[Query] OpenCV error on running obfuscated script on RaspPi 3B

[e0lithic]

Hi,

I have a library which I am trying to obfuscate on the RaspPi 3B. Here are the commands being run to obfuscate:

pyarmor obfuscate --exact __init__.py  --plugin ~/.pyarmor/plugins/check_ntp_time
pyarmor obfuscate --restrict 4 --recursive --exclude __init__.py . --with-license licenses/rcode-001/license.lic 

The obfuscation happens sucessfully. However, the following exception occurs while using a certain function of the library.

Python 3.7.3 (default, Dec 20 2019, 18:57:59) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

However, if I run the library without obfuscation it runs perfectly fine. Please let me know what I am missing.

Thanks

This is a known issue for some armv7 platforms, I have not found how to fix it. One solution is to specify basic feature library when obfuscating the scripts, for example,

pyarmor obfuscate --platform linux.armv7.0 foo.py
