Fails to call numpy fft on android

[llamawright]

Versions

• Python: 3.7.1
• OS: Android 8.1.0
• Buildozer: 0.39

Description

I am trying to use the numpy fft for real input in an android app. But when I use it I get SIGSEGV everytime. The simple program below illustrates the problem. Thanks.

import numpy as np
import platform

print("platform.python_version() == ", platform.python_version())
print("np.version == ", np.version )

data = np.array([0.1, 0.2, 0.5, 0.5, 0.6, 0.1, 0.9, 0.8])
print(" Now crazy starts: ")
result = np.fft.rfft(data)

print(" Result: ", result, " Finished!")

#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*

Thanks for the log, but I'm not sure what's wrong here, and I've used numpy.fft.fft before without issues. I'll try to test it again.

[llamawright]

Thanks for the response. Have you been able to repeat the error? I have tried this on two different devices with exactly the same results. Any suggestions/info would be gratefully received, as I am totally stuck on this issue.

[llamawright]

This issue has been resolved with the latest Numpy release (7 Sept 2019).

[jgavris]

@llamawright could you share your spec file that resolved the issue for you?
