I got the following error while running Jupyter notebook:

No such comm: b008b53680824e6baec529d8c991f5c4

The code in the cell is:

df['ID'].unique()
df_1 = df.loc[df['ID']==10].copy()
df_2 = df.loc[df['ID']==20].copy()

It throws the error once and by running the cell again it will work. What is the problem here? And why by second run it does not throws?
