Input shape mismatch occured for features in module EncDecDiarLabelModel
Audio was stereo, my mistake
**Describe the bug**

Encountering this error when running the speaker diarization training tutorial notebook on my own data:
Input shape mismatch occured for features in module EncDecDiarLabelModel : 
Input shape expected = (batch, time) | 
Input shape found : torch.Size([2, 208000, 2])

**Steps/Code to reproduce bug**

I have run the data preparation scripts 'pathfiles_to_diarize_manifest.py' and 'create_msdd_train_dataset.py' on my own data.
My own data consists of a single .wav and .rttm file for each of 'train' and 'valid'.
The training rttm has 9 speakers.
The pairwise rttm files have been created successfully.
I am then loading the 'msdd_5scl_15_05_50Povl_256x3x32x2.yaml' config file and setting it up as follows:
