How to specify kernel while executing a Jupyter notebook using Papermill's Python client?


How to specify kernel while executing a Jupyter notebook using Papermill's Python client?

this one helps. I am running a jupyter notebook script using Papermill's python client. While running, I want to specify the kernel. However, the script ran within the same kernel as my active python shell(through which I made the API call to papermill in order to run the notebook's script). , Not sure if this is too late now, but you can check this:
code :
papermill {input_path} {output_path} -k {kernel_name}

Does that help A very simple example would be (paste the code below in a notebook cell):
code :
%%javascript

// Function that accepts a string of code
var create_and_execute_cell_below = function (code){
    var nb = Jupyter.notebook

    // create cell below this one
    nb.insert_cell_below()

    // select cell below (the one we have created)
    var cell = nb.select_next().get_selected_cell()

    // set text in the cell
    cell.set_text(code)

    // execute cell
    cell.execute()
}

// run the function created above with code 'k = 1'
// and it will create a new cell, filled with 'k = 1'
// and it will execute that cell.
// if you run this cell using [ctrl] + [enter] only one cell
// will be created.
// if you run this cell using [Shift] + [enter] two cells
// will be created, the one of the [Shift] + [enter] command
// and the one of the function created above with the code.
create_and_execute_cell_below('k = 1')

With these it helps Are you using pip3 install jupyter?
a more robust solution would be to isolate your environments with something like pipenv.
code :
pip install pipenv

pipenv install --three
pipenv install jupyter
pipenv shell
jupyter notebook
Can I run a jupyter notebook with an R kernel from a jupyter notebook with a python kernel?

this one helps. Your error is not due to the kernel selected. Your command %run is made to run python only, but it has to be a script, not a notebook. You can check in details the ipython magic commands
For your use case I would suggest to install both python and R kernel in jupyter. Then you can use the magic cell command %%R to select to run R kernel for a cell inside the python notebook. Source :this great article on jupyter - tip 19
code :
!R path/to/script.r

I wish this helpful for you The kernel may be fully ready before the nbextension subscribes to kernel_ready event. In that case we can directly use kernel:
code :
if (Jupyter.notebook.kernel) {
    // ... 
} else {
  Jupyter.notebook.events.one('kernel_ready.Kernel', (e) => {
    // ...
  });
}
