Problem starting notebook and running cell
I've been trying on and off for months to start using Code with Jupyter plugin. Really hoping someone can help. I'm not completely sure what the problem is - though I know I can't run a cell. It seems like there is no connection to the Jupyter Kernel.
Environment data
VS Code version: 1.10.2 Jupyter Extension version: 1.0.0 OS and version: Sierra 10.12.3

Actual behavior
Notebook and or the Jupyter/iPython kernel doesn't start. When loading any .py and trying to run cell, '' as an error message is shown. I've tried to point Code to the appropriate kernel in setting, ex: "python.jupyter.defaultKernel": "Python 3". I've tried opening the file using root permissions and same problems.
Expected behavior
Based on what I've seen in the documentation, I'd expect the notebook to be loaded upon opening the file.
Steps to reproduce:
Open file -> try to run cell.
A suggestion, please could you try uninstalling this extension, and using the python extension. Ignore the 'obsolete message' that would be displayed. Please let me know if that works, I.e. whether it works on the python extension.
Thank you @DonJayamanne - much appreciated. Unfortunately that didn't work for me. After trying your suggestion I get an error stating:
Command: strk, Id: 0, Python Trace: Traceback (most recent call last):
I tried opening the python file directly from the command line using root privileges (which didn't work either) because the output from the error is:

@DonJayamanne if I check in the command line it give me:
anaconda Command line client (version 1.5.1)
I believe I started with anaconda 2, then at some point I downloaded and, I believe, am now using anaconda 3. Both versions remain in my file system though as you can see in the below images.
@DonJayamanne since you mentioned anaconda, I opened Anaconda Navigator and updated Jupyter notebook there. I had been running a Jupyter version 4.3.something, and now it's at 4.4.1. I then opened Visual Studio Code again via the command line (with my conda environment activated) and it now works!!!
I'm so excited to start using this as Jupyter notebook in the browser is painfully slow. If you'd like any other info from me I'm happy to keep plugging around. Otherwise, maybe if someone encounters a similar problem to me they should update Jupyter as I did.
A tangent here, but I want to thank you for making this. I also heard your interview on Talk Python to me. Awesome
I believe my issue is related. I use the option to "Start a new notebook" and receive the following prompt:
If I click "View Errors", I see this:
Notebook not selected/started

Same issue here.
On the Jupyter Notebook output I have this line:
[W 14:11:40.594 NotebookApp] 404 GET /%20/api/kernelspecs?1492517500564 (127.0.0.1) 21.00ms referer=None
Note the /%20/ at the begining of the URI.
Using this URI directly in the browser lead to the same error.
When removing /%20/, the browser show a JSON.
jupyter-core (4.3.0) notebook (5.0.0)
same issue for me
[W 08:26:13.274 NotebookApp] 404 GET /%20/api/kernelspecs?1500420373261 (127.0.0.1) 8.00ms referer=None

By default Jupyter disables listing available kernels. You guys need to modify two Jupyter config files to allow kernelspec listing.
Add following line to KernelGateway config file: c.JupyterWebsocketPersonality.list_kernels = True
I forgot which line to add to Jupyter Notebook config file, but you should be able to find it in Jupyter Notebook config options help page.
Good luck!
So issue 55 is by this ??

And I found there is no way to stop jupyter ?? I have to kill the progress.
Yes - you are running in to kernelspec issues.
If Jupyter is running in background, you can use "fg" to bring it to foreground and exit cleanly with two Ctrl-C strokes.
Unfortunately, I am in windows, no fg command ...
this
c.JupyterWebsocketPersonality.list_kernels = True
and https://github.com/DonJayamanne/vscodeJupyter/issues/55#issuecomment-336848152
both not work .
Following commands are for Linux, so adapt them for Windows as necessary.
# Generate config file for KernelGateway
jupyter kernelgateway --KernelGatewayApp.generate_config=True
# Generate config for Jupyter Notebook
jupyter notebook --generate-config --allow-root
# Append appropriate values to both config files
echo -e "c.JupyterWebsocketPersonality.list_kernels = True" >> ~/.jupyter/jupyter_kernel_gateway_config.py
echo -e "c.NotebookApp.allow_root = True" >> ~/.jupyter/jupyter_notebook_config.py
Thanks for the tip, prerequire in this link https://github.com/DonJayamanne/vscodejupyter/wiki is unaccessable.
I set c.JupyterWebsocketPersonality.list_kernels = True in ~/.jupyter/jupyter_notebook_config.py before.
That's wrong, need pip install jupyter_kernel_gateway .
Then got new error :
