Issue with View as Dataframe Polars

[8DanB]

I cannot view a polars dataframe using "View as Styled Dataframe" when I try and view a polars dataframe outside of the debugger in Pycharm.

When using the debugger, it works fine. However, I have setup Pycharm to run code line-by-line using the plugin "Pycharm Smart Execute". When I try and view the Styled Dataframe nothing pops up with a polar dataframe.

Hi, can you please provide the following things for me so that I can have a look?

• version of used
  • PyCharm
  • Pycharm Smart Execute
  • Styled Dataframe Viewer
  • polars
• a very simple code snippet to reproduce the problem
• a detailed description about the steps/shortcuts used in your workflow
  • Since I have not yet used Pycharm Smart Execute, a detailed description would be very helpful. For example, I have no idea what exactly is meant by: I have setup Pycharm to run code line-by-line using the plugin "Pycharm Smart Execute".

PyCharm version: PyCharm 2023.3.3 (Community Edition) PyCharm Smart Execute: installed plugin 0.3.2 Guo Ci Python Styled DataFrameViewer: 0.14.0 cms.rendner polars: 0.20.7

Snippet: `import polars as pl

data = {'Name': ['Alice', 'Bob', 'Charlie'], 'Age': [25, 30, 35], 'City': ['New York', 'San Francisco', 'Los Angeles']}

df = pl.DataFrame(data)

print(df) `

Description: Smart Execute allows me to run code line-by-line in Python, as opposed to using the debugger. I have keymaps setup so "CTRL + Enter" will "Execute cell in console, move to next code region" within the Settings -> Keymap section of Pycharm.

I am an R-user -- R studio has the functionality to run a line of code, inspect result, then another line, inspect, etc. I have been able to mirror this with Pycharm, however I am not able to view the Dataframe when I want to see it in the variable explorer.

Thank you very much. I have managed to reproduce the described behavior. The problem is independent of polars, it also exists for pandas.

My plugin requires an existing debugSession to work correctly. In your scenario the plugin can't get a debugSession. PyCharm returns null for XDebuggerManager.getInstance(project).currentSession.

The action Evaluate Expression, provided by PyCharm, is disabled in case no debugSession is available. I will also disable my View as Styled DataFrame action in this case so that it is clear to users.

Thank you for reporting the problem.

@8DanB I have released a new version (v0.15.0) that also works with the Python Console.
