Import error.Module not found error cv2.No module named cv2.Cant install open cv

Hello.I cant install open-cv in python 3.6.I need to import cv2, but i have module not found error: no module named cv2.Sudo apt-get install python-opencv and sudo apt-get install python3-opencv didnt help.
pip install opencv-python command dint help too:
Building wheel for opencv-python runs forever.

How can i fix it and import cv2?Maybe i can install specific version of open cv for python 3.6?
Because ,in my point of view, problem in python 3.6.Because, I installed open-cv in new venv with python 3.7.1 without any problems by: pip install opencv-python.Building wheels infinite for python 3.6 only.

even imhaving this error . Not sure about solution. Please reply if u get one:(

I probably have solution for you, but not for me.
You can create anaconda env with python version 3.7.1 and activate it.
Further follow the steps:

  1. pip install --upgrade pip
  2. pip install jupyterlab
    3.pip install opencv-python
    import cv2

But i also need pytorch,so i cant use that instruction, because there is no pytorch for python 3.7.1.
Do you know how to create anaconda env?

Actually im not able to install opencv in Pycharm community edition. My projects require pycharm only to develop. Anyways thanks for your reply:)

I found specific version of opencv and installed it [python3 -m pip install opencv-python== --verbose].Now i have all necessry components to execute my programm on GPU.
