mitsuba-blender: Installation: Blender crash after installing with pip

Hi, blender is crashing after I installed mitsuba via the “install dependencies using pip” button. The error I get in the command line is:

munmap_chunk(): invalid pointer
[1]    6518 IOT instruction (core dumped)  ./blender

, crash log At any further launch of blender I get the following error:

Writing: /tmp/blender.crash.txt
[1]    6723 segmentation fault (core dumped)  ./blender

, crash log

To Reproduce Steps to reproduce the behavior:

Download blender 3.3 and run it
Download latest release of mitsuba-blender (9d9a4cb) and install it
Install mitsuba using the button “install dependencies using pip”
Blender crashes

Resources If applicable, add screenshots or other files (Blender projects, Mitsuba scenes) to help explain or demonstrate your problem.

Environment (please complete the following information):

OS: Linux (Fedora 36)
Blender Version: 3.3.0, 3.2.2, 2.93.10
Add-on Version: latest (9d9a4cb)

Thanks for your help.

@arpit15 the crash comes from the fact that the dynamic loading of the plugin DLLs also use the RTLD_DEEPBIND flag internally. I have been working on a work-around for this issue today, hopefully will be able to push this in the coming days (then we will also need to wait for the next release).

Temporaly if you are compiling Mitsuba locally, you can edit the plugin.cpp file and remove the usage of the RTLD_DEEPING flag. This is only really necessary when working with PyTorch and Mitsuba in the same Python script.
