这个错误表明DataLoader在尝试使用默认的collate_fn函数来合并一批数据时,发现这一批数据中的元素不是PyTorch张量(tensors)、NumPy数组(numpy arrays)或数字(numbers)。这通常是因为数据预处理或数据加载阶段出现了问题。 2. 检查数据加载部分 确保您的Dataset类中的__getitem__方法返回的是正确的数据类型。这个方法应该...
检查自定义collate函数:如果你使用了自定义的collate函数,仔细检查函数的实现,确保它可以正确处理多种数据类型,并返回正确的批次数据格式。 正确进行数据预处理:在将数据送入模型之前,使用torch.utils.data.DataLoader的collate_fn参数来指定一个函数,该函数负责将小批量数据整理成批次数据。这样可以避免手动编写collate函数...

Can I use a COLLATE clause in a temp table definition? Can I use aggregate function within CASE? Can I use if statement in a table valued function? Can I use LEN or DATALENGTH in a WHERE clause? Can I use OUTER JOIN on 2 columns at the same time? Can row_number() work in UNION...

Changing it to float tensor can potentially downcast users' data. You should be able to provide a custom collate_fn to DataLoader to accomplish your requirement. ejguan closed this as completed Dec 13, 2021 Sign up for free to join this conversation on GitHub. Already have an account? Sign...
