最近,我在我的 Jupyter 笔记本上安装了第二个版本的 Python,这样我就可以在需要时使用 Python 2 或 3。但是,在安装 Python 3 之后,我在以前的 python2 笔记本上遇到了 matplotlib、scipy 和 numpy 的问题。
输入:
%pylab inline
import time
import datetime
import glob
import os
from os import system
import platform
import scipy.ndimage as snd
import numpy as np
from matplotlib.pyplot import *
给我:

我从中得到的是 Python 2 在查看导入时不再指向正确的目录。我该如何设置正确目录的路径?
最佳答案
我完全卸载了所有内容,然后重新安装,路径已更正。
