GStreamer: Failed to load plugin after 4.20.0 upgrade

After upgrading hailo-all to version 4.20.0, my gstreamer pipeline stopped working. I am getting the following error:

(gst-plugin-scanner:3055): GStreamer-WARNING **: 05:11:38.447: Failed to load plugin '/lib/aarch64-linux-gnu/gstreamer-1.0/libgsthailopython.so': libpython3.10.so.1.0: cannot open shared object file: No such file or directory
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
terminate called after throwing an instance of 'cv::Exception'
  what():  OpenCV(4.6.0) ./modules/imgproc/src/resize.cpp:4055: error: (-215:Assertion failed) inv_scale_x > 0 in function 'resize'

Aborted

gst-inspect-1.0 hailotools and gst-inspect-1.0 hailo returns expected outputs as outlined on this page.

The pipeline used to work before the upgrade. Please let me know if you have any ideas as to how to solve this issue. Thanks in advance!

Hey @eren

I’m pleased to inform you that we’ve released Hailo Package version 4.20 with all previous bugs resolved. You can now update to the latest version, and everything should work smoothly.

Thank you for your patience while we addressed these issues.

Best regards,
Omria

Hey @omria,

That indeed appears to be solved. However, the issue I outlined in my other thread has been persistent–I had applied the update with the hopes of solving that issue but with no luck. It is also possible that the issue stems from an error in my pipeline, but I wasn’t able to pinpoint any issues regarding that either as I tried numerous changes. Any ideas on that one?
