Hi there,

Have you gone through other setup steps outlined on the getting started page? Like running xlnx-config.sysinit, before installing Kria-PYNQ?

Thanks
Shawn

Hello,
I have followed every setup step as outlined on the getting started page.

Thanks

Hi @Nilz,

Did you start from a fresh SD card image? Or did you run something before trying to install PYNQ?

I installed OpenCV before installing PYNQ.

Can you provide the exact command(s) so we can try to reproduce?

7

For installing OpenCV, I used the following command.

sudo apt-get install libopencv-dev python3-opencv

One more thing I almost forgot I tried to install Anaconda 3. I installed the dependencies using the following command, but the installation failed.

sudo apt-get install libgl1-mesa-glx libegl1-mesa libxrandr2 libxrandr2 libxss1 libxcursor1 libxcomposite1 libasound2 libxi6 libxtst6

This is the link for Anaconda
Following this, I tried to install PYNQ.
Sorry for missing out on a vital piece of information.

Hi,

At this point I would suggest you install PYNQ in a fresh Ubuntu image.

Please share the log of the failed Anaconda installation if you have it.

Mario

I dont have the failed anaconda installation log. I’ll do as you suggest.

Thanks
Nilanjan
