ValueError: Mime type rendering requires nbformat>=4.2.0 but it is not installed

I was trying to print a plotly plot in Visual Studio Code and caught this error:

---------------------------------------------------------------------------

ValueError: Mime type rendering requires nbformat>=4.2.0 but it is not installed

The code I used:

import plotly.graph_objects as go
from plotly.subplots import make_subplots
import plotly.express as px

df = df[df['Data']>0]
df['Timestamp'] = pd.to_datetime(df['Timestamp'])
df = df[(df['Id'] ==1)|(df['Id'] ==6)]

dfp = pd.pivot_table(df,
                     values='Data',
                     index=['Timestamp'],
                     columns=['Id'],
               )
nrows = len(dfp.columns) 

fig = make_subplots(rows=nrows,
                    cols=1,
                    subplot_titles=['Id '+str(c) for c in dfp.columns])

# add traces
x = 1
for i, col in enumerate(dfp.columns):
    fig.add_trace(go.Scatter(x=dfp.index, y=dfp[col].values,
                             name = 'Id '+str(col),
                             mode = 'lines',
                             ),
                  row=i+1,
                  col=1)

fig.update_layout(height=nrows*500)
fig.show()

I tried pip install nbformat in the console following this feed on GitHub and this question on stackoverflow but it did not work.

However, it seems the code could run with the last 2 rows removed:

fig.update_layout(height=nrows*500)
fig.show()

Method 1

reinstall ipykernel via

pip install ipykernel

Method 2

pip install --upgrade nbformat
