I am following the tutorial – https://learn.microsoft.com/en-gb/azure/ai-services/openai/how-to/assistant#supported-file-types

I created a notebook in Fabric.

I downloaded the packages using the following commands in a cell

%pip install openai
%pip install openai --upgrade
%pip install pillow

In the last step, when I run the code to open the sinewave.png file,

from PIL import Image

# Display the image in the default image viewer
image = Image.open("sinewave.png")
image.show()

I get the following error:

    ---------------------------------------------------------------------------

    640 except KeyError as e:

The above exception was the direct cause of the following exception:
