When using the 'Quick Documentation' (CTRL+Q) feature in the editor, PyCharm says it can't find any documentation for functions under the caret from the Pandas library (ie. pandas.read_csv). However, if I open a python console with Tools -> Run Python Console and try the same thing, PyCharm is suddenly able to find documentation via CTRL+Q. Most other modules I use don't have this problem. Why am I able to see Pandas' documentation in the console but not in the editor?
