Vectorbt documentation code examples throws unsupported error.

[timqaa]

Hello everyone, Im really sorry for kinda clickbait title, but I really cant find similar issues and dont know what to do. Hope on your kindness guys Im using vectorbt like this (the simplest example of usage)

import vectorbt as vbt

price = vbt.YFData.download('BTC-USD').get('Close')

pf = vbt.Portfolio.from_holding(price, init_cash=100)
pf.total_profit()

and getting the "unsupported error" when its going to nb.simulate_from_signal_func_nb. I tried already everything but resuls are the same. Nothing works to me. Please explain what Im doing wrong

P.S ofc I checked versions of packages and tried to reinstall them again. Still nothing... Current versions Python 3.11.0b4, vectorbt 0.26.1, numba 0.59.1, numpy 1.26.4 . Oh, and Im using Windows 10 x64

The biggest thank you in advance!

@timqaa it seems like you are using a beta release of Python. Numba may not be compatible. Can you use a non-beta release instead?
