How can I install this library on a computer with only CPU?

[zhong-yy]

The following error occurred when I ran python setup.py build_ext

/bin/sh: 1: nvcc: not found
make: *** [Makefile:49: fast_matched_filter/lib/matched_filter_GPU.so] Error 127
Could not build GPU code

I was able to install using pip install git+https://github.com/beridel/fast_matched_filter. However, when I run import fast_matched_filter as fmf, the following error occurs,

Matched-filter CPU is not compiled! Should be here: [/miniconda3/envs/my_env/lib/python3.10/site-packages/fast_matched_filter/lib/matched_filter_CPU.so]
Matched-filter GPU is not compiled! Should be here: [/miniconda3/envs/my_env/lib/python3.10/site-packages/fast_matched_filter/lib/matched_filter_GPU.so]

I think I've found the solution. ls ~/miniconda3/envs/my_env/lib/python3.10/site-packages/fast_matched_filter/ showed that there was not a lib directory there. Then, I ran make python_cpu, and mv the so library to the directory of my conda environment:
mv fast_matched_filter/lib ~/miniconda3/envs/my_env/lib/python3.10/site-packages/fast_matched_filter/lib

I'm having this same issue or a similar one. I installed this on windows (cpu only). It seems the only option to install cpu only is with make python_cpu. I'm not sure the program installed correctly; after running the makefile (or gcc directly from command line):
gcc -O3 -fopenmp -fPIC -ftree-vectorize -march=native -shared fast_matched_filter/src/matched_filter.c -o fast_matched_filter/lib/matched_filter_CPU.so

nothing happens, although opening python and using import fast_matched_filter as fmf doesn't give any errors. However, when I try to call the function, as in the FMTuto notebook, I get the error

Cell In[12], line 2

      3                             moveout_array,
      4                             weight_array,
      5                             data['waveforms'],
      6                             matched_filter_step,
      7                             arch=architecture)
      8 t_end = give_time()
      9 print('{:.2f} s to run the matched filter search'.format(t_end-t_start))

AttributeError: module 'fast_matched_filter' has no attribute 'matched_filter'

clearly there is a function "matched_filter" in the fast_matched_filter.py though.
