Add CTC decoder builds for more Python versions

[lissyx]

We hard-coded the action call with one version

it would be nice to:

• use a matrix for all versions we can
• add new train-test-model jobs using a matrix as well to ensure test coverage

@Ayushsunny This might be easier, if you are still willing to learn GitHub Actions at the same time

Thank you so much as you want me to learn. It's so nice of you Sir @lissyx .
and yes I want to learn, So what I have to do first is to understand this specific topic to fix this issue

So what I have to do first to understand this specific topic to fix this issue

Read this code, get yourself into https://docs.github.com/en/actions/guides :)

[lissyx]

@Ayushsunny Have you been able to get a grasp of what needs to be done ?

[lissyx]

@Ayushsunny Ping?

[Ayushsunny]

I'm really sorry Sir @lissyx
I was studying for my University Exam.
Now I'm free and from tomorrow I'll start working on it.

Thanks, I don't want to pressure you, it's fine if you can't take it, but we just need to know :)

So Sir, as per my understanding I think this should be the code which I have to add. @lissyx ?

jobs:
  build:
    runs-on: macos-10.15
    strategy:
      matrix:
        python-version: [ '2.x', '3.x', 'pypy-2.7', 'pypy-3.6', 'pypy-3.7' ]
    name: Python ${{ matrix.python-version }} sample
    steps:
      - uses: actions/checkout@v2
      - name: Setup python
        uses: actions/setup-python@v2
        with:
          python-version: ${{ matrix.python-version }}
          architecture: x64
      - run: python my_script.py `

@Ayushsunny Sorry looks like my reply got lost ; that's the good basis, you'll have to build on top of that.

Which reply Sir? @lissyx
and, may make a PR for this? or I need to improve the last code which I've sent .

One I thought I had sent

and, may make a PR for this? or I need to improve the last code which I've sent .

What you shared is not what we need, but it's on the right path.

We need a job like the one I shared earlier, but on more versions of python.
