我是 Python 的新手,正在尝试在我的 Mac 上的 Jupyter Lab 中运行他人的代码。它需要一个名为 pymc3
的包,我在终端中(conda install pymc3
)和从 Jupyter Lab 中遵循这些说明安装了该包:
import sys
!conda install --yes --prefix {sys.prefix} pymc3
我对theano
包采用同样的方法进行了操作。当我运行import pymc3
时,仍然会出现以下错误:

我可以告诉你,这与文件路径和环境有关,一个遇到类似问题的人通过“设置单独的conda环境”进行了解决,但我不知道如何实现。非常感谢您的任何建议。
