Kernel DoA #78

Closed ryan-williams closed 7 years ago

ryan-williams commented 8 years ago

I just installed 5.0.13 via npm, ran ijs, tried to create a Node-kernel notebook, and the kernel repeatedly dies at startup.

Server output:

Let me know if anything jumps out, thanks!

This issue should be fixed in the latest release (IJavascript v5.0.14). Please, feel free to reopen if this issue is still present after updating.

periscuelo commented 8 years ago

For me this error persist in version 5.0.14

Could you post which the versions you're using?

$ ijs --version $ npm version $ jupyter --version

Also could you post the output of running ijs --ijs-debug?

When you run ijs --ijs-debug, I'd like to see the log after opening a new JS notebook in the frontend. I'm hoping ijs will report what's causing the kernel to die.

UPDATE: Before there was a 404 Error GET Widgets. I ran the command jupyter nbextension enable --py --sys-prefix widgetsnbextension and the output has changed but still doesn't work.

n-riesco commented 8 years ago

@periscuelo I can't reproduce this issue on a linux machine with Jupyter 4.2.0. I'm going to need your help to debug this issue further.

The first thing to try is to rule out this is a problem with the installation of ZMQ. Assuming you installed IJavascript globally, could you uninstall it and install it again. Like this:

$ npm uninstall -g ijavascript
$ npm install -g ijavascript

The above would fix issues caused by an old installation of ZMQ.

If the issue still persists, then we still need to make sure the installation of ZMQ works. If the installation of ZMQ is functional, the following should print out ZMQ is OK:

$ npm i zmq
$ node -e "require('zmq'); console.log('ZMQ is OK');"

If this fails, please, post of the output of running npm version.

Let's assume ZMQ works but IJavascript doesn't. Since Jupyter doesn't show any log messages from IJavascript, let's try to launch the IJavascript kernel manually:

$ jupyter kernelspec list --json
{
  "kernelspecs": {
    "javascript": {
      "resource_dir": "/home/user/.local/share/jupyter/kernels/javascript", 
      "spec": {
        "language": "javascript", 
        "display_name": "Javascript (Node.js)", 
        "env": {}, 
        "argv": [
          "/usr/bin/nodejs", 
          "/home/user/lib/node_modules/ijavascript/lib/kernel.js", 
          "{connection_file}", 
          "--protocol=5.0"
        ]
      }
  }
}

argv tells you how to start an IJavascript:

$ /usr/bin/nodejs /home/user/lib/node_modules/ijavascript/lib/kernel.js {connection_file} --protocol=5.0

where {connection_file} is a path to a connection file. Here's a sample connection file:

{
  "stdin_port": 46041, 
  "ip": "127.0.0.1", 
  "control_port": 54231, 
  "hb_port": 35904, 
  "signature_scheme": "hmac-sha256", 
  "key": "1db6a454-03fe-444a-98ad-93dd9d29d083", 
  "kernel_name": "javascript", 
  "shell_port": 51318, 
  "transport": "tcp", 
  "iopub_port": 40244
}
$ /usr/bin/nodejs /home/user/lib/node_modules/ijavascript/lib/kernel.js /path/to/sample/connection_file.json --protocol=5.0

In this end, this post turned out to be longer than I meant. Please, don't hesitate to ask if any of the instructions need clarification.

periscuelo commented 8 years ago

Sure, no problem.

If this fails, please, post of the output of running npm version.

The console.log didn't print nothing.

Eureca! It Worked! I will explain how works on windows 10.

  1. In https://github.com/nodejs/node-gyp#installation explain how you can install node-gyp in windows using npm install --global --production windows-build-tools
  2. In prompt, change to folder C:\Users\yourUser\.windows-build-tools\python27
  3. $ npm config set msvs_version 2015
  4. $ npm install node-gyp
  5. $ npm install zmq
  6. $ npm install -g ijavascript
  7. $ jupyter notebook

P.S. If Python 2.7 was not installed by step 1, got to C:\Users\yourUser\.windows-build-tools\ and execute the python installer file.

When i ran the notebook and it worked!

The problem is: you have to install node-gyp and zmq by npm from inside python27 folder. That's because my default python is 3.5 and not 2.7. In my case, Python 2.7 exists only inside python27 folder.

I uninstalled node-gyp, zmq and ijavascript and made the steps 2 - 7 and be happy =)

Thank you very much for the support.

The latest release, IJavascrip@5.0.15, uses prebuilt ZMQ bindings and Python 2.7 isn't required.
