Revision history [back]
A common mistake is to be using a different python executable or virtual environment than the one that you expect. To see if this is the case, run a python shell both inside Wing and from the command line and compare the initial message with the version & build information and sys.path. If these differ, you're probably not using the same python. How to change the python that Wing uses is documented in https://wingware.com/doc/proj/project-properties
If you are using the python that you expect, please verify that they can be imported when run from the command line. They should be available if you installed with pip or the equivalent conda command; if you installed some other way, please tell us how you installed them.
