Problem Description

‘FutureWarning’ generated in error - appears to be a bug. Fresh install of Spyder Python 3.6.5 via Anaconda, just two lines of code in a new console (below) begin to trigger error - after a multi-hour work session. Thank you!

What steps reproduce the problem?

1. import pandas as pd
2. nov17_3mo = pd.date_range(end=‘2017-11-01’, periods=3, freq=‘MS’)

What is the expected output? What do you see instead?

Object is created as requested - but I get additional error: C:\Users\pjacob\AppData\Local\Continuum\anaconda3\lib\site-packages\spyder\widgets\variableexplorer\utils.py:414: FutureWarning: ‘summary’ is deprecated and will be removed in a future version. display = value.summary()

Once it starts, this error comes up after every line of code executed in the console, e.g., print(1+1)

@dalthviz, please help me to solve this one. Here

https://travis-ci.org/spyder-ide/spyder/jobs/395955090#L1512

you can find here all warnings generated by the latest Pandas.

For each one please do the following:

try:
    display = value._summary()
except AttributeError:
    display = value.summary()

This is for summary, but you get the idea for the rest of them: the new method name must be called first and the old one second. This way we will guarantee compatibility with old Pandas versions and avoid these warnings.

Yes clearly this needs to be fixed.

If you want you can test a possible workaround, try changing:

C:\Users\pjacob\AppData\Local\Continuum\anaconda3\lib\site-packages\spyder\widgets\variableexplorer\utils.py line 414

from

display = value.summary()

to

display = value._summary()

and see if that fixes the problem. Then we will have a possible solution.
