Windows Subsystem for Linux error-- cannot communicate with local orca server process even though server process seems to be running

Hello all,

I am trying to write an image to .svg format using a jupyterlab setup on Windows Subsystem for Linux (WSL). After installing gtk library, installing Xming, configuring env variable DISPLAY=:0, and disabling chrome sandbox, I am still running into issues. Right now, I’m getting the following error output in my python terminal:

For some reason plotly.py was unable to communicate with the
local orca server process, even though the server process seems to be running.

Please review the process and connection information below:

orca status
-----------
    state: running
    executable: /usr/bin/xvfb-run --auto-servernum --server-args -screen 0 640x480x24 +extension RANDR +extension GLX /usr/bin/orca
    version: 1.2.1
    port: 60427
    pid: 29156
    command: ['/usr/bin/xvfb-run', '--auto-servernum', '--server-args', '-screen 0 640x480x24 +extension RANDR +extension GLX', '/usr/bin/orca', 'serve', '-p', '60427', '--plotly', '/home/tyler/.local/share/virtualenvs/thesis-WAlznkOk/lib/python3.7/site-packages/plotly/package_data/plotly.min.js', '--graph-only', '--mathjax', 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js']

Any pieces of advice? Other than examining the server connection, which i’m not entirely sure what is meant by that, I’m wondering if there are any other WSL-compatibility shortcuts i might be able to take. It would be great if this library could include additional documentation/support for WSL

Just tried here and can confirm your procedure works @raulf2012!

Some aditional missing shared libraries had to be installed: sudo apt-get install libgtk2.0-0 sudo apt-get install libnss3-dev

Thanks for sharing!

Wow I can’t believe it, I got it to work

My steps:

1. Install conda/anaconda (instructions available elsewhere)
2. Install nodejs (npm) through conda

• conda install -c conda-forge nodejs

1. Install orca through npm via instructions on orca’s README

• npm install -g electron@1.8.4 orca

1. Finally, I needed to install a library because of the missing shared libgconf-2.so.4 library

• sudo apt-get install libgconf-2-4

After these steps, attempting to perform a fig.write_image("figure.pdf") worked properly!

@schlich I’m a bit puzzled by your initial comments on this thread:

After installing gtk library, installing Xming, configuring env variable DISPLAY=:0, and disabling chrome sandbox, I am still running into issues

I didn’t really have to mess around with any of this, I do already have Xming setup properly but the gtk library and chrome sandbox bits are unfamiliar to me

If anybody else can try to confirm the procedure I outlined above and let everybody know if it works that would be great
