我在jupyter notebook上使用python 3内核运行卷积神经网络教程中的以下代码,结果出现了“ModuleNotFoundError: No module named 'autoreload'(找不到名为 'autoreload' 的模块)”的错误提示;
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: No module named 'autoreload'
我在这个问题上找不到任何解决方案。我应该如何修复这个错误?
import autoreload
。你的Python路径出了问题。在你的路径中应该有一个autoreload.py
,通常在类似于.../lib/python3.6/site-packages/IPython/extensions
的地方。在sys.path
中寻找类似的东西。 - Marmadukeimport autoreload
加载模块吗?扩展文件夹是否在 sys.path 中? - Marmaduke
