I am using PYNQ v2.7 to build it for zedboard. Xilinx Vitis 2020.2 and petalinux 2020.2 using to build.

I am using the prebuilt board-agnostic image to build, but I am getting errors shown below.

Hello welcome,

Please check this build instruction on PYNQ 2.7:

Hey, I will try your method without using Vagrant. Thank You

I want to ask one more thing before “make” the command can I install PyTorch and then build? Will that work? Or can we add PyTorch command in the script\_host.sh ?

Please, if you know any alternative, please tell me how to install PyTorch.

Thank you for the help

Hello,

For any package related to the PYNQ, I will highly suggest you do it after the image is bootable and boot into the PYNQ ubuntu and install it. rather than using the virtual environment on Linux to install it.  
As you screw up any thing will result in rebuild the image again while if you had a image built and you screw up the installation you can easily reimage the SD card.

It looks like your dtsi had some issue.  
What is your base overlay project?  
Empty Zynq or there are additional device that had set?

Yeah, it is fixed. There was a problem with the board file. In the project\_bsp folder, I put zedboard xsa in that folder, and after that, I build it, and it was working.
