Anaconda jupyter 笔记本“连接失败”错误

Anaconda jupyter 笔记本“连接失败”错误

如何解决Anaconda jupyter 笔记本“连接失败”错误

我最近安装了 anaconda 并尝试运行 Jupyter Notebook。我使用的是 Windows 10。我打开了一个文件夹并运行了笔记本。每当我单击打开文件时,在将文件加载到新选项卡几秒钟后,我都会看到以下错误消息:

Error message

当我点击“确定”时,我也看到了:

我已经重新安装了 anaconda 三次以上,但这个问题仍然存在。我的互联网连接在这里不是问题,因为我可以在其他选项卡上运行 google。 以下是anaconda提示上的错误信息:\\

有人可以帮忙吗?我是一个公平的初学者,找不到答案。 提前致谢

解决方法

在重新安装 Anaconda 并在此处找到解决方案后,我遇到了同样的错误:https://github.com/jupyter/notebook/issues/4909

我激活了我有问题的环境并安装了以下内容:

  • conda install -c conda-forge pywin32
  • conda install -c anaconda jupyter_client
  • conda install -c conda-forge jupyter_core

像魅力一样工作!

github 上的 Jupyter 笔记本:隐藏文件路径

github 上的 Jupyter 笔记本:隐藏文件路径

如何解决github 上的 Jupyter 笔记本:隐藏文件路径?

我不认为这会是一个大问题,因为我认为许多数据科学家都有这个问题,但我没有通过谷歌搜索我的问题找到解决方案: 我有一个 Jupyter Notebook (JN),我为它创建了一个 Github 存储库。在 JN 中我定义了一个路径变量,如下所示:

data = ''folder/subfolder/datafile.csv''

如何避免显示此文件路径?有没有简单的方法? 也许我没有用正确的术语在谷歌上搜索?

非常感谢每一个帮助!

解决方法

这取决于您的操作系统。此 link 显示了如何在 Windows 上执行此操作。此 link 展示了如何在 Mac 上进行设置。

那么您的代码将如下所示:

import os
path = os.environ.get(''PATH'')

jupyter 笔记本 NameError:未定义名称“GraphSegmentation”

jupyter 笔记本 NameError:未定义名称“GraphSegmentation”

如何解决jupyter 笔记本 NameError:未定义名称“GraphSegmentation”

我正在做一个使用图形进行图像分割的项目,使用 Jupyter Notebook,我定义了一个类名 GraphSegmentation,并在另一个单元格中创建了一个 GraphSegmentation 类的对象,运行类定义单元格没有给出任何错误,但在下一个单元格,我收到名称错误。我该如何解决这个问题?

''''''
 graph_obj = GraphSegmentation()
 img = cv2.imread(''data/paris.png'',0)
 img = cv2.resize(img,None,fx=0.7,fy=0.7)
 smooth_img = graph_obj.gaussian_filter(img,3,0.8)
 print(''[info] : building graph'')
 ch1_G,ch1_E = graph_obj.image_to_grid_graph(smooth_img)
 print(''[info] : building graph complete'')
''''''

我收到以下错误 错误
