TypeError: empty() received an invalid combination of arguments - got (tuple, dtype=NoneType, device=NoneType), but expected one of: * (tuple of ints size, *, tuple of names names, torch.memory_format memory_format, torch.dtype dtype, torch.layout layout, torch.device device, bool pin_memory, bool requires_grad) * (tuple of ints size, *, torch.memory_format memory_format, Tensor out, torch.dtype dtype, torch.layout layout, torch.device device, bool pin_memory, bool requires_grad)

这个错误提示表明你在调用 PyTorch 的 `empty()` 函数时传入了错误的参数组合。正确的参数组合有两种：

1. `empty(size, *, names=None, memory_format=torch.contiguous_format, dtype=None, layout=torch.strided, device=None, requires_grad=False)`
2. `empty(size, *, memory_format=torch.contiguous_format, out=None, dtype=None, layout=torch.strided, device=None, pin_memory=False, requires_grad=False)`

其中，第一个参数是张量的大小，可以是整数，也可以是元组。第二个参数是一个命名参数，可以为 `names`、`memory_format`、`out`、`dtype`、`layout`、`device`、`pin_memory` 和 `requires_grad` 中的任意一个或多个。具体使用哪些参数取决于你的需求。例如，如果你需要创建一个空的张量，可以像下面这样调用 `empty()` 函数：

import torch

# 创建一个大小为 (3, 4) 的空张量
x = torch.empty((3, 4))

如果你还有其他的需求，可以根据需要传入其他参数。

TypeError: empty() received an invalid combination of arguments - got (tuple, dtype=NoneType, device=NoneType), but expected one of:

这个错误是由于调用了torch.empty()函数时传入了无效的参数组合导致的。torch.empty()函数期望的参数组合包括：size (int, tuple 或者 torch.Size)，dtype (torch.dtype, 可选) 和 device (torch.device, 可选)。

请检查你传入的参数是否符合这些要求，并确保参数的类型正确。如果你能提供更多的代码和错误信息，我可以帮助你更详细地解决这个问题。

TypeError: sum() received an invalid combination of arguments - got (out=NoneType, axis=NoneType, ), but expected one of:

To fix the "TypeError: sum() received an invalid combination of arguments" error, you need to provide valid arguments to the sum() function. The sum() function in Python can be used to sum up the elements of an iterable, such as a list or tuple.

The error message suggests that you are using invalid arguments for the sum() function. The sum() function expects either a single iterable argument or two arguments (iterable and start). Here are some examples of correct usages:

1. Summing up elements of a list:

   numbers = [1, 2, 3, 4, 5]
   total = sum(numbers)

2. Summing up elements of a tuple:

   numbers = (1, 2, 3, 4, 5)
   total = sum(numbers)

3. Summing up elements of a list starting from a specific value:

   numbers = [1, 2, 3, 4, 5]
   total = sum(numbers, 10)  # Start summing from 10

Make sure you are passing a valid iterable as the first argument to the sum() function. If you provide any additional arguments, ensure they are valid as well.
