3 leaked semaphore objects to clean up at shutdown_MONAILabel

Operating system:Windows 10 Pro
Slicer version: 5.12

Hello everyone,

I am using MONAI to train an algorithm. However, as I submit the labels and press the train button this message appeared today a couple of times on the log file (see attached).

The main message is ‘‘There appear 3 leaked semaphore objects to cleanup at shutdown’’

What is the cause of this error and did anyone encounter in the past such an issue?

Thank you in advance for your replay
