Which version of Sionna fully support RIS and coverage_map with it?

[shamsul-haq-shuvo]

There is a known bug in Sionna version 0.19.1 where attempting to run a coverage_map with ris=True enabled crash the notebook with a ConcatV2 tensor error.

As I am working with RIS I would like to know which sionna version support RIS fully and doesn't crash with coverage_map.
I would also like to know the compatible mitsuba, drJit and tensorflow version as well.

And information on when RIS will be available on Sionna 1.x?
Thank you in advance.

PS: I am using Ubuntu 24.04 and running on RTX 5060.

Hello @shamsul-haq-shuvo,

According to #735, the ConcatV2 error was fixed in Sionna 0.19.2.

The compatible versions of Mitsuba and Tensorflow are listed in the requirements.txt of that version:

sionna/requirements.txt

Lines 1 to 6 in 3ec2138

	tensorflow >=2.13.0, <2.16.0
	numpy
	scipy >=1.6.0
	matplotlib >= 3.5.3
	importlib_resources
	mitsuba >= 3.2.0, <3.6.0

Unfortunately, we currently do not have plans to bring RIS support to Sionna 1.x.
