The file /usr/bin/tor-prompt from the python3-stem RPM has a /usr/bin/python2 shebang, so it won't work unless python2-stem is also installed.
Please switch the shebang to use Python 3.
If anything is unclear, or if you need any kind of assistance, you can
ask on IRC (#fedora-python on Freenode), or reply here. We'll be happy
to help investigating or fixing this issue!
