I have written the following code for a neural network to perform regression on a dataset, but I am getting a ValueError. I have looked up to different answers and they suggested to use df = df.values to get a numpy array. I tried it but it still produced the same error. How to fix this?


from keras import Sequential
from keras.layers import Dense, Dropout, Flatten
from keras.optimizers import Adam
from sklearn.model_selection import train_test_split

#Define Features and Label
features = ['posted_by', 'under_construction', 'rera', 'bhk_no.', 'bhk_or_rk',
            'square_ft', 'ready_to_move', 'resale', 'longitude',


#Train Test Split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state = 23, shuffle = True)

model = Sequential()
model.add(Dense(10, activation='relu', kernel_initializer='random_normal', input_dim = 10))
model.add(Dense(1, activation = 'relu', kernel_initializer='random_normal'))

#Compiling the neural network
model.compile(optimizer = Adam(learning_rate=0.1) ,loss='mean_squared_logarithmic_error', metrics =['mse'])

#Fitting the data to the training dataset  
model.fit(X_train,y_train, batch_size=256, epochs=100, verbose=0)


ValueError: Failed to convert a NumPy array to a Tensor (Unsupported object type int).
  • $\begingroup$ I am having the same problem. I don't know why it is happening $\endgroup$ – 324 Oct 12 '20 at 0:46

Before fitting the model the training data write the below 2 lines:
