Hello, I am trying to run the tutorial https://colab.research.google.com/github/Nixtla/neuralforecast/blob/main/nbs/examples/IntermittentData.ipynb on my local windows machine. I have installed all the necessary packages on a clean python virtual env using 
pip install neuralforecast statsforecast s3fs fastparquet
cmd. I am getting the below error:
Copy code
from neuralforecast.losses.pytorch import DistributionLoss
ImportError: cannot import name 'DistributionLoss' from 'neuralforecast.losses.pytorch' (E:\MT\code\env\lib\site-packages\neuralforecast\losses\pytorch.py)
Can someone please help. python version is 
3.10.9
c

It is possible the DistributionLoss is not yet in PyPi, we will update the version in the following days. In the meantime, you can install it directly from the main branch with 
pip install git+<https://github.com/Nixtla/neuralforecast.git@main>
