When I had a similar problem (couldn't import numpy in Pycharm but on cygwin console), it turned out that cygwin was using a different interpreter as PyCharm.

In PyCharm I had configured the interpreter from C:\Program Files\cygwin\usr\bin\python. In contrast, cygwin was using /bin/python. In PyCharm click File > Settings > Project: yourProjectName > Project Interpreter, click on "Add local" and find the interpreter used by cygwin (in my case C:\Program Files\cygwin\bin\python).

Then open the Python Console in PyCharm via View > Tools Windows > Python Console and try your import statement.
