Vitis-AI Integration : Setup error @ Edge hardware setup

kvaju.454 · January 28, 2021, 12:59pm

Hi @jtuyls / @mak ,

I am trying to setup the DPU-PYNQ on target device with fresh and I have followed the steps which was mentioned here.

Download the Pynq v2.5 image for your target (use Z1 or Z2 for Ultra96 target depending on board version) Link to image: Release Glasgow Release · Xilinx/PYNQ · GitHub
Follow Pynq instructions for setting up the board: pynq setup
After connecting to the board, make sure to run as root. Execute su
Set up DPU on Pynq by following the steps here: DPU Pynq setup
Run the following command to download the DPU bitstream:

python3 -c ‘from pynq_dpu import DpuOverlay ; overlay = DpuOverlay(“dpu.bit”)’

Check whether the DPU kernel is alive:

dexplorer -w

At step 4, I am seeing following error while running the “python3 install pynq-dpu” command

Error:

Collecting pynq-dpu

looks like I am missing something here, Can you please help on this?

Note:

Now I have tried with and without 2.6 upgrade step and still I am seeing same error.
Last time somehow I was able to build and run resnet50 model on target device.

Thanks and Regards, Raju

Hi @mak / @jtuyls ,

Above issue was resolve with following changes in the Set up DPU on Pynq phase.

git clone --branch v1.1.2 --recursive --shallow-submodules https://github.com/Xilinx/DPU-PYNQ.git
cd DPU-PYNQ/upgrade
sudo make
sudo pip3 install pynq-dpu==1.1.2

Kindly update these changes into Vitis-AI Integration TVM document .

Thanks and Regards, Raju

Thanks for reporting this issue, @kvaju.454 ! Your fix would also work but I updated the instructions to use the Pynq 2.6 image to make the latest pynq-dpu version work, see this PR: [BYOC][VitisAI] Fix issue in Vitis AI codegen out tensor names matching & update docs and docker by jtuyls · Pull Request #7350 · apache/tvm · GitHub.
