I'm experienced with Jupyter Notebook and am coming over to Google Colaboratory. I noticed that Colab does not have an option to restart the runtime and clear all the outputs; is that correct?
In Jupyter Notebook, the option is under Kernel --> Restart & Clear Output.
However, in Google Colab, there is no such option under the Runtime menu:
When I click on Restart Runtime..., it only shows the following:
Any help would be appreciated.
To clear outputs, go to 'EDIT' and 'clear all outputs'.
If you want to reset all packages, data files etc. installed, you have got to the runtime as you mentioned.
Hopefully, it helps. :)

I've been trying to build a CordApp and I downloaded the template from GitHub. The code that I've written is available on the following link:
https://github.com/shanmukhipriya99/taskcordapp
When I'm trying to run gradlew.bat deployNodes in the cmd terminal, this is what I got:
[gradlew.bat deployNodes]
Then when I run build\nodes\runnodes in the cmd terminal, this is what I got:
[build\nodes\runnodes]
Then I have three other terminal windows opening-up, they load the Corda part, show some red text that says something about the developer mode and all the node terminals get closed automatically before I'm able to read the entire text.
Can someone please help me in figuring out where I'm wrong!?
Thanks in advance!
It looks like you have had successfully started the nodes all in one terminal. I am not entirely sure, if this is the only issue, but I have seen this issue before. This is caused by lack of permission of the Terminal.
I have seen it happened for both Windows and Unix/Macos users. To resolve it you might need to grant the permission to Terminal manually.
If it still does not work out, I would actually suggest the alternative quick fix that Ashutosh mentioned in comment. Open a new tab and go to the root folder of each nodecd /build/nodes/XXX, and start the node manually via java -jar corda.jar
I am trying to run a R notebook on Microsoft's Azure notebooks cloud service.
When I am trying to run all cells, it displays a Loading required package: ggplot2 in the last cell and then the Kernel systematically crashes. I get:
The kernel appears to have died. It will restart automatically.
But the Kernel does not restart automatically.
How can I get a log describing the encountered issue? Is there a way to activate a debugger?
When you're running Jupyter usually you'll see messages about kernel issues in standard I/O of the console that you launch. In Azure Notebooks this gets redirected to a file at ~/.nb.log. You can open a new terminal by clicking on the Jupyter icon, and then doing New->Terminal, and doing cat ~/.nb.log. You could also start a new Python notebook for this purpose and do "!cat ~/.nb.log" - but unfortunately you can't just do that from an R notebook, they don't support the "magic" ! commands.
Usually that gives you a good starting point. If that doesn't help much you could try invoking R directly from the terminal and trying the repro steps there and see if that's more useful.
I tried to autocomplete the path in jupyter notebook. After I press 'tab', it shows much more than folder or file. I think those are build-in function of python. Is there any way to show only path and files while autocomplete the path?
Thanks!
This is a known issue, not critical and developers have just so much time. It should not be too hard to fix, IPython is open source, you are welcome ton contribute !
I am having massive trouble with using vpython in jupyter notbooks. I'm creating small animations with vpython. After a couple of minutes when I try to run a cell, it will either not show any output or will yield a error message "object could not be called".
The only fix I found for this is to restart or change the kernel. Most times it works then for the next few minutes until it stops again. This is really annoying and prevents real progress.
pictrue of error message with example code
all used objects have been imported in another cell before this one.
I am running vpython 7.3.2 and anaconda navigator 1.6.10 on a mac with High Sierra. As a browser I use Chrome.
Thank u for every hint to fix this permanently in advance!
Cheers,

Try asking your question on the vpython forum and perhaps provide a sample notebook on github where with instructions on how to reproduce the problem.
https://groups.google.com/forum/?fromgroups&hl=en#!forum/vpython-users
Here is a link to demo vpython notebooks running in the cloud using binder service.
https://mybinder.org/v2/gh/BruceSherwood/vpython-jupyter/master?filepath=Demos
If you provide a notebook on github that demonstrates the problem then it should be reproduceable when running on mybinder.

I load extensions to IPython notebook (powered by Jupyter) with the following command in ~\.ipython\profile_default\static\custom\custom.js.
IPython.load_extensions("calico-spell-check", "calico-document-tools");
The extensions are correctly loaded in the first notebook I open. But they are typically disabled in the following notebooks I open. Then when I close, reopen, etc. the notebooks they are loaded (seldom) or not (often) without any specific message in the console.
Is it a problem of compatibility with Jupyter or rather a bad configuration of mine?
You are hitting a race condition. Most of the instruction on how to activate extension in custom.js are wrong/too old when they tell you to directly copy past code in custom.js. Please follow official docs, use requirejs, and register the extension following the information in official docs.
