When I execute the 'dss start', the ipython does not start (it remains in FATAL state) and the ipython.log gives this error:
Traceback (most recent call last): File "/home/administrador/Dataiku/dataiku-dss-5.1.2/dku-jupyter/dkulauncher.py", line 1, in <module> from notebook.notebookapp import main ImportError: No module named notebook.notebookapp
Is there any way to know which python is this using so I can install the notebook module??
DSS uses Python 2.7 (sourcing it from the PATH environment variable). Upon installation, it creates a code environment inside the data-dir folder.
For your particular issue, I suggest to have a look at the installation log file, located into data-dir/run/install.log. The packages needed should have been installed by DSS automatically upon installation so probably something went wrong.
