Streamlit selectbox use Array list

What is your plot_predictions function definition? I’m not clear since you are passing in both the output from your selector (model_predict) along with another hard-coded selection (one of the three choices in each of the three calls to your plot function).

Are you converting back to the pointer to your lists within the plot_predictions function? If not, you would need to give it (for example) preds['SVM Predictions'] instead of the string 'SVM Predictions'.
