I've installed jupyter lab from within the virtualenv - WHY ON EARTH would I want sys.executable to point to anywhere but to the same value that will be returned when launching python from the virtualenv? When running a notebook, sys.executable still returns: they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. 0.

I don't think made any upgrades, but I could try and delete anaconda and reinstall it. jupyter notebook --generate-config, and the only configurations I have "enabled" in my config file are:

pip3 install --upgrade pip3 setuptools wheel It turns out that I'm installing the python3 version of jupyter with python2. Does every open orientable even-dimensional smooth manifold admit an almost complex structure? I changed the first argument of argv in python3 folder's kernel.json from python2 path to python3 path, and everything works as expected. Any idea on how to reduce or merge them like ubuntu 16?
