The flash attention is not required. If you use V100 or other GPU doesn't support flash attention, just change the FlashAttention2Available = RequirementCache("flash-attn>=2.0.0.post1") to FlashAttention2Available = False in the model.py file. It should be able to run.

python

import torch
from transformers import AutoModelForCausalLM

# load pretrain model
model = AutoModelForCausalLM.from_pretrained('qcw2333/YingLong_50m', trust_remote_code=True,torch_dtype=torch.bfloat16).cuda()

# prepare input
batch_size, lookback_length = 1, 2880
seqs = torch.randn(batch_size, lookback_length).bfloat16().cuda()

# generate forecast
prediction_length = 96
output = model.generate(seqs, future_token=prediction_length)

print(output.shape)

A notebook example is also provided here. The sample codes for long-term forecasting tasks and gift-eval tasks are provided at link.
