问题
I am trying to import sklearn in my jupyter notebook on a macOS Mojave 10.14.3. macOS comes standard with python 2.7. I have installed python3 in addition python 2.7. I am launching jupyter from a virtual env with python3. When I launch jupyter and open a notebook it shows it is running python 3.7.x. When I list "!pip show scipy" from inside the notebook it says scipy 1.2.1 is installed. Still, with all the above, when I say "import scikit" or "import sklearn" I get a ModuleNotFoundError: No module named 'xxxxx' error. xxxx = scikit or sklearn. Any help is appreciated.
