🐛 Bug
The kernel_name argument of papermill.execute seems to have no effect. The executing notebook uses the Jupyter kernel specified in the original notebook's metatdata. Using papermill v2.6.0. Or at least the display_name in the metadata is unchanged, this is what jupyter hub uses to display the name of the kernal being used.
Something along the lines of this function should fix this:
importnbformatasnbfdefchange_notebook_kernel(input_path,output_path,kernel):""" Change a Jupyter Notebook's kernel. Parameters ---------- input_path: str Path to the input notebook. output_path: str Path to the output notebook. kernel: str Name of the kernel_name to change to. """notebook=nbf.read(input_path,as_version=4)notebook['metadata']['kernelspec']['name']=kernelnotebook['metadata']['kernelspec']['display_name']=kernelnbf.write(notebook,output_path)
