UnboundLocalError：无法访问未与值关联的局部变量“数据”[已关闭]

Question

该函数采用输入数据来预测输出

def build_model(input_data):
    # Reads in saved regression model
    load_model = pickle.load(open('alpha-synuclein_model.pkl', 'rb'))
    # Apply model to make predictions
    prediction = load_model.predict(input_data)
    st.header('**Prediction output**')
    prediction_output = pd.Series(prediction, name='pIC50')
    molecule_name = pd.Series(load_data[1], name='molecule_name')
    df = pd.concat([molecule_name, prediction_output], axis=1)
    st.write(df)
    st.markdown(filedownload(df), unsafe_allow_html=True)

在回溯中，它突出显示了 load_data[1] 部分
