Importing pybgs crashes python runtime #207

Open jnissin opened 3 years ago

jnissin commented 3 years ago

Describe the bug

I have attempted to install pybgs both via pip:

pip install pybgs --force-reinstall --no-cache-dir

and from sources after cloning the repository via setup.py:

python setup.py build
python setup.py install

within a conda environment. In both cases I manage to install the library but when I attempt to import it the python runtime crashes:

$ python                                            
Python 3.8.12 | packaged by conda-forge | (default, Oct 12 2021, 21:50:56) 
[Clang 11.1.0 ] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pybgs
Fatal Python error: _PyInterpreterState_Get(): no current thread state
Python runtime state: unknown

[1]    79583 abort      python

To Reproduce

Install the library, either via pip or setup.py, and attempt to import it via import pybgs.

Expected behavior

The library is expected to import without crashing the python runtime.

System information

Desktop (please complete the following information):

Additional context

Building the library with CMake and running the example run_video.sh is successful. I have tried multiple different python versions, but the result is always the same.

Hello @jnissin , Sorry for my absence, I had to put the bgslibrary in standby for a long time. I will try to reproduce your issue in my local environment. I come back to you soon as possible, Thanks Andrews

xavibou commented 2 years ago

Hi, Is there any update on this? I installed pybgs on opencv 3.4.7 using pip and I am getting the same error at importing the library.

Thanks Xavi

Hello @jnissin @xavibou , sorry for my delayed feedback. I just released a new version of the BGSLibrary, now v3.1.0. I tested it on Windows, Mac and Linux, both compiling the C++ library on OpenCV 3.4.7, 3.4.16 and 4.6.0. I also tested its respective Python wrapper and GT user interface. Everything is working for me, could you please check in your side if this new version fix your issues? Thanks in advance, Andrews
