I am trying to setup evalai-cli using pip, but i am facing problems during setup when i try to run
pip install evalai
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?

I have installed lxml using easy_install lxml & www.lfd.uci.edu
but still the problem remains
I am on windows 10 64 bit running python 38

Try to go to https://www.lfd.uci.edu/~gohlke/pythonlibs/
then you download the file lxml-4.4.2-cp38-cp38-win_amd64.whl
then open the Command and navigate to the folder containing the file lxml-4.4.2-cp38-cp38-win_amd64.whl
then run the Command pip install lxml-4.4.2-cp38-cp38-win_amd64.whl
