I cannot import sklearn.model_selection.train_test_split

Question

When I want to import sklearn.model_selection, I get this error:

I want to run my code on a server and I do not have admin rights to reinstall python or sklearn.

Answer 1

Make sure you have all the requirement. Some modules require extra software to be installed. Such as a C++ compiler for some. If you are using Linux a simple command such as python yourmodule.py could work as well. So just double check the instructions and make sure you are doing everything right because installing modules can be very fishy and hard. And for the Admin rights: If you are having a company hosting this server for you then you may have to get the rights from them or it may be impossible if they don't allow it.
