Python 在for循环中创建多个对象

我想在for循环中创建多个对象。我的代码如下：

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))

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.

您必须首先创建对象，然后添加到列表中

然后迭代它们以添加细节

lst = [x.Sequential() for x in range(20)]

for i in lst:
    i.add(LSTM(units = 50, return_sequences = True, input_shape = (X_train.shape[1], 6)))
    i.add(Dropout(0.2))

---

可以创建对象列表。 例如：

regressor_list = []
for x in range(0,20):
    regressor = Sequential()
    regressor_list.append(regressor)

现在对于e.x.您可以访问第五个回归器对象，如回归器_列表[5]。

希望这对你有所帮助：）

难看的一行如下

layer_str = "Sequential().add(LSTM(units = 50, return_sequences = True, input_shape = (X_train.shape[1], 6))).add(Dropout(0.2))"

models_lst = [eval(layer_str) for i in range(1,21)]

注：我建议使用其他答案。但是，我只是想表明，这也可以通过这种方式实现
