Steps to reproduce the issue

import plotly.express as px
f = px.line(x=[_ for _ in range(10)], y =[2* _ for _ in range(10)])
f.show()

# also
import matplotlib.pyplot as plt
plt.plot([_ for _ in range(100)], [_ for _ in range(100)])
plt.show()

Additional information

The generated plots are rendering on EBrains 24.04 JupyterLab but not on the EBrains release candidate. After adding %matplotlib inline, matplotlib plots were rendered, but no solution for Plotly ones.

import matplotlib.pyplot as plt
%matplotlib inline 
plt.plot([_ for _ in range(100)], [_ for _ in range(100)])
plt.show()

things tried and did not work

import plotly.io as pio pio.renderers.default = 'notebook'
