Cannot preview data in VScode

Scolymus commented 8 months ago

Environment data

VS Code version: 1.87.0, attached-container, desktop
Jupyter Extension version (available under the Extensions sidebar): 2024.2.2024022602
Python Extension version (available under the Extensions sidebar): 2024.2.1
OS (Windows | Mac | Linux distro) and version: Ubuntu docker
Python and/or Anaconda version: python:3.11 docker.
Type of virtual environment used (N/A | venv | virtualenv | conda | ...): N/A
Jupyter server running: Local | Remote | N/A. I'm using the extension from VS.code

Expected behaviour

I have a class that derives a DataFrame (yeah, weird thing...). This object is not recognized by Jupyter to preview, and therefore we added a method called "as_df", which basically does:

            return pd.DataFrame(self)

Then by using this the jupyter extension was able to show the df in vs.code.

Actual behaviour

I never restart, but the other day I had to restart vs.code and now I'm getting:

Traceback (most recent call last): File "<string>", line 1, in <module> NameError: name 'as_df' is not defined. View Jupyter [log](command:jupyter.viewOutput) for further details.

I guess it updated something. I haven't tried going to a previous release of vs.code, but I tried with jupyter extension, and no luck. Also I tried to update the pandas version within the docker (I'm vieweing it from inside dev containers) and no luck neither.

Note: Sometimes I even get a message (different, attaching it in the log section) for simple df.

May it be related with ticket?

Steps to reproduce:

Create a breakpoint, and see the df variable.

what action are you taking when you see that error? It sounds like your as_df method isn't being added correctly (did the imported file change?), but I'm not sure why the extension's code is trying to call it.

Is that second log showing that a standard dataframe object is also failing in some way?

Scolymus commented 8 months ago

No, the imported file haven't changed. I never restart the laptop, and I had to do it for some updates, so I guess a new VS.code / jupyter version was updated.

To see this error I put a breakpoint and try to see the variable data. In the variables section, under "RUN AND DEBUG" section, I right click over the "as_df" property, and it lists a context menu with the option "View Value in Data Previewer", as it was doing before, but when clicking, it shows that error.

When doing the same on other pure dataframes I have seen the second log error. Interesting, there after trying to click on "View Value in Data Previewer" for a second time in the same breakpoint, before continuing, it opened the data preview.

One thing I discovered, if I do in debug terminal t = self.myobject.as_df I can preview the t dataframe, but still not directly from self.myobject.as_df
