python - 导入错误 : cannot import name 'MNIST'

Question

我已经能够 pip 安装所有其他包，例如 bumpy、sklearn 等，但是 mnist 包抛出如下错误。我一直在尝试使用 sudo pip install 但它也说

applesys$ pip install mnist
Requirement already satisfied: mnist in            /Users/applesys/anaconda3/lib/python3.5/site-packages
Requirement already satisfied: numpy in /Users/applesys/anaconda3/lib/python3.5/site-packages (from mnist)
applesys$ sudo pip install mnist

Answer 1

请注意 python-mnist和 mnist是两个不同的包，它们都有一个名为 mnist 的模块。您需要的包是 python-mnist。所以这样做:

pip install python-mnist

可能需要卸载 mnist 包:

pip uninstall mnist

那么你的 import 语句应该可以工作了。
