python memory leak when using CPU execution provider with multiple threads

[JustinNober]

When I use onnxruntime-cpu to use multithreading on python, I found the problem of memory growth; in my continuous loop test reasoning, I found that the free memory in the cpu is getting smaller and smaller.

The same problem occurs in the threading library。

The red box is the memory I monitor，This gets smaller and smaller and doesn't release.

Have you tried forcing garbage collection periodically and seeing what effect that has?

[JustinNober]

Tried but nothing works.

Maybe there really has a memory leak, but the way you watch memory usage is wrong. Do not look at the "free" column". The last column is what really matters.
