Hello, while launching the boston house regression app (app 9) I get this error:

KeyError: <class 'numpy.float64'>
Traceback:
File "/home/xxx/anaconda3/envs/stl/lib/python3.8/site-packages/streamlit/script_runner.py", line 332, in _run_script

df = user_input_features()
File "/home/xxx/github/streamlit_freecodecamp/app_9_regression_boston_housing/boston-house-ml-app.py", line 25, in user_input_features
CRIM = st.sidebar.slider('CRIM', X.CRIM.min(), X.CRIM.max(), X.CRIM.mean())
File "/home/xxx/anaconda3/envs/stl/lib/python3.8/site-packages/streamlit/elements/slider.py", line 159, in slider
data_type = SUPPORTED_TYPES[type(value[0])]

It seems there something odd between the format in which data in the sidebar are saved and the way the program expects them?
Any help is appreciated!
Thanks

Hello there I am new to programming entirely. But I found this a little easy so I thought of starting from here. I managed to download and install Anaconda, make a new environment, write the entire code but at last I am having problems with the streamlit app. It says [AttributeError: 'DataFrame' object has no attribute 'close']
The programme is same 2 same. If you could point me into the right direct that would be great
I am attaching snapshot of the issue.

AttributeError: 'DataFrame' object has no attribute 'close'
Traceback:
File "c:\programdata\anaconda3\lib\site-packages\streamlit\script_runner.py", line 337, in _run_script
exec(code, module.dict)
File "C:\Users\shubh\PycharmProjects\pythonProject1\1.py", line 21, in
st.line_chart(tickerDf.close)
File "c:\programdata\anaconda3\lib\site-packages\pandas\core\generic.py", line 5139, in getattr
return object.getattribute(self, name)

nucleotide encoding field is specified without a type; the type cannot be inferred because it does not match any column in the data. this error kept showing for the barchart part!!

When plotting the 2 SHAP figures, the figures appear, but the following warning also appears.

st.header('Feature Importance')
plt.title('Feature importance based on SHAP values')
shap.summary_plot(shap_values, X)
st.pyplot(bbox_inches = 'tight')
st.write('----')

plt.title('Feature importance based on SHAP values (Bar)')
shap.summary_plot(shap_values, X, plot_type = 'bar')
st.pyplot(bbox_inches = 'tight')

PyplotGlobalUseWarning: You are calling st.pyplot() without any arguments. After December 1st, 2020, we will remove the ability to do this as it requires the use of Matplotlib's global figure object, which is not thread-safe.

The temporary solution is to configure the streamlit option:

st.set_option('deprecation.showPyplotGlobalUse', False)

However, is there a solution that does not require disabling deprecation warnings?

For some of the prior examples, like the basketball_app.py, it was easy to determine what to pass as the fig:

st.pyplot(f)

For this streamlit dashboard, which incorporates the SHAP library, what can be passed in as the <fig> in line 81 & 86: st.pyplot(<fig?>, bbox_inches = 'tight')?

Version Reference:
python - 3.10.0
matplotlib - 3.5.1
streamlit - 1.5.1

im getting this error while running the code of streamlit repo (iris classifier )
please tell me why is this throwing up?
