train_test_split is not stratified.
In master, you can use "stratify=y" to make it stratified.
Also: randomness.

I wouldn't expect those splits to be the same by nature. And additionally
you are seeding the randomness differently in the two cases. Take a close
look at the generated splits - maybe their composition already explains the
discrepancies.

I am seeing a discrepancy between classification performance between two cross
validation technique using the same data. I was wondering if anyone can shed
some light on this.
Thanks in advance for your help.

Method 1: cross_validation.train_test_split
Method 2: StratifiedKFold.
