acor module error

[cmarsan]

Hi, I'm pretty new to python and am having an issue with acor that I thought I installed successfully (tried both pip install and git clone). I'm getting pretty similar errors as those listed in issue #4, and I need acor for a separate Python algorithm. I have Python 3.5.2 through Anaconda.

import acor
acor
<module 'acor' from '/localdir/anaconda3/lib/python3.5/site-packages/acor/init.py'>
import numpy as np
a= np.random.rand(500)
acor(a)
Traceback (most recent call last):
File "", line 1, in
TypeError: 'module' object is not callable

Any tips?

Have you tried calling the acor function instead of the module? The usage is given here: https://github.com/dfm/acor#usage

Also: I'd recommend checking out the autocorr module in emcee http://dan.iel.fm/emcee/current/api/#autocorrelation-analysis because it's a bit more reliable. acor will be marginally faster but it will probably only be worth it if you need to compute many autocorrelation times on datasets with billions of points.

If I call the acor function, I get:
AttributeError: module 'acor' has no attribute 'acor'

[dfm]

Sounds like it didn't get installed then. How did you install the package?

[cmarsan]

pip install acor

[dfm]

I dunno then. Try cloning from github and installing that way. No one has touched this project in 3 years so it's definitely use at your own risk! I'd still recommend the algorithm in emcee before this one.

This is the same issue as #4. My workaround (for python3.5 and newer) is to replace in acor/acor.py

import _acor

by

import acor._acor as _acor

Then the acor function can be used after importing as import acor.acor as acor.

Seems the pip package installed by

pip3 install acor

(states to be acor-1.1.1) is out-dated, the Github code is more recent and fixes this?
