Dataframe examples problem #10723

caglarari · 2025-03-04T08:37:49Z

Describe the bug

The code below that uses Gradio dataframe with pandas dataframe examples used to work but I tried it on Hugging Face & it doesn't work anymore. It doesn't work with an older Gradio version 3.50.2 either. When I tried it with version 3.50.2, Gradio treated the first row of the pandas data frame as string / header but it shouldn't since Xhpd=pd.read_csv("data_NB.csv",header=None)

Any idea how can I fix this problem?

plt.rcParams['figure.figsize'] = [10, 10]
plt.rcParams['figure.dpi'] = 100

yhpd=pd.read_csv("labels_NB.csv",header=None)

Hi @caglarari can you provide a minimal example with correctly formatted code we can use to reproduce the issue? The example provided here is not minimal and not formatted.

caglarari · 2025-03-04T09:57:27Z

Hi,
I added an app.py file (as app.txt). This works fine on my machine with the same configuration given in the added requirements.txt file. It still doesn't work & gives a runtime error on Hugging Face

abidlabs · 2025-03-04T20:38:35Z

Hi @caglarari would you please be able to provide a minimal example that we can use to reproduce the issue above? See: https://stackoverflow.com/help/minimal-reproducible-example
