**Problem:** In the beginner tutorial part 3: advanced link level simulations, when executing the command "UT_ARRAY.show()" the following error occurs: "Type Error: float() argument must be a string or a...
When trying the Part 4: Toward Learned Receivers example at the step Training the Neural Receiver I get an error about TensorShape to a Tensor: (None, None) while i did...
Hello, The following question / remark concerns only the TDL channel models as they are the ones I have been using. Yet this may also apply to others channel models,...
Dear Sionna community, I've been playing around with this tutorial: https://nvlabs.github.io/sionna/examples/Sionna_Ray_Tracing_Introduction.html for quite a while. The thing is that after computing in a `for` loop: `y = channel([x, h_freq, no])`,...
When running k-best = 4 and antenna configuration 128 x 128 BPSK i get the following error. TypeError: Expected tensor [1. 2. 4. 4. 4. 4. 4. 4. 4. 4....
I have installed Sionna on a AMD Ryzen 5 5600G CPU running on Windows 11 and am facing de problem shown on the screenshots below when running the RT Tutorial...
Trying Sionna-RT for my research, I noticed strange behavior with wedges/edges and, particularly, a method for swapping edge extremities to orient identical edges in the same way. The problem was,...
Simple example to reproduce this: https://gist.github.com/japm48/41bc963efec39e506c17e419c3d1e13f Basically, the demapper outputs NaN values when the SNR is too low, this can be seen that by reducing `ebno_db` this issue goes away....
## Description Closes issue #326. This simply adds the machine epsilon to `no` before computing the exponents. A min threshold could be used instead, but with this method differentiability is...
Every time I try to get a coverage map, I get the following error: UnknownError: {{function_node __wrapped__FloorMod_device_/job:localhost/replica:0/task:0/device:GPU:0}} JIT compilation failed. [Op:FloorMod] I am on Windows Native, using TF 2.10.1, Sionna...
