I think there is a bug with the get_tempo_changes() function. It is not loading the tempo changes properly. Here is an example:
mid = pretty_midi.PrettyMIDI(midi_file="Undertale_PC_Undertale_Snowy.mid")
mid.get_tempo_changes()
output:
(array([ 0. , 15.73798337, 15.73894393]), array([60.99519764, 60.99966247, 60.99519764]))
But when I open the midi file on a midi player (e.g. GarageBand), the first ~60bpm tempo change only happens around the 5th bar. Here is a screenshot:
If I save the midi file with pretty_midi (mid.write("Undertale_PC_Undertale_Snowy._copy.mid")) and open it with the same midi player, this is the output:
Here are the midi file and the screenshots for reproduction:

pretty_midi 0.2.9 and python 3.7
