I have tried updating and reinstalling the python3-numpy and all the other ways to rectify this issue. what should i do ? please help !!

Answer 1

Restart your computer. If you installed numpy with pip install numpy , it installed on your default python version. Try to execute it with python3

Answer 2

You have installed the python3-numpy package from the default Ubuntu 18.04 repositories. Enter into command mode with the -c option of python3 to check if you can indeed import numpy in python3.

python3 -c "import numpy"

Another way of making sure that you are running python3 is to start the python3 interpreter using the command python3 and then run import numpy from the python3 prompt.
