ttributeError: 'tuple' object has no attribute 'length'
时间: 2023-11-07 16:04:59 浏览: 17
您遇到的错误是因为元组对象没有 "length" 属性。元组是一个不可变序列,它们的长度可以通过内置函数 "len()" 来获取。您应该将 "length" 替换为 "len()",并将其应用于元组对象。
正确的代码示例:
```
my_tuple = (1, 2, 3)
tuple_length = len(my_tuple)
print(tuple_length)
```

ttributeError: 'tuple' object has no attribute 'view'
这个错误通常出现在使用PyTorch编写LSTM时,因为LSTM的输出是一个元组(tuple),而元组没有view属性。解决方案是将元组转换为张量(tensor),然后再使用view方法。例如,如果你的LSTM输出为output和hidden,你可以使用以下代码将它们转换为张量并使用view方法:
```
output, hidden = lstm(input)
output = output.view(batch_size, seq_length, num_directions * hidden_size)
```
其中,batch_size是批量大小,seq_length是序列长度,num_directions是LSTM的方向数(单向或双向),hidden_size是隐藏层大小。这样,你就可以使用view方法对输出进行操作了。
AttributeError: 'tuple' object has no attribute 'size'
This error occurs when you are trying to access the 'size' attribute of a tuple object, but tuples do not have a 'size' attribute.
For example:
```
my_tuple = (1, 2, 3)
print(my_tuple.size)
```
In this code, we are trying to print the size of the tuple 'my_tuple', but since tuples do not have a 'size' attribute, we get the AttributeError.
To fix this error, you can use the built-in function 'len()' to get the length of a tuple:
```
my_tuple = (1, 2, 3)
print(len(my_tuple))
```
This will output the correct length of the tuple, which is 3 in this case.
