Question

我在做语音情感识别项目。它在一周前工作，我升级了 anaconda，但我以前使用的代码运行不再有效。我找不到问题它给出了标题中的错误。我的代码是：

# New model

model = Sequential()
model.add(Conv1D(256, 8, padding='same',input_shape=(X_train.shape[1],1)))  # X_train.shape[1] = No. of Columns
model.add(Activation('relu'))
model.add(Conv1D(256, 8, padding='same'))
model.add(BatchNormalization())
model.add(Activation('relu'))
model.add(Dropout(0.25))
model.add(MaxPooling1D(pool_size=(8)))
model.add(Conv1D(128, 8, padding='same'))
model.add(Activation('relu'))
model.add(Conv1D(128, 8, padding='same'))
model.add(Activation('relu'))
model.add(Conv1D(128, 8, padding='same'))
model.add(Activation('relu'))
model.add(Conv1D(128, 8, padding='same'))
model.add(BatchNormalization())
model.add(Activation('relu'))
model.add(Dropout(0.25))
model.add(MaxPooling1D(pool_size=(8)))
model.add(Conv1D(64, 8, padding='same'))
model.add(Activation('relu'))
model.add(Conv1D(64, 8, padding='same'))
model.add(Activation('relu'))
model.add(Flatten())
model.add(Dense(14)) # Target class number
model.add(Activation('softmax'))
# opt = keras.optimizers.SGD(lr=0.0001, momentum=0.0, decay=0.0, nesterov=False)
# opt = keras.optimizers.Adam(lr=0.0001)
opt = tf.keras.optimizers.RMSprop(lr=0.00001, decay=1e-6)
model.summary()

# %%
model.compile(loss='categorical_crossentropy', optimizer=opt,metrics=['accuracy'])
model_history=model.fit(X_train, y_train, batch_size=16, epochs=100, validation_data=(X_test, y_test))

我收到这个错误

我的值错误代码是

    df_cm = pd.DataFrame(
        confusion_matrix, index=class_names, columns=class_names, 
    )
    fig = plt.figure(figsize=figsize)
    try:
        heatmap = sns.heatmap(df_cm, annot=True, fmt="d")
    except ValueError:
        raise ValueError("Confusion matrix values must be integers.")

def gender(row):
    if row == 'kadin_igrenme' or 'kadin_korku' or 'kadin_mutlu' or 'kadin_uzgun' or 'kadin_saskin' or 'kadin_sakin':

谁能帮帮我编辑我添加了 x 列 y 列形状

print(X_train.shape)
print(y_train.shape)
print(y_test.shape)
print(X_test.shape)
print(lb.classes_)
#print(y_train[0:10])
#print(y_test[0:10])

(9031, 216, 1) (9031, 15) (3011, 15) (3011, 216, 1) [1]: https://i.stack.imgur.com/LKZDB.png

Answer 1

问题在于网络输出形状。由于标签具有形状

(b, 15) where b = 9031 for train and 3011 for test

网络中最后的密集层也应该有 15 个神经元。将最后一层更新为

model.add(Dense(15)

它应该可以正常工作。

raise ValueError("Shapes %s and %s are incompatible" % (self, other)) ValueError: Shapes (None, 15) and (None, 14) are incompatible

raise ValueError("Shapes %s and %s are incompatible" % (self, other)) ValueError: Shapes (None, 15) and (None, 14) are incompatible
