how to get notifications on execution?

[EHV-PB]

Using Putty, i have a series of bash documents that run nbclient for me, but i want to get a notification in the notebook execution fails. I haven't figure out how to rig that.

!/bin/bash
export PATH=/home/ubuntu/anaconda3/bin:$PATH
jupyter nbconvert --to notebook --execute /home/ubuntu/MyNotebooks/Notebook.ipynb

add some line of code to send email if execution fails, times out, etc.

This isn't the right place to ask this question. For one, you're using nbconvert and this is the repo for nbclient. Second, this isn't really an issue with nbconvert but a question about a specific use case.

That said. You likely just want to check the return code of the jupyter command. Something like this (untested code):

#!/bin/bash
export PATH=/home/ubuntu/anaconda3/bin:$PATH
NOTEBOOK_PATH="/home/ubuntu/MyNotebooks/Notebook.ipynb"
LOGFILE="/home/ubuntu/MyNotebooks/notebook_error.log"
EMAIL="your_email@example.com"

# Execute the notebook, redirecting stderr to the log file
jupyter nbconvert --to notebook --execute "$NOTEBOOK_PATH" >/dev/null 2>"$LOGFILE"

# Check the exit code of the jupyter command
if [ $? -ne 0 ]; then
  # If it failed, send the log file as the email body
  SUBJECT="[FAIL] Jupyter Notebook: $NOTEBOOK_PATH"
  cat "$LOGFILE" | mail -s "$SUBJECT" "$EMAIL"
