Potential memory leak in PaddleOCR?

[nikos-livathinos]

I have noticed some weird memory usage when evaluating the performance of PaddleOCR:

• When PaddleOCR processes new images of a sequence, there is a constant increase in memory usage of the process.
• The time profile of the memory usage has sudden steps to higher memory levels.
• If the system sets an upper bound in the memory consumption, the paddle process is eventually killed. It won't give allocated memory back, ever.
• This behaviour can be observed both with the C++ and the Python interface.

Eventually it is impossible to keep running a PaddleOCR process as a service because the system runs out of memory and the process is killed.

Can you provide insights on this memory usage pattern? Do you have any remedy?

The following issue describes the tests in detail: #7823

Thanks for your feedback.

Next, I will focus on analyzing the problem of memory leaks.
