When using a bool column gr.Datafame the dtype of the pandas dataframe changes from bool to object #11492
Description
Describe the bug
- I use a
gr.Dataframewith one column configured with the datatypeboolto display checkboxes. - I toggle one checkbox
- The pandas dataframe retuned from the input-event contains at the toggled cell a lower-case written boolean value (
true|false) insted of the correct written value in Python (True|False). Further thedtypeof the colum of the pandas dataframe changes frombooltoobject

Reproduction
import gradio as gr
def input_received(df_input):
print("Input received:\n", df_input, df_input.dtypes)
return str(df_input), str(df_input.dtypes)
df_data = pd.DataFrame({"A": [1, 2, 3, 4], "B": [True, False, True, False]})
with gr.Blocks() as demo:
with gr.Row():
dataframe = gr.Dataframe(headers=["A", "B"], value=df_data, interactive=True, show_row_numbers=True,
static_columns=[0], datatype=["number", "bool"])
with gr.Column():
output_table = gr.Textbox(label="Table", value=str(df_data))
output_dtypes = gr.Textbox(label="Table Data Types", value=str(df_data.dtypes))
dataframe.input(input_received, inputs=dataframe, outputs=[output_table, output_dtypes])
