How to install CVXOPT in VS code

Trying to install CVXOPT in VS code it fails every time ,so far I have tried installing using wheel file, tar file, just pip install, pip install --user and others, but fails every time with the same error that I don't have an idea of. (env) PS C:\Users\paseckat> python pip install cvxopt

The error I am getting:

Processing c:\users\paseckat\cvxopt-1.2.5.tar.gz

  Running setup.py install for cvxopt ... error

WARNING: You are using pip version 19.2.3, however version 20.2.3 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Not sure what this really means :

Would someone be able to help or seen this before?

Solution

I needed install manually the library.

I checked my python version: in command line: python --version (My version is 3.8.6)
I updated numpy to the latest version: 1.19.2

get numpy version from command line: python -c "import numpy; print(numpy.version.version)"
pip install numpy --upgrade

I downloaded numpy‑1.19.2+mkl‑cp38‑cp38‑win32.whl

1.19.2: this is the numpy version
cp38: this is the Python version, if you have different version, look for your other version of numpy+mkl

I downloaded cvxopt‑1.2.5‑cp38‑cp38‑win32.whl

cp38: this is the Python version

Install manually: First have to install numpy+mkl

cd < pathway of the files >
python -m pip install numpy-1.19.2+mkl-cp38-cp38-win32.whl python -m pip install cvxopt-1.2.5-cp38-cp38-win32.whl
