python - 模块“numpy”没有属性“dtype”

问题描述

导入 sklearn 数据集时，例如。

from sklearn.datasets import fetch_mldata
from sklearn.datasets import fetch_openml

我得到错误

Traceback (most recent call last):

    from sklearn.datasets import fetch_openml

AttributeError: module 'numpy' has no attribute 'dtype'

我不知道为什么我会得到这个

从 jupyter notebook 运行东西时我没有收到这个错误，这也很奇怪。对此问题的任何帮助将不胜感激

解决方案

我想通了。答案是我正在运行的文件名为 numbers.py。这搞砸了整个事情。如果您遇到此问题，请检查以确保目录中没有名为 numbers.py 的文件

简单的检查方法是将带有 import 语句的文件移动到不同的目录并尝试运行它。
