Question

由于某种原因，我什至无法运行此基本行。它应该只接受它，但它甚至不会这样做。每次我打开Jupyter Notebook时，都会发生类似的情况。当然，实际上没有任何方法可以永久修复它。我没有太多可以尝试的方法，但是与Jupyter混为一谈也使我的其他IDE搞砸了。

from __future__ import print_function, division

%matplotlib inline

import numpy as np

import nsfg
import first

Answer 1

好像您使用的是matplotlib的旧版本。例如，version 0.91.2在transforms.py中没有Bbox类，但是大多数较新的版本都有。

要确认这一点，请打开引用的文件/Users/hedyeherfani/opt/anaconda3/lib/python3.7/site-packages/matplotlib/transforms.py，然后检查class Bbox(BboxBase)或其他内容相似（需要定义一个称为Bbox的符号）
将import matplotlib; matplotlib.__version__评估为Python解释器，以确定您的matplotlib版本。
使用pip install matplotlib==<newversion> --upgrade

Jupyter Notebook甚至无法正常工作
