TypeError: 'NoneType' when running pycbc_inspiral for gw150914

[BeltMarDani]

Hi, I am trying to reproduce results from pycbc/examples/gw150914 via command lines and instead of running the notebook I just run pycbc_inspiral from the terminal. Appears that, with the same arguments as the ipynb example, I am returned:

I installed PyCBC following the guide and I am running the code in my own python virtual environment. Thanks.

@BeltMarDani Thanks this example may be out of date since the options to the code have evolved somewhat.

In the meantime, here's an example we include as part of the CI so I can guarantee works.

Hi, at least for me, this isn't working too.

>> [lun may 20 12:28:12 CEST 2024] Running pycbc inspiral fftw:openmp with 16 threads
usage: 
pycbc_inspiral: error: unrecognized arguments: --fftw-threads-backend openmp

If I remove the problematic argument, then the error remains:

usage: 
pycbc_inspiral: error: Backend fftw is not available

If else I change --fft-backends to numpy , then the error is:

Can you check if the code is working for you? Perhaps it is some issue concerning my PyCBC installation or something else.
