New images always predict one label

$begingroup$


I have trained a SVM for image classification using RGB histogram as features and a couple of other ones.



These are my feature and label sizes:



STATUS] feature vector size (11244, 525)
[STATUS] training Labels (11244,)
[STATUS] training labels encoded...
[STATUS] feature vector normalized...
[STATUS] target labels: [0 0 0 ... 1 1 1]
[STATUS] target labels shape: (11244,)


I am using sklearn's train_test_split with ratio of 0.15 for test.



Following is the classification report(100% recall and precision on test). This is weird!!
