scipy: if _is_safe_size(n):

[jeremyNG-lab]

Hi,
This is my code with Accz and Time are array of float:

cwt = ContinuousWaveletTransform(wavelet= morse.Morse())
CPEF=cwt.transform(data =Accz, fs =1000, timestamps =Time, freq_limits =[0,300])

And the answer:

File ".......\lib\site-packages\scipy\fftpack\basic.py", line 87, in fft
if _is_safe_size(n):

TypeError: c2c() missing 1 required keyword-only argument: 'plan'

Hello,

What version of scipy are you using, and do you have a full traceback of the issue when you run the code?

[jeremyNG-lab]

I use scipy 1.3.0 but I had lot of problem with scipy like No module named....
What version you use?

[jchutrue]

I've been using pyfftw for the FFT backend. For scipy, if you have the full traceback of all your issues, I can take a look. Right now I'm not sure what the specific problems are.

[jeremyNG-lab]

So at the bigging I use the last scipy (1.6.0)

from . import morlet
File "......\anaconda3\lib\site-packages\ghost\wave\morlet.py", line 5, in
from scipy.misc import logsumexp
ImportError: cannot import name 'logsumexp' from 'scipy.misc' (C:\Users\jerem\anaconda3\lib\site-packages\scipy\misc_init.py)_

I changed in the file scipy.misc by scipy.special

_from .fourier import clean_scipy_cache
File ".....\anaconda3\lib\site-packages\ghost\sigtools\fourier.py", line 5, in
import scipy.fftpack._fftpack as sff
ModuleNotFoundError: No module named 'scipy.fftpack.fftpack'

I changed by from scipy.fftpack import fft as sff

And I saw your last message that you use pyfftw so i installed this package and it works.
I think that pyfftw must be installed for a good work .

[jchutrue]

The issue with scipy is that they removed some functions in later versions. I'll get around to fixing that today so that you can still use scipy as the fft backend if you want. But in general I do prefer to use pyfftw.

[ckemere]

I think the two pull requests I proposed will fix these issues. But you should update the home page example to also import pyfftw so that people do this by default.

[jchutrue]

@jeremyNG-lab The errors should be gone now--let us know how it looks on your system

[jeremyNG-lab]

Without the FFT backend I have the same issu:

File "....\anaconda3\lib\site-packages\ghost\sigtools\fourier.py", line 11, in clean_scipy_cache
sff.destroy_zfft_cache()
AttributeError: 'function' object has no attribute 'destroy_zfft_cache'

[ckemere]

The master branch has been changed. Make sure you pip install it again?

[jeremyNG-lab]

I redownload and reinstall the package. But with scipy it didn't work, the same issue.

[jchutrue]

This might have something to do with scipy's legacy code. Try it now?

EDIT: i.e. run pip install again
