ypeError: 'int' object has no attribute '__getitem__'
时间: 2023-09-25 18:12:22 浏览: 53
This error occurs when you try to use the indexing operator [] on an integer variable. The indexing operator is used to access elements of a sequence such as a list, tuple or string. However, integers do not support indexing, as they are not sequences.
For example, the following code will raise the TypeError:
```
x = 123
print(x[0])
```
To fix this error, ensure that you are using the indexing operator only on sequences such as lists, tuples or strings. If you need to access individual digits of an integer, you can convert it to a string first and then use indexing. For example:
```
x = 123
digits = str(x)
print(digits[0])
```

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>
