AttributeError when running tutorial part 3

[lkh9908]

I am running tutorial part 3 provided in https://nvlabs.github.io/sionna/examples/Sionna_tutorial_part3.html

And I got AttributeError: Exception encountered when calling layer 'lmmse_equalizer' (type LMMSEEqualizer).

module 'sionna' has no attribute 'config'

at

x_hat, no_eff = lmmse_equ([y, h_hat, err_var, no])

How should I fix it? Or is it caused by a patch update?

Hi,

I am not able to reproduce this error.

Which version of Sionna are you using (print(sn.__version__))?

Could you run print(dir(sn)) in a new cell in the notebook and copy & paste the output?

[lkh9908]

Thank you for the fase response: print(sn.version):

0.15.0

print(dir(sn)):

['ALPHA_MAX', 'Config', 'DIELECTRIC_PERMITTIVITY_VACUUM', 'H', 'PI', 'SPEED_OF_LIGHT', 'builtins', 'cached', 'doc', 'file', 'loader', 'name', 'package', 'path', 'spec', 'version', 'channel', 'config', 'fec', 'mapping', 'mimo', 'nr', 'ofdm', 'rt', 'signal', 'utils']

And the error occurs at: x_hat, no_eff = lmmse_equ([y, h_hat, err_var, no])

As you can see, the module sionna (imported as sn) has the property config. Not sure what is going on. Have you tried to restart the kernel? Could you provide a minimum code example that leads to the error?

[lkh9908]

I will try restarting the kernel, I have not changed anything from the original example online.

Thank you!
