                You should install numpy in the environment which is used for your project. Try opening terminal in PyCharm and run pip install numpy.

                You should check in setiings->Project->Project interpreter the environment used for the project. You'll see installed packages there as well.

assume that you're using macOS with pyenv for different python versions.
Take the matplotlib stacked bar graph bar_stacked.py as the example (you could get the .py from  https://matplotlib.org/gallery/lines_bars_and_markers/bar_stacked.html#sphx-glr-gallery-lines-bars-and-markers-bar-stacked-py).
short answer: quickly configure pyenv python as this snapshot shows:
quick config steps
details
open the bar_stacked.py with PyCharm;
check your python environment settings:
2.1 check your python version with your terminal:
ABC-MacBook-Pro:~ ABC$ which python
/Users/ABC/.pyenv/shims/python
2.2 check your pyenv installed pythons
ABC-MacBook-Pro:~ ABC$ pyenv versions
  system
* 3.7.0 (set by /Users/ABC/.python-version)
2.3 confirm the python version you're using, here is Python 3.7.0
ABC-MacBook-Pro:~ ABC$ python --version
Python 3.7.0
3.configure the PyCharm interpreter as follows:
3.1 PyCharm -> Preferences -> Project -> Project Interpreter, you'll see a icon like a gear, click it and choose Add...
3.2 choose Virtualenv Environment on the left
3.3 choose Existing environment on the right, in the pop-up, locate the python i'm using as checked in step 2.1, here is /Users/ABC/.pyenv/shims/python
3.4 you can also check the box Make available to all projects if you want
finally, this example in PyCharm runs like this:
running
