'str' object has no attribute 'shape'
时间: 2023-09-21 09:11:24 浏览: 70
This error occurs when you try to access the shape attribute of a string object in Python. The shape attribute is specific to numpy arrays, not strings.
For example, if you have a variable `my_string` that contains a string, and you try to access its shape attribute like this:
```
my_string.shape
```
You will get the error message: "'str' object has no attribute 'shape'".
To fix this error, you need to make sure that you are using the shape attribute with the correct type of object, such as a numpy array. If you are working with a string, you can use the `len()` function to get the length of the string instead.

AttributeError: 'str' object has no attribute 'shape'
这个错误通常发生在你试图在字符串对象上调用`shape`属性时。`shape`属性是用于查看Numpy数组或Tensor对象的形状的。字符串对象没有`shape`属性,因为它们是不可变的序列。
如果你希望查看字符串的长度,可以使用`len()`函数。例如:
```python
string = "Hello, World!"
length = len(string)
print(length) # 输出 13
```
请确保你在调用`shape`属性时是在正确的对象上调用,如果是字符串对象,应该使用`len()`函数而不是`shape`属性。
AttributeError: 'str' object has no attribute 'exists'
AttributeError: 'str' object has no attribute 'exists'错误通常是因为在代码中尝试访问一个字符串对象的不存在的属性。在这种情况下,根据提供的引用信息,该错误可能是由于在使用Pandas的DataFrame时调用了一个不存在的属性`exists`导致的。要解决这个问题,您需要检查代码中是否正确使用了Pandas的DataFrame,并确保没有调用不存在的属性。可以查看Pandas官方文档或相关的学习资源来了解DataFrame的正确用法和可用属性。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
