Hi,
regarding your first question, let's diagnose:
1. Are you sure your Python environment is loaded correctly, such that
datalab --version
prints v2.20.0 ?
2. If yes, you can try to move your local $HOME/.datalab/dl.conf file, and then try again (it will create a new dl.conf file, and you will have to log in again one time):
mv $HOME/.datalab/dl.conf $HOME/.datalab/dl.conf.bak
datalab login # enter your username and password
Then try again you original command(s). Please let us know if you still see an SSL certificate error.
Regarding your question about LS: while we did just now update several tables in DR8, it is recommended to use DR9, as it supersedes prior data releases). Regarding you seeing only zeros in the two columns, can you please post your exact query, so that we can try to reproduce the result?
Thanks,
Robert
