Create new app issue

I’m deploying the new app i got error this “ValueError: dtype=‘numeric’ is not compatible with arrays of bytes/strings.Convert your data to numeric values explicitly instead.“but I change the code when I run streamlit server in my local machine the output will be show,but deploying the error I got errors like this” UserWarning: X does not have valid feature names, but LinearRegression was fitted with feature names” , please help me out and also provide my git repo link

There were some issues:

  • you feed strings instead of numeric values into the predictor
  • requirements outdated
  • unnecessary packages and imports

See my pull request on github, streamlit app should work now:

Hello @vinod_kumar and @Franky1,
I am also getting the same error. Could you please help me out with this?
What did you do?

Can you send the git repository link

Here is my GitHub link: Multiple Diseases Predictor
Here are the screenshots of the error:

Did yo get the answer for the error .
I am also facing same issue please help

In the numerical column your entered categorical data that’s why you get error

Where I did not understand

You need to read the traceback to figure out where in your code is the statement that triggers the error.

In heart disease prediction, your input should be numeric, but in your app, it will be categorical, so they get errors. Replace the text_input feature with a slider and you will get it. I will also share my git link for reference.

Can u please provide conta t details

this is my file
please check this where is issue

code for Prediction

creating a button for Prediction

if st.button(‘Heart Disease Test Result’):
heart_prediction = heart_disease_model.predict([[age, sex, cp, trestbps, chol, fbs, restecg,thalach,exang,oldpeak,slope,ca,thal]])

if (heart_prediction[0] == 1):
heart_diagnosis = ‘The person is having heart disease’
heart_diagnosis = ‘The person does not have any heart disease’


use st.number_input instead of st,text_input

Use st.number_input

You can check here GitHub - MutegiMk/MultipleDiseasesPrediction: This App Predict Three Different Diseases

use st.number_input
