I am new to machine learning. I am trying to learn feature selection from this link. Here they have a line of code which is given below
search = GridSearchCV(pipeline, grid, scoring='neg_mean_squared_error', n_jobs=-1, cv=cv)
But whenever I try to run this code I get the error
I cannot find where to import neg_mean_squared_error from. I am not sure where I should write the function myself or not. The tutorial isn't clear on this issue.
It is just a typo.
You need
neg_mean_absolute_error
You typed
neg_mean_absolure_error
using an r instead of t

When I type > file.extension I know that the file is replaced by a empty file.
What if then I type > / ? My / partition will be erased and I'll lost everything in it?
I'm curious and wondering if someone already tried this.
You cannot redirect to a directory
