Failure to start Kernel due to Modules not installed

Python kernels can fail to start if some modules such as pytprocess ipykernel, pyzmq, etc are not installed.

Recommended solution

• Please consider installing the missing modules.
• If they have already been installed, its possible it hasn't been installed correct, hence try the reinstall option as follows:
  • python -m pip install <xyz> -U --force-reinstall
  • conda install --name <environment name> --update-deps --force-reinstall (if using Conda environments)
