Datahub python interpreter has problems displaying Pandas dataframes

[jdmarshl]

Bug description

My students I and encountered this problem starting last week. When you call a dataframe, either by name or using df.head(), there is an error message that indicates an indexing problem. Does not happen locally. I am attaching a pdf that shows the output. It seems to do it whenever we call a df object.

Environment & setup

• Hub: Datahub
• Language: Python

How to reproduce

create a Pandas dataframe
call the dataframe, either by itself or using .head()
interpreter displays error message saying that it has an indexing problem across the columns

[jdmarshl]

even did it for the following code block which is there as a kind of toy example

birds = pd.DataFrame({'color':['white', 'grey', 'white'],
'quacks':['yes', 'yes', 'no'],
'type':['duck', 'duck', 'goose']})
birds

Further note--I restarted the kernel, and dataframes displayed as expected. The problem seems to occur when the students or I have been working for awhile in a notebook and then try to display a dataframe. I cannot explain the difference in behavior when I restart the kernel. I will tell students to do that for now.

hey @jdmarshl ! i tried to replicate this earlier today, but was unable to. if this happens again, could you let us know here immediately.

yeah, this is really strange and i'm at a loss to explain it.

I will be careful to see what the state of my (or someone else's) notebook is when the problem occurs. It does not happen when I start the kernel and run a notebook all the way through. I will check on what's happening when students are doing the their labs and let you know when I learn more. jdm Jon Marshall, Ph.D. (he/him) Assistant Dean JSP/Legal Studies
