How to Enable Spell Checker in Google Colab (Colab Operates on Linux Os)

How can I enable spell checker in google colab (colab operates on linux OS)?

I'm not aware of any way of doing so directly within Google Colaboratory, however a usable workaround might be to install a third party spell-checking browser plug-in such as Grammarly or another similar plug-in that works with your preferred browser, I know this probably wasn't the answer you where looking for, but I'm not aware of any better solutions, I truly apologize! But I hope this was at least somewhat helpful!Sorry I can't be of more help!

Is there a general way to run Web Applications on Google Colab?

You can plan to start a server on a port, e.g. port=8000. Find the URL to use this way.

from google.colab.output import eval_js
print(eval_js("google.colab.kernel.proxyPort(8000)"))
# https://z4spb7cvssd-496ff2e9c6d22116-8000-colab.googleusercontent.com/

Then, start the server, e.g.

!python -m http.server 8000

And click the first link above (instead of localhost or 127.0.0.1), it will open in a new tab.

Display in cell

You can display the result in an iframe in the output part. I made it into an easy function to call.

from IPython.display import Javascript

def show_port(port, height=400):
  display(Javascript("""
  (async ()=>{
    fm = document.createElement('iframe')
    fm.src = await google.colab.kernel.proxyPort(%s)
    fm.width = '95%%'
    fm.height = '%d'
    fm.frameBorder = 0
    document.body.append(fm)
  })();
  """ % (port, height) ))

Now you can start a webapp (here it is http.server) in a background. And display the result as an iframe below it.

get_ipython().system_raw('python3 -m http.server 8888 &') 
show_port(8888)

To stop the server, you can call ps and kill the process.

x11 forwarding through Google Colab

tl;dr

1. Open 6000/tcp port on your router and firewall
2. Install VcXsrv
3. Run "XLaunch" with "Disable access control"
4. Run "!apt-get install x11-apps && export DISPLAY=YOUR_IP_ADDRESS:0.0 && eyes" on Colab

Check

1. Google Colab does not keep environment variables across code cells. So you should set DISPLAY variable each them.

2. Xming may disallow remote connection as a default setting. At least, VcXsrv do that. Try to disable access control. This is an insecure option.

3. Router and firewall must open 6000+n/tcp port. The n is display number counting from 0. (e.g. HOSTNAME:0.0 → n=0)
