dtale.show() error without data about dtale HOT 4 CLOSED

So @FedererKK it actually can be started without loading any data. If you do that it should prompt you with a popup to upload some data using the UI (as shown here)

You have not added any data to the dtale instance, and you can not do that. It is expected behavior

import dtale
import pandas as pd

df = pd.DataFrame([dict(a=1,b=2,c=3)])

# Assigning a reference to a running D-Tale process.
d = dtale.show(df)
