Cool, thanks for that. FYI I've added a comment here in the Pandas repo, not sure if it's on their radar. One fix might be to be to convert all periods to date time, but you'd need to handle the case of a multi-index where only one of the indexes is Period (my use case and a common-ish format in hierarchical time series analysis). With very little testing, this seems to work... import pandas as pd
df = pd.DataFrame(
dict(
A=[1, 2, 12],
B=[1, 2, 12],
C=[1, 2, 12],
Date1=pd.period_range("2000-01-01", periods=3, freq="A"),
Date2=pd.period_range("2000-01-01", periods=3),
Date3=pd.date_range("2000-01-01", periods=3),
)
).set_index(["A", "Date1"])
def periods_to_timestamps(df):
new_df = df.copy()
for col_name, col in df.items():
if pd.api.types.is_period_dtype(col):
new_df[col_name] = col.dt.to_timestamp()
for level in range(df.index.nlevels):
index = df.index.get_level_values(level)
if pd.api.types.is_period_dtype(index):
new_df.index = new_df.index.set_levels(index.to_timestamp(), level=level)
return new_df
df2 = periods_to_timestamps(df) |

Environment data
I'm using Pandas
2.0.3. This happens in a WSL setup as well as just running in Windows.I didn't explicitly install Jupyter or IPython, I just let VS Code do whatever it had to do (install i-something-kernel to run the interactive window).
Expected behaviour
I should be able to view a DataFrame with the
Periodtype in it (column or index).Actual behaviour
The data viewer crashes
Steps to reproduce:
venvenvironment, installpandas.test.pywith the contents:In VS Code, do
Run Current File in Interactive Window. Confirm the dataframe shows just fine in the interactive window:Click
Variablesin the interactive window, and try to view thedfvariable in the data viewer. Then it crashes.I found this issue #10446 but it was closed as a Pandas issue.
Logs
These logs are when testing with WSL, they're much the same with plain Windows.
