Error Computing coverage map with RIS

[Athmajan]

Referring to the tutorial : Sionna_Ray_Tracing_RIS.ipynb

I am learning to use RIS with Sionna. When generating coverage maps with RIS included, I am getting this error
InvalidArgumentError: cannot compute ConcatV2 as input #1(zero-based) was expected to be a float tensor but is a int32 tensor [Op:ConcatV2] name: concat

cm_ris = scene.coverage_map(num_samples=2e6, #increase for better resolution max_depth=5, los=True, reflection=True, diffraction=True, ris=True, cm_cell_size=[4,4], cm_orientation=[0,0,0], cm_center=[0,0,1.5], cm_size=[200,200])

Executed the Colab Notebook without any changes to the given file.

Hi @Athmajan,

Thanks for reporting this issue. I can reproduce it. Will be fixed.

Hi @jhoydis
I am using Sionna for my research. Just wanted to know what's the ETA for this issue fix.
Thank you.
