python - 在 for 循环中创建多个对象

Question

我想在 for 循环中创建多个对象。我的代码是这样的:

regressor1 = Sequential()

# Adding the first LSTM layer and some Dropout regularisation
regressor1.add(LSTM(units = 50, return_sequences = True, input_shape = (X_train.shape[1], 6)))
regressor1.add(Dropout(0.2))

regressor2 = Sequential()

# Adding the first LSTM layer and some Dropout regularisation
regressor2.add(LSTM(units = 50, return_sequences = True, input_shape = (X_train.shape[1], 6)))
regressor2.add(Dropout(0.2))

.
.
.

regressor20 = Sequential()

# Adding the first LSTM layer and some Dropout regularisation
regressor20.add(LSTM(units = 50, return_sequences = True, input_shape = (X_train.shape[1], 6)))
regressor20.add(Dropout(0.2))

我如何在 for 循环中执行此操作？

感谢您的帮助。

模型没有什么特别之处，它们是对象，因此您可以在循环中创建模型对象(回归器)列表:

regressors = list()
for _ in range(20):
  model = Sequential()
  model.add(LSTM(units=50, ...))
  model.add(Dropout(0.2))
  regressors.append(model)
# Now access like you would any array
# regressors[0] etc will give you models.
