ValueError("Found input variables with inconsistent numbers of" ValueError: Found input variables with inconsistent numbers of samples: [10725, 3575]

I have been stuck with this error for quite a while. Whenever I run this code, I get the following error:

raise ValueError("Found input variables with inconsistent numbers of "ValueError: Found input variables with inconsistent numbers of samples: [10725, 3575]

Here's my code snippet:

n_classes = len(classes)

X_train, X_test, y_train, y_test = train_test_split(X, Y, random_state=0, test_size = 0.75)

X_train_scale = X_train/255.0
X_test_scale = X_test/255.0
Solution

  • You got this error because train_test_split requires that X and Y must have the same length while it's not the case here. In fact :
    X.shape[0] == 10725 while Y.shape[0] == 3575

    To solve this you have to reshape your X. Here is my suggestion:
    X.reshape(Y.shape[0], -1)
