- Expected integer literal for index but got a variable or non-integer. ModuleList/Sequential indexing is only supported with integer literals. For example, 'i = 4; self.layers[i](x)' will fail because i is not a literal. Enumeration is supported, e.g. 'for index, v in enumerate(self): out = v(inp)':
- Attribute 1 is not of annotated type
- Unsupported value kind: Tensor
- reversed(Tensor 0) -> Tensor 0:
- tuple slice indices must be integer constants:
- reversed(Tensor 0) -> Tensor 0:
- builtin cannot be used as a value:
- Cannot input a tensor of dimension other than 0 as a scalar argument
- OSError: could not get source code
- 'Tensor (inferred)' object has no attribute or method 'bool'.:
- Dict 值为多种类型时： Any 或 Union

Expected a value of type ‘Tensor’ for argument ‘self’ but instead found type ‘Optional[Tensor]’.
数据类型为可None类型，但算子不接受None，需要去掉类型的可None。
xs:Optional[torch.Tensor] = None
assert xs is not None
x = xs / 10
Expected integer literal for index but got a variable or non-integer. ModuleList/Sequential indexing is only supported with integer literals. For example, ‘i = 4; self.layersi’ will fail because i is not a literal. Enumeration is supported, e.g. ‘for index, v in enumerate(self): out = v(inp)’:
Attribute 1 is not of annotated type
通常是由 ModuleList 或者 ModuleDict 的遍历或取元素引起的。
3 种解法：
第一种是推荐做法: 直接使用遍历
m = nn.ModuleList()
m.append()
for index, v in enumerate(m):out = v(inp)
第二种是无法直接遍历，必须用下标取值。但是自定义的module，可以把继承torch.nn.Module
