Error using edivisive

[angus-c]

Hi!

When I try to run a simple e-divisive example I'm getting a dependency error. I'm new to python package infrastructure so it's possible I did a bad install (I used pip)

Code

from signal_processing_algorithms.energy_statistics import energy_statistics
series = [1,2,3,4]

change_points = energy_statistics.e_divisive(series, pvalue=0.01, permutations=100)

Error

Python 3.8.2 signal-processing-algorithms 2.0.0

I'm also getting the same thing, any solution?

[angus-c]

IIRC I removed the C++ portion of the code.

Probably related to poetry 1.4. See https://github.com/python-poetry/poetry/issues/2740#issuecomment-1447608715 for details. Probably the solution will be to just include generate-setup-file = true in the pyproject.toml

I got the same error.

Downgrade the version of poetry to 1.3.2 can fix this, then run:

poetry build

It will generate a whl package corresponding to the python version in the current directory
