Kernel error

I need to use python3.6 for some applications,
however I encountered the kernel error when running jupyter notebook on the board(PYNQ-ZU),after I installed the python version3.6.9, and soft link to python version3.6.9

I thought that might because I accidentally deleted “/usr/local/share/pynq-venv/bin/python3” by the commands below

sudo rm /usr/bin/python3
sudo rm /usr/bin/pip3

how can I possibly fix it?

Hi @ZI-YIN_Hong,

The easiest solution is to burn the SD card with the 2.7 image again.

Be mindful that Python 3.6 EOL was last December Python |
