Python 3.8.0 import numpy fails

[eusoubrasileiro]

I followed the instructions in here for numpy and scipy installation.

My Python, default for pkg. Python 3.8.0 (default, Dec 5 2019, 10:53:43) [Clang 8.0.7 (https://android.googlesource.com/toolchain/clang b55f2d4ebfd35bf6 on linux

I am on Android 5.1.1 and uname- m aarch64

Unfortunatelly I get after import numpy ModuleNotFoundError: No module named 'numpy'

Weirdly I found that it installed in site-packages numpy for python 3.7.5. But there is no python 3.7.5 installed.

if I install using pip install numpy I get the following when I try import numpy

If I install the python 3.7.5 from termux-pod using dpkg -i I get the error bellow and I cant even install the static version.

I manage to install from source using the 1.18 version. Unfortunatelly, it also went bad.

Is it possible for me to build a wokring numpy for aarch64 for python 3.8.0 or early versions? Could give me some advice or guidance?

Thank you very much

the current version uses https://its-pointless.github.io/files/24 you need https://its-pointless.github.io/files/21 this should be in the file $PREFIX/etc/apt/sources.list.d/pointless.list

[eusoubrasileiro]

Thank you very much for the answer it would certainly work.

Unfortunately, since I am turning my old phone in a NVR system I installed a custom room (LineageOS 15.1 - Android 8.1.0) and pip install numpy worked in there.

Thank you again!

High, sorry to bother you, I currently think I have the opposite issue: I have 21 (for some reason!) and I should have 24, because I am on Android 11 and my python is 3.10. Can I simply change "21" to "24" in the pointless.list file, update, and expect everything to work fine?

Thanks in advance
