Problems running czt after install: No module named czt

[maso27]

When I attempt to run the example "zoom-dft.ipynb" (copy-pasted into a .py file), I receive this error:

Traceback (most recent call last):
  File "zoom-dft.py" line 6, in <module>
    import czt
ModuleNotFoundError: No module named 'czt'

I'm testing on Ubuntu 20.04 LTS Installed czt with <pip3 install czt> Ran the program with <python3 zoom-dft.py>

I have also tried downloading the zip from this github page and installing with <python3 setup.py install --user> I receive the same error there.

I can make it work by copying czt.py into the same directory as the example, but I don't think the installer is working right.

I think this is because I was using packages=find_packages() in setup.py when czt isn't actually a package (i.e., not a directory with an __init__.py file). I've changed this line to py_modules=['czt'] so it should work now. I've also updated the version on PyPI.

Let me know if that works for you.

I'm testing this on a fresh live boot of Ubuntu, so packages are pretty fresh from the start.

So when I type <pip3 install czt>, I get: ModuleNotFoundError: No module named 'numpy'

After installing numpy, when I type <pip3 install czt>, I get: ModuleNotFoundError: No module named 'scipy'

However, after installing scipy, everything works!

I think it's now a dependency issue, but a step in the right direction.

Thanks for the quick action!

I have Scipy and Numpy listed under install_requires in setup.py, so I'm not sure why you're getting ModuleNotFoundError. I've added a requirements.txt file, which might help.

Thanks for your feedback!
