figure not rendered in jupyter notebook with default renderer

[rra88]

Running the example code below (from https://plotly.com/python/graph-objects/) in a jupyter notebook, the figure does not render. Overriding the default renderer like so
fig.show(renderer='iframe')
causes the figure to render, but I want to use the default renderer.

df = pd.DataFrame({
  "Fruit": ["Apples", "Oranges", "Bananas", "Apples", "Oranges", "Bananas"],
  "Contestant": ["Alex", "Alex", "Alex", "Jordan", "Jordan", "Jordan"],
  "Number Eaten": [2, 1, 3, 1, 3, 2],
})

import plotly.express as px

fig = px.bar(df, x="Fruit", y="Number Eaten", color="Contestant", barmode="group")
fig.show()

The packages of the environment I used: package_list.txt
