问题 I want to set some parameters as defined here(https://github.com/nteract/papermill#python-version-support). The catch is, I want to be able to do this via UI. I have a JHub installed on my cluster and while opening it, I want certain parameters to be set by default. Also, when I pass the parameters via papermill(the above script gets saved somewhere and then I will run it via papermill), I want the latter to override the former. I tried looking into several topics in pure JuPyter notebooks

问题 I`m using jupyter notebook on a shared environment with multiple user, while magic is powerful it's actually a double edge sword, an irresponsible user can use commands to run linux command directly for example !ls /opt this command will allow you to list down all /opt directory !pip install <some package> will allow user to install package directly from jupyter notebook and many other magic command that has potential to change system How do I turn off several / all magic commands on jupyter

问题 I am using JuPyter hub on k8s. It has a persistent volume claim. I want to have my users use a variable run_id = "sample" every time they use jupyter notebook. Doing so requires making a file aviral.py in the path /home/jovyan/.ipython/profile_default/startup with the content run_id = "sample" . I have to do this manually and would want this to be done as soon as the new user's pod is created for the first time i.e. the file gets written there itself. Is there any way to automate this?

问题 I am trying to plot some data from a camera dynamically using drawnow. However, the dynamic plotting (using matplotlib and drawnow) doesn't seem to be working on jupyter notebook. It's currently working in Pycharm. My code: import matplotlib.pyplot as plt import numpy as np from drawnow import * x = np.random.randn(10, 2) def function_to_draw_figure(): plt.plot(i, j, 'r.') plt.ion() figure() for i, j in x: drawnow(function_to_draw_figure) plt.xlim(-1, 1) plt.ylim(-1, 1) plt.pause(0.5) I would

问题 I accidentally deleted a jupyter notebook file on my Google Cloud instance. I wonder if there's anyway to restore/recover the file? 回答1: Thanks to this link, I found the solution. Files deleted in the browser should probably be in a Trash folder.

If yes, then simply using the mv command you can move your
