Input 0 is incompatible with layer flatten_15: expected min_ndim=3, found ndim=2
问题 I am trying to train ANN model on my sound data set, which has 320 rows and 50 columns, while running this code: Model= Sequential([ Flatten(), Dense(16, input_shape=(1,50), activation= 'relu' ) , Dense(32, activation= 'relu' ), Dense(2, activation='softmax' ) , ]) Model.compile(Adam(lr=0.0001), loss='sparse_categorical_crossentropy', metrics=['accuracy']) Model.fit(S_T_S, T_L, validation_split=0.1, batch_size=20, epochs=20, shuffle='true', verbose=2) I am getting error of: Input 0 is
