DSS install on osx (python environment)
How do I change the default python environment when installing DSS on mac from the default 2.7 to 3.7?
I want this piece of the installer script:
[Install] [+] Initializing Python environment
[+] Initializing Python environment using platform default
[Install] + Using default base Python for this platform : /usr/bin/python2.7
to point to /usr/bin/python3 (which is my python3.7 installation...)

Hi @Antonius
I assume you are using DSS9 because Python3.7 is supported starting only from DSS9. Also, if you have a previous DSS version and now upgraded to DSS9, before switching the python version please make sure that the code you have used for the built-in code env is compatible with Python3.7.
To switch the python version, you will need to rebuild the built-in env. For this please follow the next article:
The upgrade command should be:
dataiku-dss-VERSION/installer.sh -d DATA_DIR -u -P python3.7

Thanks! it did help the article regarding rebuild the environment, though tweaked for the mac mini I have.

Hi,
I picked the info for Linux and searched for the same process in Mac; I opened the Terminal and ran:
export DKUPYTHONBIN=/usr/local/bin/python3.7
I did a test to see if I did it right with:
echo $DKUPYTHONBIN
I did the above as to test if I could run DSS on my Mac mini M1 and it seems that it helped (plus other things I did, see post).

I was able to install python 3.6 on Mac OS 10.15.7 and then run the re-install python 3.6 in DSS.
I used homebrew to install pyenv to install python 3.6 with the commands
# install pyenv
brew install pyenv pyenv-virtualenv pyenv-virtualenvwrapper
# install prerequesits for pyenv compilation
brew install openssl readline sqlite3 xz zlib
# install latest python 3.6 as of April 2021
pyenv install 3.6.13
# make python 3.6.13 the global default for Python
pyenv global 3.6.13Then used the installation steps you recommended. However, finding the directories for the following in the reinstall command was a challenge:
dataiku-dss-VERSION
is /Applications/DataScienceStudio.app/Contents/Resources/kit/
DATA_DIR
is /Users/[Your Home Directory]/Library/DataScienceStudio/dss_home
On my computer, the command you described turned out to be:
/Applications/DataScienceStudio.app/Contents/Resources/kit/installer.sh -d
/Users/[Your Home Directory]/Library/DataScienceStudio/dss_home -u -P python3.6Note: You will have to replace your home director where it says [Your Home Directory]
I did not use the environment variable.
# setup the environment variable DKUPYTHONBIN
export DKUPYTHONBIN=/usr/local/bin/python3.7
# test the environment variable
echo $DKUPYTHONBINI did this with DSS 9.0.1 installed by homebrew.

For DSS 10.0.7 on Mac OS 10.15.7 using the new DSS Installer Application the location of the installer.sh file seems to have moved to
DATA_DIR/kits/dataiku-dss-10.0.7-osx
That said I'm was having difficulties getting older code environments to load in DSS 10.0.7. Turns out that a specific python library postal was the culprit. I think that I have things resolved after reinstall of the python Library.
