Bug 1383513

Hmm, strange, but I am unable to reproduce. I tried on two different machines. The events.py is installed by the rtlsdr-scanner package and the Event class is there and I can also run the scanner without problem. Maybe your rtlsdr-scanner installation is damaged, try:
$ rpm -qV rtlsdr-scanner

or maybe, there is an events.py from different package that loads instead (but this would be even more strange), please provide output of the:

$ python -v /usr/bin/rtlsdr_scan

That was it, there's another package called events:

# python -v /usr/bin/rtlsdr_scan 2>&1 | grep events
import events # directory /usr/lib/python2.7/site-packages/events
# /usr/lib/python2.7/site-packages/events/__init__.pyc matches /usr/lib/python2.7/site-packages/events/__init__.py
import events # precompiled from /usr/lib/python2.7/site-packages/events/__init__.pyc
# /usr/lib/python2.7/site-packages/events/events.pyc matches /usr/lib/python2.7/site-packages/events/events.py
import events.events # precompiled from /usr/lib/python2.7/site-packages/events/events.pyc
    from events import Event
# cleanup[1] events
# cleanup[1] events.events

# sudo pip uninstall events
Uninstalling Events-0.2.1:
[...]

# rtlsdr_events
<gui launches>

Is there a way to allow the Events package to be installed from pip alongside rtlsdr-scanner and its internal events module?

Thanks for info.

Mixing distribution RPM with 3rd party package manager (PIP) is IMHO unsupported.

Events is not provided by any Fedora RPM, so there is nothing to fix:
$ dnf provides '/usr/lib/python2.7/site-packages/events/*'

I think the main problem is that the 'events' you use imports events.py in its __init__.py. Why it does it? But this is really not Fedora bug. The rtlsdr-scanenr package use correct import which should correctly utilize loading paths, i.e. there is nothing to fix.

Incorrect, hmm, interesting that it doesn't work with the default paths, I will check it.

https://docs.python.org/3/whatsnew/2.5.html#pep-328-absolute-and-relative-imports

So the default behaviour changed in Python 2.7 to absolute imports. While there is currently no conflict at the moment with distribution packages it maybe worth to fix it, reopening.
