train_test_split() error: Found input variables with inconsistent numbers of samples

$\begingroup$

Fairly new to Python but building out my first RF model based on some classification data. I've converted all of the labels into int64 numerical data and loaded into X and Y as a numpy array, but I am hitting an error when I am trying to train the models.

Here is what my arrays look like:

>>> X = np.array([[df.tran_cityname, df.tran_signupos, df.tran_signupchannel, df.tran_vmake, df.tran_vmodel, df.tran_vyear]]) >>> Y = np.array(df['completed_trip_status'].values.tolist()) >>> X array([[[ 1, 1, 2, 3, 1, 1, 1, 1, 1, 3, 1, 3, 1, 1, 1, 1, 2, 1, 3, 1, 3, 3, 2, 3, 3, 1, 1, 1, 1], [ 0, 5, 5, 1, 1, 1, 2, 2, 0, 2, 2, 3, 1, 2, 5, 5, 2, 1, 2, 2, 2, 2, 2, 4, 3, 5, 1, 0, 1], [ 2, 2, 1, 3, 3, 3, 2, 3, 3, 2, 3, 2, 3, 2, 2, 3, 2, 2, 1, 1, 2, 1, 2, 2, 1, 2, 3, 1, 1], [ 0, 0, 0, 42, 17, 8, 42, 0, 0, 0, 22, 0, 22, 0, 0, 42, 0, 0, 0, 0, 11, 0, 0, 0, 0, 0, 28, 17, 18], [ 0, 0, 0, 70, 291, 88, 234, 0, 0, 0, 222, 0, 222, 0, 0, 234, 0, 0, 0, 0, 89, 0, 0, 0, 0, 0, 40, 291, 131], [ 0, 0, 0, 2016, 2016, 2006, 2014, 0, 0, 0, 2015, 0, 2015, 0, 0, 2015, 0, 0, 0, 0, 2015, 0, 0, 0, 0, 0, 2016, 2016, 2010]]]) >>> Y array(['NO', 'NO', 'NO', 'YES', 'NO', 'NO', 'YES', 'NO', 'NO', 'NO', 'NO', 'NO', 'YES', 'NO', 'NO', 'YES', 'NO', 'NO', 'NO', 'NO', 'NO', 'NO', 'NO', 'NO', 'NO', 'NO', 'NO', 'NO', 'NO'], dtype='|S3') >>> X_train, X_test, Y_train, Y_test = train_test_split(X, Y, test_size=0.3)

Found input variables with inconsistent numbers of samples: [4, 1]

Closed. This question needs to be more . This question needs to be more focused . It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed last year. Improve this question

this is what I did. The code is down bellow. I have the music.csv dataset. The error is Found input variables with inconsistent numbers of samples: [4, 1]. The error details is after the code.

# importing Data import pandas as pd music_data = pd.read_csv('music.csv') music_data # split into training and testing- nothing to clean # genre = predictions # Inputs are age and gender and output is genre # method=drop X = music_data.drop(columns=['genre']) # has everything but genre # X= INPUT Y = music_data['genre'] # only genre # Y=OUTPUT # now select algorithm from sklearn.tree import DecisionTreeClassifier model = DecisionTreeClassifier() # model model.fit(X, Y) prediction = model.predict([[21, 1]]) from sklearn.model_selection import train_test_split X_train, X_test, y_train, y_test = train_test_split(X, Y, test_size=0.2) # 20% of date=testing # first two input other output model.fit(X_train, y_train) from sklearn.metrics import accuracy_score score = accuracy_score(y_test, predictions)

Then this error comes. This error is a value error

Pls help me. I dont know whats happening but I think it has to do with this score = accuracy_score(y_test, predictions).
