Can anyone help me?

fbprophet version 0.7.1(it's the latest one available)

python version from conda cmd:

• python
• spyder
• miniconda

• Because the holidays package has a bug – roganjosh Commented Feb 2 at 11:31
• do i really need the holidays package? how to "not use it" ? – noobsee Commented Feb 2 at 11:31
• holidays is being called by fbprophet so, no, you can't remove the dependency. You could try upgrading either/both of the packages and see whether that helps. I'm curious about the source code now because TypeError: 'ABCMeta' object is not subscriptable seems very odd from what looks like a type annotation – roganjosh Commented Feb 2 at 11:34
• What version of python are you using? – roganjosh Commented Feb 2 at 11:36
• I attached my python script on the question, or what you need is the source code from holiday_base.py file? Anyway, I already use latest fbprophet version 0.7.1 (just added the screenshot on my question) – noobsee Commented Feb 2 at 11:40

1 Answer 1

The root cause for the issue is unclear to me, however, to unblock you, you could consider installing the prophet package rather than fbprophet.

Note that fbprophet corresponds to older versions of the lib, prior to v1.0.

V1.0 was released in 2021 and any other versions launched since then are available on the prophet package (ref).
