what is this color map? cmap=mglearn.cm3
conda install pip(because conda install mglearn will give a error)
pip install mglearn
grr = pd.plotting.scatter_matrix( ...., cmap=mglearn.cm3)
if you still can't see the output then you might have missed %matplotlib inline
I try to run  the following code but it gives the following error in recognistion of mglearn color map.
grr = pd.scatter_matrix( ...., cmap=mglearn.cm3)
ErrorName: name 'mglearn' is not defined
I should add pd is Anaconda Pandas package imported as pd but does not recognize the color map mglearn.cm3
Any suggestions?
