Hi, dear PYNQ developers,
If we turn off the Jupyter to offload the CPU on ZCU-104, can our Python code still work as well which loads the FPGA bitstream image and perform register configuration of the hardware accelerator on the ZCU-104? It is assumed that we use command mode to execute the Pyhon code on PYNQ ZCU-104.

BTW, is it related to the following problem?
xilinx@pynq_sdu:~/pynq/prj_tst/int_add $ sudo python3.6 int_add.py
