can't use longvit

[abebe9849]

I create new conda env and then

pip install -r requirements.txt
pip install git+https://github.com/shumingma/fairseq.git@moe
pip install -v -U git+https://github.com/facebookresearch/[email protected]#egg=xformers

installed above.

however,I cant try using longvit

#https://github.com/microsoft/torchscale/blob/main/examples/longvit/longvit.py
#L241 add these code
model = LongViT(img_size=1024)
import torch
out = model(torch.randn((2,3,102,4,1024)))
print(out)

what should i do next?
