AttributeError: 'list' object has no attribute 'copy'

[ANUBHAB KHAN]

Hi,

I am trying to run the following model: 

>>> import numpy

>>> from numpy import array

>>> import dadi

>>> data = dadi.Spectrum.from_file('CONTINENTAL.fs')

>>> ns = data.sample_sizes

>>> pts_l = [40,50,60]

>>> func = dadi.Integration.three_pops

>>> func_ex = dadi.Numerics.make_extrap_log_func(func)

>>> params = ([1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0.5, 0.5, 0.5, 1, 0])

>>> model = func_ex(params, ns, pts_l)

However I get the following error

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "build/bdist.linux-x86_64/egg/dadi/Numerics.py", line 294, in extrap_func

  File "build/bdist.linux-x86_64/egg/dadi/Integration.py", line 330, in three_pops

AttributeError: 'list' object has no attribute 'copy'

I don't understand this error. Can someone please help?

Thanks

Integration.three_pops is not a demographic model. You’ll need to write a custom model if you’re working with more than two populations. Please see the dadi manual for more details.

Best,

Ryan
