Could not import the C extension for the projected correlation function. #316

Open suhani0603 opened 7 months ago

suhani0603 commented 7 months ago

I installed corrfunc using the instructions provided in https://corrfunc.readthedocs.io/en/master/install.html

--- this is my script to compute the correlation function

import numpy as np import Corrfunc from Corrfunc.theory import * from Corrfunc.theory.xi import xi

file_halos = np.loadtxt('m_xyz.dat')

boxsize=1024 nthreads = 4 x = file_halos[:,1] y = file_halos[:,2] z = file_halos[:,3]

rmin = 0.1

rmax = 20.0

nbins = 20

rbins = np.logspace(np.log10(rmin), np.log10(rmax), nbins + 1)

results_xi = xi(boxsize, nthreads, rbins, x, y, z)

I am getting the following error: Could not import the C extension for the projected correlation function.

I am using Python 3.9.18 numpy 1.26.4 conda 24.3.0

Thank you in advance :)

Thank you for using Corrfunc and also reporting the issue!

There are a few things that might be going wrong but will need a bit more info to check. Will you please provide the following:

That should (hopefully) give us some insight into what might be going wrong

Dear Mandeep, Thank you for your reply. Here are the details:

Corrfunc is installed in my system. There is no issue when I import the library. I only obtain this problem with importing the C extension. I confirm that I am using the same python in which I am trying to import Corrfunc into.

  • what operating system and compiler are you using
  • the output of compiler —version
  • The output of python —version
  • the entire output from python -m pip install -e . —verbose (might want to redirect to a log file and then attach the log file)
  • confirm that the python used in installing is the same python you trying to import Corrfunc into

That should (hopefully) give us some insight into what might be going wrong

@suhani0603 GitHub doesn't allow attachments over email, unfortunately. Could you attach the log file directly to a comment on this issue?

manodeep commented 7 months ago

@suhani0603 Did you still need help on this?

suhani0603 commented 6 months ago

Dear Manodeep, Thank you for your email, and apologies for the late reply. I had my phd defense so I was completely focussed on preparing for that.

I have not yet looked into this, I will get back to you as soon as possible.

Regards Suhani Gupta
