I'm trying to test this flexbox layout model in compass.
I run into problem, when I copy entire example to my localhost: http://compass-style.org/examples/compass/css3/flexbox/
I get following error:
error: assets/sass/main.scss (Line 94 of /Users/xyz/.rvm/gems/ruby-2.0.0-p481#global/gems/compass-core-1.0.1/stylesheets/compass/css3/_flexbox.scss: Mixin flexbox takes 0 arguments but 1 was passed.)
To compile my scss files I use grunt-contrib-compass
ruby: 2.0.0p481 (2014-05-08 revision 45883) [x86_64-darwin13.1.0]
compass: Compass 1.0.1 (Polaris)
Sass 3.4.3 (Selective Steve)
grunt-contrib-compass: "~0.9.1"
Same error I get when I run 'Compass watch'.
Any ideas why is this happening?

It was a but, I had duplicate mixin :P

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

Any time i type the 'unmask' command in my bash terminal i get the error below:
'bash: unmask: command not found'
Please, any ideas on how i can solve this problem, I believe 'unmask' is a built in command.
I am using bash --version 5.0.16(1)
Could it be that you actually meant umask?

I'm trying to install a library of collections, a module сounter and defaultdict.
I have python 3.6 and Win 7 64x installed. When installing the "pip install collections" library, an error appears. "The version that satisfies the requirement sets could not be found".
How to fix this problem?
The Collections module is a built-in module and comes with a base installation of Python, both for Python 2 and Python 3, and therefore doesn't need to be installed (and will not be found on PyPI). You can find a list of these modules here
