Unable to successfully start kernel - "No Module named 'prompt_toolkit.formatted_text'" #18

Closed jiata closed 5 years ago

jiata commented 6 years ago

Error looks like this:

getimage 1

getimage 2

Environment:

Ubuntu DSVM (i also tried on an ubuntu 18.04lts VM)
conda environment created using the environment.yml provided
nb_conda_kernels enabled (i believe this enabled by default on the dsvm)

Other notes:

switching to other kernels (or rather, other conda environments) seem to work

jiata commented 6 years ago

Reinstalled ipykernel 4.8.0 and it worked

pip uninstall ipykernel
pip install ipykernel==4.8.0

jiata commented 6 years ago

Just tried explicit declaration of ipykernel==4.8.0 in environment.yml file and re-created environment, but that didn't work.

Hi @jiata, I'm looking at this right now. The problem is that azure-cli requires an older version of prompt_toolkit, and that causes the kernel failure. I'm working on a workaround.

Fixed with PR #29
