you can restart your app first to see what will happen.
if result is same,
maybe because your data is very big or you used a lot of circle methods in code.

The result is same and there is no circle in my code ,but I insert a lot number_input (about 7 per page).Is it makes my app just keep running forever?Here is part of my code

if page == '所需资源预测':
        st.write('# 所需资源预测')
        st.write('***')        
        column1,column2=st.columns(2)
        with column1:
            st.write('### 输入')
            ExportVolume=st.number_input('出库量',min_value=0,help='请输入一个整数作为出库量')
            ImportVolume=st.number_input('入库量',min_value=0,help='请输入一个整数作为入库量')
            num_of_position=st.number_input('收发货位总数',min_value=1,help='请输入一个整数作为收发货位总数')
            t_in=st.number_input('单箱入库时间（分钟）',min_value=0.0,value=2.0,help='请输入一个浮点数作为单箱入库时间（单个箱头的入库用时）')
            t_out=st.number_input('单箱出库时间（分钟）',min_value=0.0,value=2.0,help='请输入一个浮点数作为单箱出库时间（单个箱头的出库用时）')
            T_Consuming=st.number_input('作业耗时（分钟）',min_value=0.0,help='请输入一个浮点数作为作业耗时')
            num_of_ccs,position_for_export,position_for_import=ResourceRequired(ExportVolume,ImportVolume,num_of_position,t_in,t_out,T_Consuming)
        with column2:
            st.write('### 输出')
            st.metric("所需叉车手",str(num_of_ccs))
            st.metric('所需发货位',str(position_for_export))
            st.metric('所需收货位',str(position_for_import))

check this function, no result because ResourceRequired did not return values.

num_of_ccs,position_for_export,position_for_import=ResourceRequired(ExportVolume,ImportVolume,num_of_position,t_in,t_out,T_Consuming)

Finally,I konw what happend.It is those number_input that make my app keep rerunning.Now I rewrite my code and the problem solved.Thanks for your help and here is part of my new code

if page == '所需资源预测':
        st.write('# 所需资源预测')
        st.write('***')        
        column1,column2=st.columns(2)
        with column1:
            st.write('### 输入')
            ExportVolume=st.number_input('出库量',min_value=0,value=1,help='请输入一个整数作为出库量')
            if not ExportVolume:
                st.stop()    #stop the app to rerun
            ImportVolume=st.number_input('入库量',min_value=0,value=1,help='请输入一个整数作为入库量')
            if not ImportVolume:
                st.stop()
            num_of_position=st.number_input('收发货位总数',min_value=1,value=1,help='请输入一个整数作为收发货位总数')
            if not num_of_position:
                st.stop()
            t_in=st.number_input('单箱入库时间（分钟）',min_value=0.0,value=2.0,help='请输入一个浮点数作为单箱入库时间（单个箱头的入库用时）')
            if not t_in:
                st.stop()
            t_out=st.number_input('单箱出库时间（分钟）',min_value=0.0,value=2.0,help='请输入一个浮点数作为单箱出库时间（单个箱头的出库用时）')
            if not t_out:
                st.stop()
            T_Consuming=st.number_input('作业耗时（分钟）',min_value=0.0,value=60.0,help='请输入一个浮点数作为作业耗时')
            if not T_Consuming:
                st.stop()
            num_of_ccs,position_for_export,position_for_import=ResourceRequired(ExportVolume,ImportVolume,num_of_position,t_in,t_out,T_Consuming)
        with column2:
            st.write('### 输出')
            st.metric("所需叉车手",str(num_of_ccs))
            st.metric('所需发货位',str(position_for_export))
            st.metric('所需收货位',str(position_for_import))
