notebook server - access to files on notebook side, upload menu in dashboard

[den-run-ai]

How can I access the files on notebook client side for use as data in the notebook computations, if the notebook server is located on remote machine?

Right now I can only access the files on the notebook server side.

Is the only option to copy the files to remote server?

client and server side do not have common storage access

Yes, all your code is running on the machine where the notebook server is. If they don't share a filesystem, then you will need to either copy the files to where the code runs, or run the server where the files are (technically you need to run the kernels there, but the easiest way to do that is to run the server there).

But it is possible to send files over sockets for built-in support in ipynb

If you're running the notebook server on the remote machine, then the only communication with your local machine is the websockets your browser opens. And the browser doesn't have filesystem access.

Looks like this maybe the solution:

ipython/traitlets#12

How can I modify that widget example not to display the file in notebook but to save it on remote ipython server?

[takluyver]

It is transferring it to the kernel. Check file_widget.value after you've selected a file.

[den-run-ai]

I was able to transfer text files, but binary did not go through correctly. Is there any way to transfer "raw" binary data using that widget?

Now I think it is better to include the file upload option right in the dashboard

[den-run-ai]

I found that Upload button on https://try.jupyter.org/, how do I get the same button on my notebook server installation?

[minrk]

The upload button should be the same on local IPython as on try.jupyter. What version of IPython are you using?

[den-run-ai]

'3.0.0'

[den-run-ai]

Ok, I got the upload button on latest version.
