Your gdb is compiled with Python 3.5 bindings.

Either install the dependencies (Keystone, Capstone, Unicorn) for Python 3 or
recompile gdb with python2 bindings.

Okay. Now I have switched to Python 3.5 and I am doing pip3 install keystone but it gives me following error

Collecting keystone

Also, I tried to install keystone from the git repo but its not detected by the gef.

Found the Fix.

You guys need to update the keystone installation steps. For correct information, check Keystone-install

Also, for unicorn installation , you have to do

git clone https://github.com/unicorn-engine/unicorn.git && cd unicorn && ./make.sh && sudo ./make.sh install && cd bindings/python && sudo make install

Yes, I was made aware that there is already a (wrong) package called keystone in pip.
