我使用python 3内核在jupyter笔记本上运行了卷积神经网络教程中的以下代码，并得到了ModuleNotFoundError：没有名为“ autoreload”的模块；
import numpy as np
import h5py
import matplotlib.pyplot as plt
%matplotlib inline
plt.rcParams['figure.figsize'] = (5.0, 4.0) # set default size of plots
plt.rcParams['image.interpolation'] = 'nearest'
plt.rcParams['image.cmap'] = 'gray'
%load_ext autoreload
%autoreload 2
np.random.seed(1)
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-1-3d0ea63c7843> in <module>()
