Dipy - 属性错误：AttributeError：模块“numpy”没有属性“float”

Question

我正在使用 Dipy 库，当我尝试导入其中一个函数时，我收到此属性错误：

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:https://numpy.org/devdocs/release/1.20.0-notes.html#deprecationshttps://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

但是，我在回溯或代码库中的任何地方都没有看到 np.float 的任何使用。

我尝试使用 VS code 搜索代码库，但在任何地方都找不到 np.float 的单个使用，所以我不明白这个错误是如何发生的。

我正在使用

numpy 1.24.4

和

dipy 1.3.0

Answer 1

您需要更新您的

dipy

库以避免此错误。

dipy 1.3.0

是一个非常旧的版本，发布时间：2020年11月5日

---

试试这个：

pip install dipy==1.9.0

https://pypi.org/project/dipy/
