Install Scala in Colab.ipynb

install-scala-in-colab.ipynb

Hello Shadaj,
I hope you're well.
I would like to know if the installation procedure of the Scala kernel is still functional?
From Colab, there is no error when I run the Scala Kernel installation.
But, unfortunately, just running the "Hello World !" print does not work ...
Do you have any advice ?

Thank you.
Cheers,

Same as BilalKacel: the install seems to work, but the kernel does not load Scala. Tried to reload the page and restart the kernel but did not work for me.

I would strongly encourage this to be resolved

This was possible earlier, but indeed fails now

Hmm, this is surprising. I just used the same initialization code for a couple other notebooks in the past week and it seemed to work fine. Perhaps the notebook needs to be set to the Scala kernel like in https://gist.github.com/shadaj/29d77180aeefc41a749273026f7d1fd9 to work?

It seems to be working if you start from your notebook. But when I worked on it locally, I cannot select a new kernel anymore.

This is so disappointing. I can whip together and train a deep learning model in Python / keras in a matter of minutes, but I can't find anything comparable for Scala :-(

There is actually an important prerequisite to assure before you follow steps given by @shadaj: If you open a notebook with a text editor and compare the raw contents of a regular Notebook with that of a Shadaj's notebook, you'll see one crucial difference that you need to fix. So,

1. You need to open your Colab Notebook with a text editor (use any of the relevant Google Drive apps) and make sure the kernelspec.name key is set to work with Scala, like so:

{
  ⋮
  "kernelspec": {
    "display_name": "Scala",
    "name": "scala"
  }
  ⋮
}

(This is a necessary step for any non-pythonic kernel — be it Scala, Go or whatnot. Check my notebooks for examples: https://gist.github.com/kirisakow)

2. Save, close.

3. Now open normally with Google Colab engine and start working.

I edited the colab and set the kernel spec, saved and closed. When reopened the colab normally, I get "unrecognized runtime scala substituting default Python 3"

@Platinum-Dragon Just follow the steps in one of these colabs of mine:

• Run Scala in Google Colab with Almond
• Run Spark MLlib and Scala in Google Colab with Almond
