I googled how to install the fbprophet package, but the top result is how to install prophet. What is the difference between the two packages? Are they the same?
It's by the same devs. Seems it was just a name change.
Prophet is on PyPI, so you can use pip to install it. From v0.6 onwards, Python 2 is no longer supported. As of v1.0, the package name on PyPI is "prophet"; prior to v1.0 it was "fbprophet".
