ypeError: 'int' object has no attribute '__getitem__'
时间: 2023-09-18 10:07:15 浏览: 41
This error occurs when you try to access an item in an integer object using the square bracket notation, which is used for indexing lists, tuples, and other sequence types. Since integers are not sequence types, they do not support indexing.
For example, the following code will raise this error:
```
x = 5
print(x[0])
```
To fix this error, make sure that you are using the correct data type for your intended operation. If you need to access individual elements of a collection, use a list, tuple, or other appropriate sequence type. If you need to perform arithmetic or other mathematical operations on numbers, use integers or floats as appropriate.

ROS 启动demo。launch时出现TypeError: 'int' object has no attribute '__getitem__'
这个错误通常是由于在 ROS Launch 文件中使用了错误的语法导致的。具体来说,可能是在 Launch 文件中使用了 Python List 或者 Tuple 的索引语法,但是索引的对象实际上是一个整数类型的变量。这样会导致 Python 报出 `'int' object has no attribute '__getitem__'` 的错误。
要解决这个问题,你需要仔细检查 Launch 文件中使用的语法,确保所有的索引操作都是针对 List 或者 Tuple 类型的变量进行的。如果你无法找到具体的问题所在,可以将你的 Launch 文件贴出来,让我帮你检查一下。
'int' object has no attribute 'get'
这个错误说明在一个'int'对象上调用了一个不存在的'get'属性。
根据提供的引用,这个错误可能与给定代码中的某些问题相关。例如,在第二个引用中,错误可能是由于使用了np.nan而不是None导致的。
此外,第三个引用中给出了一个使用reduce函数的示例,该函数要求输入和输出具有相同类型。根据这个示例,错误可能是由于在reduce函数中使用了一个'int'对象而不是一个可迭代的对象导致的。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
