Python numpyArray shape issue

Error:- ValueError: Found input variables with inconsistent numbers of samples: [150, 1] 

Solution: use numpy reshape method. 

 You are getting that error because your X and Y don't have the same length (which is what train_test_split requires), it means that ., X.shape[0] != Y.shape[0]. 

see below code:

 >>> X.shape (1, 5, 20)

 >>> Y.shape (20,) 

To fix this error: Remove the extra list from inside of np.array() when defining X or remove the extra dimension afterwards with the following command: 

 X = X.reshape(X.shape[1:]). 

 Now, the shape of X will be (5, 20). 

Transpose X by doing X = X.tranpose() to get equal number of samples in X and Y. 

 Now, the shape of X will be (20, 6) and the shape of Y will be (20,).
