Hi All,
I am not sure what I did but the kernel is dead.
How can I recover or fix it.

Hi @kim13
Can you please navigate to Administration->Code envs and check that DEV code env exists? It might be the case the notebook was saved while using this code env but it was deleted from the instance.
If it's not there, you can either recreate it or switch to another code env in the notebook.
Hi Sergeyd, @sergeyd
DEV is still available. Please see attached pic.
I am not sure if its related to https://community.dataiku.com/t5/Setup-Configuration/pkg-resources-DistributionNotFound-The-certifi-... ?
Hi @kim13
Can you please SSH into DSS server and run the next command:
find /home/dataiku/dss/code-envs/python/ -ls > python_code_env_listing.txt
and send me this resulted file?
Hi @sergeyd ,
Unable to create SSH connection. Please help. I install dataiku on virtual box running on linux.
Please see pic.
Hi @kim13
Sorry, but I asked to SSH into the DSS server and not create an SSH connection in DSS UI. If you are using the virtual box image provided by DSS, the instructions are shown in the console:
If you are using another VM (installed from the scratch), then you can either open console directly or SSH into it via putty (Windows) or with Terminal (Mac, Ubuntu).
Has this notebook worked before or you hit this issue right after the DSS installation?
