如何修复 AttributeError: module 'scipy' has no attribute 'constants'

问题：

尝试运行 Python 项目时，你看到类似这样的错误消息

scipy_attribute_error.txt

AttributeError: module 'scipy' has no attribute 'constants'

AttributeError: module 'scipy' has no attribute 'constants'

即使你已经导入了 scipy：

repro_import_scipy.py

import scipy

import scipy

你需要显式导入 scipy.constants

fix_imports.py

import scipy.constants

import scipy.constants

我通常建议同时导入 scipy 和 scipy.constants，以防你在代码的其他地方使用 scipy 本身：

recommended_imports.py

import scipy
import scipy.constants

import scipy
import scipy.constants
