nn.CTCLoss doesnt exists!

Hi all,
Until today torch.nn.CTCLoss still not exists? where can I see the latest information about CTC update?
This code, still now not work:

!pip install torch_nightly -f https://download.pytorch.org/whl/nightly/cu92/torch_nightly.html    
import torch
from torch import nn 
ctc_loss = nn.CTCLoss()

---> 15 ctc_loss       = nn.CTCLoss()
     16 print('Done!!!!!!')

AttributeError: module 'torch.nn' has no attribute 'CTCLoss'

Why? how I can get the CTC work?

Are you sure that you actually installed the nightly? Could you print the version number?
