I am trying to build an image for Zedboard using PYNQ. However, I am getting the following error:

I am using Vivado, SDK and Petalinux 2018.2 and PYNQ v2.3 downloaded from Branch: image_v2.3 at GitHub - Xilinx/PYNQ: Python Productivity for ZYNQ
I am not using any prebuilt image file and using only the Petalinux BSP avnet-digilent-zedboard-v2018.2-final.bsp download from Xilinx.
I created a folder Zedboard inside which I put the BSP file and a Zedboard.spec file. The contents of the Zedboard.spec file are:
ARCH_Zedboard := arm
BSP_Zedboard := avnet-digilent-zedboard-v2018.2-final.bsp
BITSTREAM_Zedboard :=
STAGE4_PACKAGES_Zedboard := pynq boot_leds ethernet
After I got this error the first time, I deleted the bionic.arm.stage2.img file and ran
make BOARDDIR=/home/nairit/PYNQ/PYNQ_v2.3/boards/MyBoards
again but with the same resulting error.
I tried solution for SLEEP as well from Rebuild Pynq image failed but with no success.
Can someone please help?
The Makefile expects to be run from inside a git repository rather than the downloaded source files. Can you try cloning the repository, checkout out the branch you want and then running make?

Thanks Peter. Can I copy the contents of my old sdbuild folder to the new cloned repo and start the make process again?? Both are v2.3
We have limited data connectivity here and it takes hours just to download the files need for the build process.
One thing that might be of interest to you is the PYNQ_UBUNTU_REPO environment variable. We don’t really document it as it’s more for internal use but you can use that to pull the Ubuntu packages from a local repository rather than the internet.
We internally have our own build of the Ubuntu packages which sit in a folder in a manner like this which then get used by setting PYNQ_UBUNTU_REPO="copy://path/to/repo". This might help your bandwidth usage.

Thank you very much Peter.
I am running the build process again.
Having the ubuntu repo in a local folder seems like e good idea. I am new to Linux platform. So don’t know how to set environment variables in linux. May be will learn with time.
Thanks Peter. Cloning from git repo solved it. I can access the zedboard via ethernet.
However, I now get errors in python when running the jupyter notebooks. When I run the cell:
from pynq import PL
from pynq import Overlay
ol = Overlay(PL.bitfile_name)
I get the following error:

I upgraded pip from 9.x.x to 20.0.2. Then ran:
!pip3 install pandas
But again this error:

I tried upgrading Cython:
!pip3 install --upgrade
But again got this error:
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

ERROR: Cannot uninstall 'Cython'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
The version of pandas we use on our images is 0.22. We’ve hard-coded this in newer versions of sdbuild to avoid these problems. Try running
sudo pip3 install pandas==0.22.0

Thanks Peter. I did as you suggested. But I am stuck in the installation process. Been more than an hour now.
Did I do something wrong?
UPDATE: It completed installation of pandas after a couple of hours.
