我已经在Windows 10,Python 3.5,Keras 2.0.6中培训并保存了Keras模型。Python Keras - Windows和Linux之间的兼容性
在Windows中,我可以加载模型并重用它。但是,当我尝试在Linux操作系统(Ubuntu的),Keras 2.0.5,加载模型我得到以下错误:
ValueError: Optimizer weight shape (90,) not compatible with provided weight shape (31, 90)
我试图卸载Keras和使用皮普重新安装,然后做同样的与康达。这是与Windows和Linux的兼容性问题,还是其他?
非常感谢
码培养和保存模型:
from keras.models import Sequential
from keras.layers import Dense
import keras.backend as K
def inRange(y_true, y_pred):
return K.sum(K.cast(K.less_equal(K.abs(y_true-y_pred), 8), "int32"))/K.shape(y_true)[0]
# create model
model = Sequential()
model.add(Dense(n1, input_dim=X_train.shape[1], activation='relu'))
model.add(Dense(n2, activation='relu'))
model.add(Dense(1, activation='linear'))
# Compile model
model.compile(loss='mean_squared_error', optimizer='adam', metrics=['accuracy', inRange])
# Fit the model
history = model.fit(X_train, y_train, epochs=maxEpoch, batch_size=10)
# evaluate the model
scores = model.evaluate(X_train, y_train)
print("\n%s: %.2f%%" % (model.metrics_names[1], scores[1]*100))
# save the model
model.save('length_predict.h5', overwrite=True, include_optimizer=True)
代码加载保存的模型:
import keras.backend as K
from keras.models import load_model
# Custom metric for use in the keras ANN models, needs to be loaded as a custom object
def inRange(y_true, y_pred):
'''
Function for determining the percentage of points that fall within the +-8% error
'''
return K.sum(K.cast(K.less_equal(K.abs(y_true-y_pred), 8), "int32"))/K.shape(y_true)[0]
# Load the ANN
model_length = load_model('length_predict.h5', custom_objects={'inRange':inRange})
请提供您的模型的一些代码 – Paddy
@Paddy我已经添加了一些代码片段。谢谢 – jlt199
建议仔细检查Windows/Linux上的keras版本。需要完全相同。 –
