Hi Nitish This is a python 2/3 issue. The toolflow has been upgraded to use python 3. Most people are running it in a virtual environment and install the requirements.txt in the root of mlib_devel. Assuming you are using the latest version of mlib_devel in casper-astro.
Hope this helps. Regards Wesley On Tue, 19 Nov 2019, 7:03 PM Nitish Ragoomundun, < nitish.ragoomun...@gmail.com> wrote: > Hi, > > I was using Matlab R2017b and Vivado 2016.4 until recently.
