrized function to be plotted
def reliability_graph (t,mu_,lambda_):
return (mu_/(lambda_ mu_)) (lambda_/(lambda_ mu_))*np.exp(-(lambda_ mu_)*t)
t = np.linspace(0, 10,1000)
# Define initial parameters
init_mu = 0
init_lambda = 0.1
# Create the figure and the line that we will manipulate
fig, ax = plt.subplots()
line, = plt.plot(t, reliability_graph (t,init_mu,init_lambda), lw=2)
ax.set_xlabel('Relibility')
# adjust the main plot to make room for the sliders
plt.subplots_adjust(left=0.25, bottom=0.25)
# Make a horizontal slider to control the frequency.
axmu = plt.axes([0.25, 0.1, 0.65, 0.03])
mu_slider = Slider(
ax=axmu,
label='Mu',
valmin=0,
valmax=1,
valinit=init_mu,
)
# Make a vertically oriented slider to control the amplitude
axlambda = plt.axes([0.1, 0.25, 0.0225, 0.63])
lambda_slider = Slider(
ax=axlambda,
label="Lambda",
valmin=0,
valmax=1,
valinit=init_lambda,
orientation="vertical"
)
# The function to be called anytime a slider's value changes
def update(val):
line.set_ydata(reliability_graph(t, mu_slider.val, lambda_slider.val))
fig.canvas.draw_idle()
# register the update function with each slider
mu_slider.on_changed(update)
lambda_slider.on_changed(update)
# Create a `matplotlib.widgets.Button` to reset the sliders to initial values.
resetax = plt.axes([0.8, 0.025, 0.1, 0.04])
button = Button(resetax, 'Reset', hovercolor='0.975')
def reset(event):
mu_slider.reset()
lambda_slider.reset()
button.on_clicked(reset)
plt.show()
My aim is to get a graph with working sliders ,so that I can change values of my parameters interactively. The problem is that sliders aren’t works, they appears as a picture not an interactive object

I've never used sliders or buttons in Colab, but by running your code and introducing the two-point library from the error message, the graph and slider buttons are now enabled. Here is the link to
