回答1:

You can check for the install packages by typing !conda list in the notebook and check for scikit-learn package is there or not. If it's not present then you can install it by !pip install scikit-learn or !conda install -c anaconda scikit-learn

later try import sklearn it should work!.

There is a useful source here, including how to update or upgrade packages..

final solution: first need activate the environment you are working and install conda package in that particular environment using conda install and do need not to install outside of your environment

sana@skb-linux:~$ . activate my_env (my_env) sana@skb-linux:~$ conda install scikit-learn Solving environment: done

so the sklearn package is installed in your particular environment(in my case its installed my_env)
