install CNTK on server

I am installing cntk on my server. (Only CPU version) python version is 3.6.6

mpirun -V

mpirun (Open MPI) 3.1.1

I follow the instructions here and it is ok.

pip install https://cntk.ai/PythonWheel/CPU-Only/cntk-2.7.post1-cp36-cp36m-linux_x86_64.whl

Then, I run Python and import cntk. But there are some error as below.
