A heads-up for those who are using vivado 2023.2

[qcsui]

I found that when running the sample's make project command, a error can be occurred.

    zynet.makeXilinxProject('myProject1','xc7z020clg400-2')

    python mnistZyNet.py
Minimum bits required for integer representation of Weight Values 3

This is due to lack of "path" keyword. Find the where your install of vivado 2023.2 tcl shell was installed and add it to your windows Path. Then change the installed zynet's source code to from Vivado to vivado, because in 2023.2 the name for vivado tcl shell is Xilinx\Vivado\2023.2\bin\vivado.bat
