这是因为在BART模型的推理过程中遇到了CUDA的设备端断言。要解决此问题，可以尝试使用PyTorch的torch.autograd.set_detect_anomaly(True)来发现计算图中的异常，将其包装在with torch.autograd.detect_anomaly():块中进行训练，以便在发现错误时进行调试。

示例代码：

import torch
from transformers import BartForConditionalGeneration, BartTokenizer

tokenizer = BartTokenizer.from_pretrained('facebook/bart-large')
model = BartForConditionalGeneration.from_pretrained('facebook/bart-large')

# 打开异常检测
torch.autograd.set_detect_anomaly(True)

# 将代码包装在with语句中
with torch.autograd.detect_anomaly():
    input_text = "summarize: it is a beautiful day outside, with the sun shining and the birds singing."
    input_ids = tokenizer.encode(input_text, return_tensors='pt')
    outputs = model.generate(input_ids)
