Here is the English translation of your previous question:
I am using the Pynq Z2 board and the Pynq 2.5 version image with Vivado 2018.3. When I run it on Jupyter, I get the following error: “Could not find IP or hierarchy Conv_0 in overlay.” However, the overlay is already loaded on the board, and I can see the IP core information using the Vivado hardware manager. I don’t know what the problem is, and this issue has been bothering me for a week.
