Answer: 
I fixed the problem by deleting a python folder that was in the root directory of C:/ which caused installing the package to be ignored and not be installed in the correct directory which is in C:/Users/
This is not a very correct decision, but I had same problem with another libraries. You can be using different python interpreters (in my case it was anaconda) => libraries can be installed in different folders

It was a temporarly solution, but I created new venv

```
pip install virtualenv
mkdir python-virtual-environments && cd python-virtual-environments
python3 -m venv env
source env/bin/activate    # activate venv

```

There you can install all packages for your project, and deactivate it (with ***deactivate***) command
