torchdata.datapipes is not working in Google Colab.

Even after installing the torchdata library, it raises an exception when datapipes function are imported.

I installed the dependencies

!pip install torchdata or !pip install --pre torchdata -f https://download.pytorch.org/whl/nightly/cpu/torch_nightly.html But when I write

import torchdata.datapipes as dp or

from torchdata.datapipes.iter import StreamReader,FileOpener,FileLister
 
from torchdata.dataloader2 import DataLoader2, MultiProcessingReadingService

it throws an error :

Exception                                 Traceback (most recent call last)
<ipython-input-15-01a976fbf894> in <cell line: 1>()

      3 from torchdata.dataloader2 import DataLoader2, MultiProcessingReadingService

    138         def class_function(cls, enable_df_api_tracing, source_dp, *args, **kwargs):

Exception: Unable to add DataPipe function name sharding_filter as it is already taken

What can be the possible causes and solutions?

The issue is automatically solved now. Library is working fine. Since datapipes are in beta development phase, my guess is that they might have updated some code.
