potential memory leak

[Slyne]

Hi~

I use valgrind to test the below line:

import kaldifeat

The log is here: https://1drv.ms/t/s!AhtoTbISXXlSgSLtqDWjo8RP_ouA?e=Sn1cd0

Log summary:

==20510== LEAK SUMMARY:
==20510==    definitely lost: 0 bytes in 0 blocks
==20510==    indirectly lost: 0 bytes in 0 blocks

Reproduce

valgrind --leak-check=full --show-reachable=yes --trace-children=yes --track-origins=yes --trace-children=yes --log-file='log.txt' python3 test.py

test.py

import kaldifeat

Could you help check if these are potential issues? Thanks!

Please have a look at pytorch/pytorch#39522
It is a known issue when using valgrind with PyTorch.

Do you mind checking this issue: triton-inference-server/server#3777 (comment) ?

There's an invalid pointer issue related to kaldifeat + pybind.

Please see the comment at triton-inference-server/server#3777 (comment)

I would suggest you to file an issue at https://github.com/pytorch/pytorch/issues

You can replace import kaldifeat with import torch when posting the issue.

@Slyne Hi, I was wondering if you figure it out or posting the issue in pytorch.
