Description

📚 The doc issue

On debian 13 after installing torchcodec and ffmpeg (via apt-get install) importing torchcodec fails with "Could not load library: ... libtorchcodec_custom_ops7.so" (ops not core!). I straced it and what's actually missing is "apt-get install python3-dev" which install libpython3.13 along with it

Research direction

Start by reproducing the import failure on Debian 13 after installing torchcodec and ffmpeg, then trace the loader path involved in importing torchcodec. The fix is done when a missing libpython dependency is identified accurately instead of being reported as libtorchcodec_custom_ops7.so, with a regression check for the corrected error.
