UserWarning: Message serialization failed with: Out of range float values are not JSON compliant

[antonioalegria]

I'm constantly getting this message in stderr when displaying a pandas dataframe. This pollutes what the agent sees and may even impact our ability to getting the displayed dataframe data.

/usr/local/lib/python3.10/site-packages/jupyter_client/session.py:721: UserWarning: Message serialization failed with:
Out of range float values are not JSON compliant
Supporting this message is deprecated in jupyter-client 7, please make sure your message is JSON-compliant
  content = self.pack(content)

This is probably in your serialization code, perhaps? Can you check this and see if you or us can mitigate this warning?

This happens with a e2b sandbox template created today with the latest version of e2b.

Hey, thanks for reporting. Will take a closer look. Do you have an example code I can try where the issue is occurring?

[antonioalegria]

Here you go.

import pandas as pd
import numpy as np

# Data for the DataFrame
# Using a dictionary where keys are column names and values are lists of column data
data = {
    'SpecialFloats': [
        0.0,             # Standard float zero
        np.nan,          # Not a Number (from NumPy)
        pd.NA,           # Pandas' dedicated missing value marker
        None,            # Python's None, often treated as NaN in float columns
        np.inf,          # Positive infinity (from NumPy)
        -np.inf          # Negative infinity (from NumPy)
    ]
}

# Create the Pandas DataFrame
df = pd.DataFrame(data)
display(df)
