Problem of installing fCWT on linux

[neil20030304]

I installed fCWT on the linux server using the command 'pip install fCWT' but get the error 'ImportError: libfftw3f.so.3: cannot open shared object file: No such file or directory' when trying to import the lib in python script. How to resolve the issue?

I am getting the same error when installing fcwt in Colab. Steps to reproduce are:

Install the library in Colab:

!pip install fcwt

Import the library

import numpy as np
import matplotlib.pyplot as plt
import fcwt

This returns

[/usr/local/lib/python3.11/dist-packages/fcwt/__init__.py](https://localhost:8080/#) in <module>
----> 1 from .fcwt import Morlet, Scales, FCWT, FCWT_LINSCALES, FCWT_LOGSCALES, FCWT_LINFREQS
      2 from .boilerplate import cwt, plot
      3 

[/usr/local/lib/python3.11/dist-packages/fcwt/fcwt.py](https://localhost:8080/#) in <module>
     11 # Import the low-level C/C++ module
     12 if __package__ or "." in __name__:
---> 13     from . import _fcwt
     14 else:
     15     import _fcwt

ImportError: libfftw3f.so.3: cannot open shared object file: No such file or directory

Any idea how to move forward?
