AttributeError: 'float' object has no attribute 'sqrt'

根据引用，出现了TypeError: loop of ufunc does not support argument 0 of type float which has no callable sqrt method AttributeError: ‘float’ object has no attribute ‘sqrt’的错误。这个错误可能是因为在代码中使用了一个float类型的对象，但是float类型没有sqrt方法。为了[解决](https://geek.csdn.net/educolumn/03368addd5d267af1b4c6df01bb4af26?spm=1055.2569.3001.10083)这个问题，可以使用numpy模块的sqrt[函数](https://geek.csdn.net/educolumn/ba94496e6cfa8630df5d047358ad9719?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083)，将float类型的对象转换为numpy数组，然后再进行平方根运算。具体的[解决](https://geek.csdn.net/educolumn/03368addd5d267af1b4c6df01bb4af26?spm=1055.2569.3001.10083)方法是使用np.sqrt[函数](https://geek.csdn.net/educolumn/ba94496e6cfa8630df5d047358ad9719?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083)，将envelope_data ** 2和hx ** 2两个对象转换为numpy数组后再进行平方根运算，即hy = np.sqrt(np.array(envelope_data) ** 2 + np.array(hx) ** 2) [1。 另外，根据引用，numpy无法处理sympy的Float类型。在[调试](https://geek.csdn.net/edu/300981ef51993cfd737d329c71ba77f9?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083)过程中，可以看到Wapproxlist的类型是sympy.core.numbers.Float。为了<span class="em">1</span><span class="em">2</span><span class="em">3</span> #### 引用[.reference_title] - *1* [[Python报错] AttributeError: ‘float‘ object has no attribute ‘sqrt](https://blog.csdn.net/m0_
