problems using local jupyter with google colab

I am using jupyter notebook with google colab, on Ubuntu 20.04LTS with Python 3.8.5.

Problems I face are:

  1. connection drops suddenly. I mean, to say, colab never executes a cell, instead it just keeps waiting. By waiting, I mean, the cell I run always looks like this enter image description here and never turns into this: enter image description here. But, colab does say that I am connected to an instance: enter image description here.
  2. everytime I write something and wait for autocomplete to show suggestions, I receive a TypeError that says, there was unexpected keyword argument 'column'. Here's the complete error message right from the launch of jupyter:

Details about computer:
This is actually an AWS EC2 instance(c5a.4xlarge) I have port mapped to my local laptop, to be able to use jupyter notebook on colab. Both my laptop and EC2 instance are running Ubuntu 20.04LTS.

Package versions:
I have installed jupyter on 16-Jan-2021 by doing pip3 install jupyter. So, I believe I got the latest version available and here are the package versions along with some dependencies of jupyter:

ipykernel==5.4.3
ipython==7.19.0
ipython-genutils==0.2.0
ipywidgets==7.6.3
jedi==0.18.0
Jinja2==2.11.2
jsonschema==3.2.0
jupyter==1.0.0
jupyter-client==6.1.11
jupyter-console==6.2.0
jupyter-core==4.7.0
jupyter-http-over-ws==0.0.8
jupyterlab-pygments==0.1.2
jupyterlab-widgets==1.0.0
kiwisolver==1.3.1
MarkupSafe==1.1.1
matplotlib==3.3.3

mpmath==1.1.0
nbclient==0.5.1
nbconvert==6.0.7
nbformat==5.1.2
nest-asyncio==1.4.3
notebook==6.2.0

How do I fix these issues?

Solution

  • The second issue is caused by your jedi version. You can fix it with:

    pip install --upgrade 'jedi<0.18.0'
