Error Processing operation (notebook name)

[sleepo-chin]

I do jupyter-hub connect with elyra and elyra connect to enterprise gateway

• elyra 1.1.0 or anything else (i'm not remember it)
• not use kubeflow

Before I change the kernel of notebook. That notebook is no kernel. If I opened notebook and select my kernel on enterprise gateway such as tensorflow kernel.

so I run pipeline agian. This is a error for me:

Traceback (most recent call last):
  File "/opt/conda/lib/python3.7/site-packages/elyra/pipeline/processor_local.py", line 151, in process
    subprocess.run(argv, cwd=file_dir, env=envs, check=True)
  File "/opt/conda/lib/python3.7/subprocess.py", line 512, in run
    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['papermill', '/home/jovyan/work/Untitled.ipynb', '/home/jovyan/work/Untitled.ipynb', '--cwd', '/home/jovyan/work']' returned non-zero exit status 1.

The above exception was the direct cause of the following exception:

The above exception was the direct cause of the following exception:

In the logs of jupyter lab said me that no kernel name tensorflow, but I can use a kernel tensorflow for run notebook.

I want to know how to fix that for kernels on enterprise gateway for run pipeline on locally Thank for your answer.

While we look into this issue, an immediate workaround would be to change the kernel to a local Python 3 kernel.

@sleepo-chin Based on our investigation and some discussion around the team, this seems to be a sort of deep issue on how we run pipelines locally, but the good news is that we have a possible solution that we are working on and will keep you updated via this issue. Anyway, thanks for trying Elyra and we will let you know when a pull request is available.

@sleepo-chin This is now on Elyra 1.3.x release, please let us know if you see any other issues related to this.
